Advances in computer technology (e.g., microprocessor speed, memory capacity, data transfer bandwidth, software functionality, and the like) have generally contributed to increased computer application in various industries. Ever more powerful server systems, which are often configured as an array of servers, are commonly provided to service requests originating from external sources such as the World Wide Web, for example.
In light of such advances, the amount of available electronic data grows and it becomes more important to store such data in a manageable manner that facilitates user friendly and quick data searches and retrieval. Today, a common approach is to store electronic data in one or more databases or data stores. In general, a typical data store can be referred to as an organized collection of information with data structured such that a computer program can quickly search and select desired pieces of data, for example. Commonly, data within a data store is organized via one or more tables. Such tables are arranged as an array of rows and columns.
With the advent of highly sophisticated computer software and/or hardware, new services have emerged to meet the consumer demands associate with such sophisticated computer hardware and/or software. Typically, computational services are undertaken upon a client or within a proprietary intranet. Client-side systems are employed to manage relationships between users, software applications, services, and hardware within a client machine, as well as data resident upon a respective intranet. However, in addition to client-side systems providing services, off-site systems (e.g., third party) can also provide services in order to improve data capability, integrity, reliability, versioning, security, and mitigate costs associated therewith.
In general, these services can be employed to manage relationship between users, provide software applications, enhance hardware capabilities, manage data, optimize security, etc. For example, a third party service can enable a client to store data therewith limited solely by the third party capabilities (e.g., hardware, software, etc.). In particular, the off-site or remote data storing services enable users to access data storage via the Internet or the web for data upload or download. Such off-site or remote data storage service providers can provide backup functionality and techniques including redundancy, safe-guarding, privacy, and safe-guards against losing data.
The following presents a simplified summary of the innovation in order to provide a basic understanding of some aspects described herein. This summary is not an extensive overview of the claimed subject matter. It is intended to neither identify key or critical elements of the claimed subject matter nor delineate the scope of the subject innovation. Its sole purpose is to present some concepts of the claimed subject matter in a simplified form as a prelude to the more detailed description that is presented later.
The subject innovation relates to systems and/or methodologies that facilitate utilization of recipes to build or re-build files. In one aspect, recipes can be employed in a distributed data storage environment such as network-based backup architectures. For instance, recipes can be employed to represent files or other data derived from base information. Accordingly, storage resources can be efficiently utilized as derived data need not be stored. Rather, instructions to construct the derived data can be stored. When data associated with a recipe is requested, the data can be constructed, on the fly, in accordance with the recipe.
In accordance with another aspect, recipes can be evaluated to identify possible modifications thereto to improve efficiency, facilitate file format migration, and/or customize a recipe to a particular application. For example, different base information can be identified and employed in connection with a recipe. In addition, an order of operations in a recipe can be changed and/or one or more operations can be skipped, replaced with more efficient functions, and the like.
The following description and the annexed drawings set forth in detail certain illustrative aspects of the claimed subject matter. These aspects are indicative, however, of but a few of the various ways in which the principles of the innovation may be employed and the claimed subject matter is intended to include all such aspects and their equivalents. Other advantages and novel features of the claimed subject matter will become apparent from the following detailed description of the innovation when considered in conjunction with the drawings.
The claimed subject matter is described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the subject innovation. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the subject innovation.
As utilized herein, terms “component,” “system,” “data store,” “cloud,” “peer,” “super peer,” “client,” and the like are intended to refer to a computer-related entity, either hardware, software in execution on hardware, and/or firmware. For example, a component can be a process running on a processor, an object, an executable, a program, a function, a library, a subroutine, and/or a computer or a combination of software and hardware. By way of illustration, both an application running on a server and the server can be a component. One or more components can reside within a process and a component can be localized on one computer and/or distributed between two or more computers.
Various aspects will be presented in terms of systems that may include a number of components, modules, and the like. It is to be understood and appreciated that the various systems may include additional components, modules, etc. and/or may not include all of the components, modules, etc. discussed in connection with the figures. A combination of these approaches may also be used. The various aspects disclosed herein can be performed on electrical devices including devices that utilize touch screen display technologies and/or mouse-and-keyboard type interfaces. Examples of such devices include computers (desktop and mobile), smart phones, personal digital assistants (PDAs), and other electronic devices both wired and wireless.
Furthermore, the claimed subject matter may be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques to produce software, firmware, hardware, or any combination thereof to control a computer to implement the disclosed subject matter. The term “article of manufacture” as used herein is intended to encompass a computer program accessible from any computer-readable device, carrier, or media. For example, computer readable media can include but are not limited to magnetic storage devices (e.g., hard disk, floppy disk, magnetic strips . . . ), optical disks (e.g., compact disk (CD), digital versatile disk (DVD) . . . ), smart cards, and flash memory devices (e.g., card, stick, key drive . . . ). Additionally it should be appreciated that a carrier wave can be employed to carry computer-readable electronic data such as those used in transmitting and receiving electronic mail or in accessing a network such as the Internet or a local area network (LAN). Of course, those skilled in the art will recognize many modifications may be made to this configuration without departing from the scope or spirit of the claimed subject matter.
Moreover, the word “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the word exemplary is intended to disclose concepts in a concrete fashion. As used in this application, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
Now turning to the figures,
The recipe 104 can include a listing of instructions, operations, and/or transformations to construct a file from other information. In one example, the recipe 104 can indicate specific codecs to apply at particular steps. In another example, the recipe 104 can specify particular features of applications to employ. For instance, the recipe 104 can include a sequence of image editing tools to utilize to on a base image recreate a modified image. It is to be appreciated that recipe 104 can be presented in any suitable language form to enable build component 102 to implement instructions specified therein.
In another aspect, recipe 104 can include content (e.g., unique content, shared content, etc.) to enable a file to be reconstructed from the included content. For instance, recipe 104 can be employed to reconstruct a file from base information (e.g., a portion of content) and a series of differentials. For example, a set of photographs can be obtained via a digital camera is quick succession. The photographs can be similar such that the photographs can be stored as a single base form (e.g., a first photograph in the set) and a series of masks that transform one photograph (e.g., the base) into a second photograph in the set. In another example, document files (e.g., word processing documents, spreadsheets, presentations, etc.) can be represented with recipe 104. For instance, an original unedited version of a document file can be a base form and a series of differentials can be included in recipe 104 to transform the document file in accordance with each edit. Accordingly, recipe 104 can include content in addition to or in place of instructions, operations, and/or transformations as described above.
The build component 102 can employ recipe 104 and other recipes (not shown) to generate a variety of file products. In one example, recipe 104 can specify a sequence of steps (e.g., instructions, transformations, operations, etc.) to modify a portion of data into a particular file. In another example, build component 102 can utilize encoding/decoding schemes specified by recipe 104 to migrate a file of one format to a file of another format. In addition, the recipe 104 can instruct the build component 102 to sample and/or combine disparate portions of data to generate a new file. For example, a video file can be generated from a recipe that instructs the build component 102 to cut and organize clips from a plurality of disparate video files.
In an aspect, the build component 102 can initiate a construction from recipe 104 transparently and/or by request from a user, application, client machine, etc. For example, a user, application, and/or client machine can request a file to be built from a recipe. In another example, the user, application and/or client machine can request access to a file absent prior knowledge as to whether the file exists or requires reconstruction from a recipe. In such example, the recipe can mimic existence of the file while internally specifying content and/or operations to build the file. For instance, the file can be generated and cached for a period of time before being removed to free storage space. In such cases, the build component 102 can implement recipe 104 and deliver the requested file. Otherwise, a cached copy of the file can be provided.
In accordance with another aspect, system 100 can include an evaluation component 108 that analyzes recipe 104. The evaluation component 104 can examine recipe 104 to infer substitutions and/or modifications to recipe 104 to improve quality of generated files and/or direct recipe 104 to implement a particular result (e.g., a special file format, etc.). According to one example, the evaluation component 108 can analyze recipe 104 and identify a portion of data as a starting point that differs from a portion of data indicated in recipe 104 to generate a particular result (e.g., a special file format, etc.) that differs from a product specified by recipe 104. In another example, the evaluation component 108 can identify operations and/or a series of operations that can be skipped and/or replaced with more efficient actions to efficiently implement recipe 104 while preserving a final product of recipe 104.

In accordance with another aspect, the data store 106 can be a file system configured to operate with recipes. In one example, the file system (e.g., data store 106) can maintain base information while discarding data derived from the base information. The discarded data can be replaced with recipes that can be executed to regenerate the discarded data. The file system can maintain the discarded data in an index such that the file system appears to persist the data. The file system can employ the recipes to transparently regenerate the discarded data upon request After regeneration, the file system can persist the data for a period of time and remove the data after the period of time lapses.

The system 302 can further utilize a cloud 304 that can include data storage 306 that retains data, recipes, applications, etc. It is to be appreciated that the cloud 502 can include any suitable component, device, hardware, and/or software associated with the subject innovation. The cloud 304 can refer to any collection of resources (e.g., hardware, software, combination thereof, etc.) that are maintained by a party (e.g., off-site, on-site, third party, etc.) and accessible by an identified user (not shown) over a network (e.g., Internet, wireless, LAN, cellular, Wi-Fi, WAN, etc.). The cloud 304 is intended to include any service, network service, cloud service, collection of resources, etc. and can be accessed by an identified user via a network. For instance, two or more users can access, join, and/or interact with the cloud 304 and, in turn, the data storage 306.
The cloud 304 can provide remote or online data storage or archiving of information. To enable efficient utilization of storage space, recipes can be employed. For example, data storage 306 of cloud 304 can store recipe 308 (as well as additional recipes) that can be employed by build component 102 in connection with a portion of data 310 to generate a file. Thus, cloud 304 can retain a portion of data 310 and recipes, such as recipe 308, which generate derivations of the portion of data 310 instead of storing data 310 and any derived data.
In another aspect, the client machine 302 can include a recipe component 312 that facilitates archiving data (e.g., files, system images, and/or other information) as recipes. In one example, the recipe component 312 can observe modifications to a file and record such modifications to a new recipe. For instance, the recipe component 312 can track operations, transformations, or other functions applied to a file. The recipe component 312 can cache the original file for preservation. In the alternative, the client machine can temporarily render modifications to a file in real-time while safeguarding the original. When a user saves a file or commits a file to persistent storage, the recipe component 312 can generate a recipe to build the modified file from the original.
In accordance with another example, the recipe component 312 can interact with other applications (not shown) to generate recipes. For instance, a particular application can edit files by recording a sequence of operations. The recipe component 312 can translate recorded sequences of operations from the application into a recipe format suitable for employment by the build component 102 and/or the evaluation component 108.

Cloud 304 can manage locality of information retained therein. Cloud 304 can distribute portions of information among storage locations 402 such that availability and optimal locality is maintained while reducing storage costs, bandwidth costs, and latency times upon restoration. Cloud 304 can evaluate characteristics of storage locations 402 and distribute chunks of backup data accordingly. The characteristics can include availability of storage locations (e.g., based on device activity levels, powered-on or powered-off status, etc.), available storage space at locations, cost of storage at locations, cost of data transfer to/from locations, network locality of locations (e.g., network topology), and the like. In one example, cloud 304 can distribute more data to storage locations with higher storage capability and availability than to other storage locations (e.g., normal client machines).
In another aspect, system 400 can include a client machine 410 and an application 420. The client machine 410 can include a build component 412, an evaluation component 414, and a recipe component 416. Similarly, the application 420 can include a build component 422, an evaluation component 424, and a recipe component 426. It is to be appreciated that the build components 412 and 422, the evaluation components 414 and 424, and the recipe components 416 and 426 can be similar to and perform similar functions as build component 102, evaluation component 108, and recipe component 312 described herein with reference to

In accordance with one aspect, cloud 510 can be utilized to remotely implement one or more computing services from a given location on a network/internetwork associated with super peer(s) 520 and/or peer(s) 530-540 (e.g., the Internet). Cloud 510 can originate from one location, or alternatively cloud 510 can be implemented as a distributed Internet-based service provider. In one example, cloud 510 can be utilized to provide backup or other storage functionality to one or more peers 520-540 associated with cloud 510. Accordingly, cloud 510 can implement a backup service 512 and/or provide associated data store 514.
In one example, data storage 514 can interact with a backup client 522 at super peer 520 and/or backup clients 532 or 542 at respective peers 530 or 540 to serve as a central storage location for data residing at the respective peer entities 520-540. In this manner, cloud 510, through data storage 514, can effectively serve as an online “safe-deposit box” for data located at peers 520-540. It can be appreciated that backup can be conducted for any suitable type(s) of information, such as files (e.g., documents, photos, audio, video, etc.), system information, and/or chunks of files or system information. Additionally or alternatively, distributed network storage can be implemented, such that super peer 520 and/or peers 530-540 are also configured to include respective data storage 524, 534, and/or 544 for backup data associated with one or more machines on the associated local network. In another example, techniques such as de-duplication, incremental storage, and/or other suitable techniques can be utilized to reduce the amount of storage space required by data storage 514, 524, 534, and/or 544 at one or more corresponding entities in the network represented in
In accordance with another aspect, cloud 510 can interact with one or more peer machines 520, 530, and/or 540. As illustrated in
In one example, super peer 520 can be a central entity on a network associated with peers 520-540, such as an enterprise server, a home server, and/or any other suitable computing device(s) determined to have the capability for acting as a super peer in the manners described herein. In addition to standard peer functionality, super peer(s) 520 can be responsible for collecting, distributing, and/or indexing data among peers 520-540 in the local network. For example, super peer 520 can maintain a storage index 526, which can include the identities of respective files and/or file segments corresponding to peers 520-540 as well as pointer(s) to respective location(s) in the network and/or in cloud data storage 514 where the files or segments thereof can be found. In another aspect, peers 530 and 540 can include respective indexes 536 and 546 which can include local cache of at least a portion of storage index 526. Although shown in
It is to be appreciated that the data stores illustrated in system 500 (e.g., data stores 514, 524, 534, and 544) can be, for example, either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. By way of illustration, and not limitation, nonvolatile memory can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), or flash memory. Volatile memory can include random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation, RAM is available in many forms such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), Rambus direct RAM (RDRAM), direct Rambus dynamic RAM (DRDRAM), and Rambus dynamic RAM (RDRAM). The data store of the subject systems and methods is intended to comprise, without being limited to, these and any other suitable types of memory. In addition, it is to be appreciated that the data stores can be a server, a database, a hard drive, a pen drive, an external hard drive, a portable hard drive, and the like.

In one example, peer machines 620 can include respective data stores 622, which can be utilized to receive and maintain backup information corresponding to one or more files, system images, or other information. Backup information stored in data stores 622 can be associated with, for example, a restoring peer 610. The backup information can include chunks of files or other data generated by the restoring peer 610 (or another device) via remote differential compression, for example. In addition, the restoring peer 610 can additionally or alternatively include a data store 616 for locally storing backup information (or chunks thereof) corresponding to files, versions of files, system images, and the like, residing locally at restoring peer 610.
In another example, one or more super peers 630 in system 600 can additionally include a data store 632 as well as an index 634, which can provide a master listing of blocks of backup information stored within system 600 and their respective locations. Although index 634 is illustrated as located at super peer 630 in system 600, it should be appreciated that some or all of index 634 could additionally or alternatively be located at one or more peers 610 and/or 620 as well as at cloud storage 640.
In accordance with one aspect, the restoring peer 610 can include a restore component 614 that can issue a restore request. The restore request can be a request to roll-back a version of file retained by the restoring peer 610 with a previous version distributed in system 600. In another example, the restore request can be a command to recover a version (e.g., a most recent version, an original version and/or any version therebetween). An index lookup component 612 can obtain metadata from index 634 and/or any other suitable source that points to the respective locations of file versions to be restored.
Based on the locations obtained by index lookup component 612, the restore component 614 can pull blocks of backup information from their corresponding locations within data store(s) 622, 632, 642, and/or any other suitable storage location within system 600. Accordingly, in one example, a restore can be conducted by pulling incremental delta chunks necessary to recreate a desired version. In another example, a complete rendition of the desired version can be located and obtained.
In accordance with another example, the hybrid P2P/cloud backup architecture of system 600 can be exploited to minimize latency and/or bandwidth required to restore one or more file versions at a restoring peer 610. For example, restore component 614 can analyze system 600 to facilitate pulling of respective blocks from the path of least resistance through system 600. Thus, for example, in the event that a given block resides at data store 622 or 632 at a peer 620 or super peer 630 as well as in cloud storage 640, preference can be given to pulling the block from the nearest network nodes first. As a result, a peer 620 and/or super peer 630 can be prioritized over cloud storage 640 to minimize the latency and bandwidth usage associated with communicating with cloud storage 640. In addition, restore component 614 can analyze availability of respective nodes in system 600, relative network loading and/or other factors to facilitate intelligent selection of nodes from which to obtain file versions. Accordingly, the restoring peer 610 can be configured to first attempt to obtain blocks from a peer machine 620 or a super peer 630, falling back on cloud storage 640 only if no peers 620 and/or 630 with required file versions are available. In an alternative example, super peer 630 and/or another entity from which the restoring peer 610 accesses index 634 can utilize similar network analysis in order to select an optimal location from among a plurality of locations that retains a block as indicated by the index 634. Once selected, such location(s) can be subsequently provided to a restoring peer 610.
The intelligence component 702 can employ value of information (VOI) computation in order to implement and/or modify recipes. For instance, by utilizing VOI computation, the most ideal and/or appropriate recipes, the most ideal base information, or the most appropriate transform improvements can be determined. Moreover, it is to be understood that the intelligence component 702 can provide for reasoning about or infer states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources. Various classification (explicitly and/or implicitly trained) schemes and/or systems (e.g., support vector machines, neural networks, expert systems, Bayesian belief networks, fuzzy logic, data fusion engines . . . ) can be employed in connection with performing automatic and/or inferred action in connection with the claimed subject matter.
A classifier is a function that maps an input attribute vector, x=(x1, x2, x3, x4, xn), to a confidence that the input belongs to a class, that is, f(x)=confidence(class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to prognose or infer an action that a user desires to be automatically performed. A support vector machine (SVM) is an example of a classifier that can be employed. The SVM operates by finding a hypersurface in the space of possible inputs, which hypersurface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches include, e.g., naïve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein also is inclusive of statistical regression that is utilized to develop models of priority.
The build component 102 and evaluation component 108 can further utilize a presentation component 704 that provides various types of user interfaces to facilitate interaction between a user and any component coupled to system 700. As depicted, the presentation component 704 is a separate entity that can be utilized with the build component 102 and evaluation component 108. However, it is to be appreciated that the presentation component 704 and/or similar view components can be incorporated into the build component 102 and evaluation component 108/or a stand-alone unit. The presentation component 704 can provide one or more graphical user interfaces (GUIs), command line interfaces, and the like. For example, a GUI can be rendered that provides a user with a region or means to load, import, read, edit etc., data, and can include a region to present the results of such. These regions can comprise known text and/or graphic regions comprising dialogue boxes, static controls, drop-down-menus, list boxes, pop-up menus, as edit controls, combo boxes, radio buttons, check boxes, push buttons, and graphic boxes. In addition, utilities to facilitate the presentation such as vertical and/or horizontal scroll bars for navigation and toolbar buttons to determine whether a region will be viewable can be employed.
The user can also interact with the regions to select and provide information via various devices such as a mouse, a roller ball, a touchpad, a keypad, a keyboard, a touch screen, a pen and/or voice activated mechanism, a body motion detection mechanism, for example. Typically, a mechanism such as a push button or the enter key on the keyboard can be employed subsequent entering the information in order to initiate the search. However, it is to be appreciated that the claimed subject matter is not so limited. For example, merely highlighting a check box can initiate information conveyance. In another example, a command line interface can be employed. For example, the command line interface can prompt (e.g., via a text message on a display and an audio tone) the user for information via providing a text message. The user can then provide suitable information, such as alpha-numeric input corresponding to an option provided in the interface prompt or an answer to a question posed in the prompt. It is to be appreciated that the command line interface can be employed in connection with a GUI and/or API. In addition, the command line interface can be employed in connection with hardware (e.g., video cards) and/or displays (e.g., black and white, EGA, VGA, SVGA, etc.) with limited graphic support, and/or low bandwidth communication channels.

At reference numeral 806, the recipe can be evaluated to identify possible modifications. In one example, the recipe can be analyzed to infer substitutions and/or modifications that improve quality of generated data and/or direct the recipe to implement a specific result (e.g., a special file format). For instance, disparate base information can be identified. In addition, operations and/or a series of operations that can be skipped can be identified. Further, operations specified in the recipe can be identified as obsolete in view of more efficient actions.
At reference numeral 806, the recipe is amended in accordance with the evaluation. For instance, operations can be resequenced, skipped, and/or replaced. At reference numeral 810, the portion of data can be built based upon the amended recipe.

Communication media typically embodies computer-readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism, and includes any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media includes wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. Combinations of the any of the above should also be included within the scope of computer-readable media.

With reference to
The system bus 1008 can be any of several types of bus structure that may further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory 1006 includes read-only memory (ROM) 1010 and random access memory (RAM) 1012. A basic input/output system (BIOS) is stored in a non-volatile memory 1010 such as ROM, EPROM, EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer 1002, such as during start-up. The RAM 1012 can also include a high-speed RAM such as static RAM for caching data.
The computer 1002 further includes an internal hard disk drive (HDD) 1014 (e.g., EIDE, SATA), which internal hard disk drive 1014 may also be configured for external use in a suitable chassis (not shown), a magnetic floppy disk drive (FDD) 1016, (e.g., to read from or write to a removable diskette 1018) and an optical disk drive 1020, (e.g., reading a CD-ROM disk 1022 or, to read from or write to other high capacity optical media such as the DVD). The hard disk drive 1014, magnetic disk drive 1016 and optical disk drive 1020 can be connected to the system bus 1008 by a hard disk drive interface 1024, a magnetic disk drive interface 1026 and an optical drive interface 1028, respectively. The interface 1024 for external drive implementations includes at least one or both of Universal Serial Bus (USB) and IEEE-1394 interface technologies. Other external drive connection technologies are within contemplation of the subject disclosure.
The drives and their associated computer-readable media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 1002, the drives and media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable media above refers to a HDD, a removable magnetic diskette, and a removable optical media such as a CD or DVD, it should be appreciated by those skilled in the art that other types of media which are readable by a computer, such as zip drives, magnetic cassettes, flash memory cards, cartridges, and the like, may also be used in the exemplary operating environment, and further, that any such media may contain computer-executable instructions for performing the methods described herein.
A number of program modules can be stored in the drives and RAM 1012, including an operating system 1030, one or more application programs 1032, other program modules 1034 and program data 1036. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 1012. It is appreciated that the claimed subject matter can be implemented with various commercially available operating systems or combinations of operating systems.
A user can enter commands and information into the computer 1002 through one or more wired/wireless input devices, e.g., a keyboard 1038 and a pointing device, such as a mouse 1040. Other input devices (not shown) may include a microphone, an IR remote control, a joystick, a game pad, a stylus pen, touch screen, or the like. These and other input devices are often connected to the processing unit 1004 through an input device interface 1042 that is coupled to the system bus 1008, but can be connected by other interfaces, such as a parallel port, a serial port, an IEEE-1394 port, a game port, a USB port, an IR interface, etc.
A monitor 1044 or other type of display device is also connected to the system bus 1008 via an interface, such as a video adapter 1046. In addition to the monitor 1044, a computer typically includes other peripheral output devices (not shown), such as speakers, printers, etc.
The computer 1002 may operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 1048. The remote computer(s) 1048 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer 1002, although, for purposes of brevity, only a memory/storage device 1050 is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1052 and/or larger networks, e.g., a wide area network (WAN) 1054. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which may connect to a global communications network, e.g., the Internet.
When used in a LAN networking environment, the computer 1002 is connected to the local network 1052 through a wired and/or wireless communication network interface or adapter 1056. The adapter 1056 may facilitate wired or wireless communication to the LAN 1052, which may also include a wireless access point disposed thereon for communicating with the wireless adapter 1056.
When used in a WAN networking environment, the computer 1002 can include a modem 1058, or is connected to a communications server on the WAN 1054, or has other means for establishing communications over the WAN 1054, such as by way of the Internet. The modem 1058, which can be internal or external and a wired or wireless device, is connected to the system bus 1008 via the serial port interface 1042. In a networked environment, program modules depicted relative to the computer 1002, or portions thereof, can be stored in the remote memory/storage device 1050. It will be appreciated that the network connections shown are exemplary and other means of establishing a communications link between the computers can be used.
The computer 1002 is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, restroom), and telephone. This includes at least Wi-Fi and Bluetooth™ wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.
Wi-Fi, or Wireless Fidelity, is a wireless technology similar to that used in a cell phone that enables a device to send and receive data anywhere within the range of a base station. Wi-Fi networks use IEEE-802.11 (a, b, g, etc.) radio technologies to provide secure, reliable, and fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE-802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 13 Mbps (802.11a) or 54 Mbps (802.11b) data rate, for example, or with products that contain both bands (dual band). Thus, networks using Wi-Fi wireless technology can provide real-world performance similar to a 10 BaseT wired Ethernet network.
