In computing, a shared resource, or network share, is a computer resource made available from one host to other hosts on a computer network.〔 〕〔 〕 It is a device or piece of information on a computer that can be remotely accessed from another computer, typically via a local area network or an enterprise intranet, transparently as if it were a resource in the local machine. Network sharing is made possible by inter-process communication over the network.〔〔 〕 Some examples of shareable resources are computer programs, data, storage devices, and printers. E.g. shared file access (also known as ''disk sharing'' and ''folder sharing''), shared printer access (''printer sharing''), shared scanner access, etc. The shared resource is called a ''shared disk'' (also known as mounted disk), ''shared drive volume'', ''shared folder'', ''shared file'', ''shared document'', ''shared printer'' or ''shared scanner''. The term ''file sharing'' traditionally means shared file access, especially in the context of operating systems and LAN and Intranet services, for example in Microsoft Windows documentation.〔Microsoft Technet, (File and Printer Sharing in Windows Vista ), May 14, 2007〕 Though, as BitTorrent and similar applications became available in the early 2000s, the term ''file sharing'' increasingly has become associated with peer-to-peer file sharing over the Internet. ==Common file systems and protocols== Shared file and printer access require an operating system on the client that supports access to resources on a server, an operating system on the server that supports access to its resources from a client, and an application layer (in the four or five layer TCP/IP reference model) file sharing protocol and transport layer protocol to provide that shared access. Modern operating systems for personal computers include distributed file systems that support file sharing, while hand-held computing devices sometimes require additional software for shared file access. The most common such file systems and protocols are: A resource pool makes it easier for you to administer people or equipment assigned to tasks in more than one project file. The resource pool centralizes resource information, such as the resource name, calendar used, resource units, and cost rate tables. The "primary operating system" is the operating system on which the file sharing protocol in question is most commonly used. On Microsoft Windows, a network share is provided by the Windows network component "File and Printer Sharing for Microsoft Networks", using Microsoft's SMB (Server Message Block) protocol. Other operating systems might also implement that protocol; for example, Samba is an SMB server running on Unix-like operating systems and some other non-MS-DOS/non-Windows operating systems such as OpenVMS. Samba can be used to create network shares which can be accessed, using SMB, from computers running Microsoft Windows. An alternative approach is a shared disk file system, where each computer has access to the "native" filesystem on a shared disk drive. Shared resource access can also be implemented with Web-based Distributed Authoring and Versioning (WebDAV). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shared resource」の詳細全文を読む スポンサード リンク
