Encyclopedia > File server

In telecommunication, the term file server has the following meanings: Image File history File links Circle-question-red. ... Copy of the original phone of Graham Bell at the Musée des Arts et Métiers in Paris Telecommunication is the transmission of signals over a distance for the purpose of communication. ...

  • A form of disk storage that hosts files within a network; file servers do not need to be high-end but must have enough disk space to incorporate a large amount of data. Many people mistake file servers for a high-end storage system, but in reality, file servers do not need to possess great power or super fast computer specifications.
  • A computer program, that allows different programs, running on other computers, to access the files of that computer
  • In common parlance, the term file server refers specifically to a computer on which a user can map or mount a drive or directory so that the directory appears to be on the machine at which the user is sitting. Additionally, on this type of file server, the user can read or write a file as though it were part of the file system of the user's computer.

Files and directories on the remote computer are usually accessed using a particular protocol, such as WebDAV, SMB, CIFS, NFS, Appletalk or their mutations. A computer program is a collection of instructions that describe a task, or set of tasks, to be carried out by a computer. ... For other uses, see Map (disambiguation). ... Mounting, in computer science, is the process of making a file system ready for use by the operating system, typically by reading certain index data structures from storage into memory ahead of time. ... Look up Drive in Wiktionary, the free dictionary. ... In computing, a directory, catalog, or folder, is an entity in a file system which can contain a group of files and/or other directories. ... For other senses of this word, see protocol. ... WebDAV is an IETF working group. ... Server Message Block (SMB) is an application-level network protocol mainly applied to shared access to files, printers, serial ports, and miscellaneous communications between nodes on a network. ... Server message block (SMB) is a network protocol mainly applied to share files, printers, serial ports, and miscellaneous communications between nodes on a network. ... Network File System (NFS), a protocol originally developed by Sun Microsystems in 1984 and defined in RFCs 1094, 1813, and 3530 (obsoletes 3010) as a distributed file system, allows a user on a client computer to access files over a network as easily as if attached to its local disks. ... AppleTalk is a proprietary suite of protocols developed by Apple Computer for computer networking. ...

  • Although files can be sent to and received from most other computers unless their primary function is access by the above means, they are generally not considered file servers as such.

Memory requirements

File servers have historically been instrumental in pushing up the demand for RAM.[dubious ] The Novell NetWare file server operating system, which dominated the market for file servers at the time of greatest growth in demand, read the entire FAT table into RAM on boot,[dubious ] enabling rapid access to files. Whilst this guaranteed maximum performance, it also required large quantities of memory. Random access memory (usually known by its acronym, RAM) is a type of data store used in computers. ... NetWare is a network operating system developed by Novell, Inc. ... An operating system (OS) is a computer program that manages the hardware and software resources of a computer. ... File Allocation Table (FAT) is a partially patented file system developed by Microsoft for MS-DOS and is the primary file system for consumer versions of Microsoft Windows up to and including Windows Me. ...


This in turn drove demand for Uninterruptible Power Supply (UPS) devices as it became more apparent that power outages could cause loss of data. An uninterruptible power supply (UPS), uninterruptible power source or sometimes called a battery backup is a device which maintains a continuous supply of electric power to connected equipment by supplying power from a separate source when utility power is not available. ...


This has become less of an issue in recent years with journaling file systems. A journaling (or journalling) file system is a file system that logs changes to a journal (usually a circular log in a specially-allocated area) before actually writing them to the main file system. ...


File and print

Traditionally, file and print services have been combined on the same computers due to similar computing requirements for both functions.[dubious ] Usually, such computers are distinct from application and database servers, which have different, usually more processor-intensive, requirements. However, as computing power increases and file serving requirements remain relatively constant, it is more common to see these functions combined on the same machine.


Security

File servers generally offer some form of system security to limit access to files to specific users or groups. In large organizations, this is a task usually delegated to what is known as directory services such as Novell's NDS or Microsoft's Active Directory. A Directory service organizes content in a directory server into a logical and accessible structure. ... Novell eDirectory (formerly called Novell Directory Services) is an X.500 compatible directory service software product released in 1993 by Novell, Inc. ... Typically Active Directory is managed using the graphical Microsoft Management Console. ...


These servers work within the hierarchical computing environment which treat users, directories, computers, applications and files as distinct but related entities on the network and grant access based on user or group credentials. In many cases, the directory service spans many file servers, potentially hundreds for large organizations. In the past, and in smaller organizations, authentication can take place directly to the server itself.
