Computer fileA computer file is a named collection of data treated as a unit by the system that manages it. Today, this system is called a file system. Many older computer systems lacked a distinct file system per se, yet a management feature is required in order to provide a file abstraction. Files can be shared with and transferred between computers and mobile devices via removable media, networks, or the Internet. Different types of computer files are designed for different purposes.
Operating systemAn operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other resources.
Microsoft WindowsComputer operating systemOperating systemWindows is a proprietaryoperating system developed by Microsoft. Windows is grouped into families that cater to particular sectors of the computing industry – Windows for personal computers, Windows Server for servers, and Windows IoT for embedded systems.File systemIn computing, a file system or filesystem (FS or fs) governs file organization and access. A local file system is a capability of an operating system that services the applications running on the same computer. A distributed file system is a protocol that provides file access between networked computers. A file system provides a data storageservice that allows applications to share mass storage.
Unix-likeA Unix-likeoperating system (sometimes referred to as a UN*X,*nix or *NIX) is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like application is one that behaves like the corresponding Unix command or shell.Data storageData storage is the recording (storing) of information (data) in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media. Biological molecules such as RNA and DNA are considered by some as data storage. Recording may be accomplished with virtually any form of energy. Electronic data storage requires electrical power to store and retrieve data.
CP/MDiscontinued family of computer operating systemsOperating systemCP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080-based microcomputers by Gary Kildall of Digital Research, Inc. CP/M is a disk operating system and its purpose is to organize files on a magnetic storage medium, and to load and run programs stored on a disk.
End-of-fileIn computing, end-of-file (EOF) is a condition in a computer operating system where no more data can be read from a data source. The data source is usually called a file or stream. DetailsIn the C standard library, the character-reading functions such as getchar return a value equal to the symbolic value (macro) EOF to indicate that an end-of-file condition has occurred.
Line (text file)In computing, a line is a unit of organization for text files. A line consists of a sequence of zero or more characters, usually displayed within a single horizontal sequence. The term comes directly from physical printing, where a line of text is a horizontal row of characters. Depending on the file system or operating system being used the number of characters on a line may either be predetermined or fixed, or the length may vary from line to line.
MulticsMultics ("Multiplexed Information and Computing Service") is an influential early time-sharingoperating system based on the concept of a single-level memory. It has been written that Multics "has influenced all modern operating systems since, from microcomputers to mainframes." Initial planning and development for Multics started in 1964, in Cambridge, Massachusetts.
DOSDOS (, ) is a family of disk-based operating systems for IBM PC compatible computers. It primarily consists of IBM PC DOS and a rebranded version, Microsoft's MS-DOS, both of which were introduced in 1981. Later, compatible systems from other manufacturers are DR-DOS (1988), ROM-DOS (1989), PTS-DOS (1993), and FreeDOS (1994). MS-DOS dominated the IBM PC compatible market between 1981 and 1995.E-texte-text (from "electronic text"; sometimes written as etext) is a general term for any document that is read in digital form, and especially a document that is mainly text. For example, a computer-based book of art with minimal text, or a set of photographs or scans of pages, would not usually be called an "e-text". An e-text may be a binary or a plain text file, viewed with any open source or proprietary software.*As an Amazon Associate I earn from qualifying purchases.
