The last 8-bit version of CP/M was version 3, often called CP/M Plus, released in 1983. Its BDOS was designed by Brown. It incorporated the bank switching memory management of MP/M in a single-user single-task operating system compatible with CP/M 2.2 applications. CP/M 3 could therefore use more than 64 KB of memory on an 8080 or Z80 processor.

GEM (for Graphics Environment Manager) is an operating environment which was created by Digital Research (DRI) since 1984 for use with the DOS operating system on Intel 8088 and Motorola 68000 microprocessors.. GEM is known primarily as the graphical user interface (GUI) for the Atari ST series of computers, and was also supplied with a series of IBM PC-compatible …

This is a list of operating systems.Computer operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. Criteria for inclusion is notability, as shown either through an existing Wikipedia article or citation to a reliable source.

El sistema operatiu és el conjunt dels diferents programes que controlen el funcionament d'un ordinador.Les seves funcions, entre d'altres, consisteixen a gestionar les transferències d'informació internes, procurar la comunicació de l'ordinador amb els operadors, controlar l'execució dels programes amb la detecció dels errors, encadenar automàticament les feines, …

Unter dem Begriff BIOS (IPA: [ˈbaɪɔs], Aussprache? / i, von englisch basic input/output system) wird im Allgemeinen die Firmware eines Personal Computer verstanden („PC-Firmware“), die beim Kaltstart des Computers durch Bootstrapping das Starten weiterer Software, wie des Betriebssystems, ermöglicht.Die Übereinstimmung dieses Akronyms mit dem altgriechischen …

DR-DOS (written as DR DOS, without a hyphen, in versions up to and including 6.0) is a disk operating system for IBM PC compatibles.Upon its introduction in 1988, it was the first DOS attempting to be compatible with IBM PC DOS and MS-DOS (which were the same product sold under different names).. DR-DOS was developed by Gary A. Kildall's Digital Research and …

Other time measurements. Closely related to system time is process time, which is a count of the total CPU time consumed by an executing process.It may be split into user and system CPU time, representing the time spent executing user code and system kernel code, respectively. Process times are a tally of CPU instructions or clock cycles and generally have no direct correlation to …

Technical overview. The name of the file system originates from the file system's prominent usage of an index table, the File Allocation Table, statically allocated at the time of formatting.The table contains entries for each cluster, a contiguous area of disk storage.Each entry contains either the number of the next cluster in the file, or else a marker indicating end of file, unused disk ...

In computer data storage, drive letter assignment is the process of assigning alphabetical identifiers to volumes.Unlike the concept of UNIX mount points, where volumes are named and located arbitrarily in a single hierarchical namespace, drive letter assignment allows multiple highest-level namespaces.Drive letter assignment is thus a process of using letters to name …

Het acroniem DOS staat voor disk operating system, oftewel een besturingssysteem voor apparaten met schijfstations (diskdrives). Bij de opkomst van computers met diskette was het handig om na de opstartcyclus (boot-strap) een commando-processor en hulpprogramma's te laden.. Geschiedenis. In 1973 schreef Gary Kildall in de programmeertaal PL/M een van de …
