History of operating systems - History of operating systems This article is part of the History of computing series. History of computing hardware (before 1960s) History of computing hardware (1960s-present) History of operating systems The history of computer operating systems recapitulates to a degree, the recent history of computing. Operating systems provide a set of functions needed and used by most applications, and provide the necessary linkages to control a computer's hardware. Without an operating system, each program would have to have drivers for your video card, sound card, hard drive, and other peripherals.

List of companies operating trains in the United Kingdom - List of companies operating trains in the United Kingdom UK Train Operating Companies Since the privatisation of British Rail, trains on the British railway system are operated by several companies, mainly on the basis of a regional franchises. Tracks and signalling are not operated by the train companies but by Network Rail (which took over from Railtrack in 2002). The exceptions are South Eastern Trains and Translink. South Eastern Trains, which took over from Connex South Eastern, is a wholly-owned subsidary of the Strategic Rail Authority. The SRA hopes to award the franchise to a private operator in 2005. Translink is the Government-owned train company in Northern Ireland, where services were never privatised. At first glance it looks as if a large number of companies are.
Disk operating system - Disk operating system In times when hard disk drives and even floppy disk drives were optional rather than default features of operating systems, being a Disk Operating System (i.e. disk-based or disk-aware) was a mark of distinction. A number of such systems exist; the Commodore 64 and the Apple II home computers each featured a DOS, as did (on the other end of the spectrum) IBM's System/370 and System/390 series of mainframes (DOS/VSE, Disk Operating System/Virtual Storage Extended). The most popular family of operating systems called "DOS" is that running on IBM PCs. The original version was provided to IBM by Microsoft, and marketed as "PC-DOS". Later versions were also sold as "MS-DOS". Digital Research produced a compatible variant known as "DR-DOS", and (after a buyout) "OpenDOS"..
Categorical list of programming languages - Categorical list of programming languages This is a list of programming language grouped by category. See also Alphabetical list of programming languages Chronological list of programming languages Generational list of programming languages Assembly languages directly correspond to a machine language (see below) in order to allow machine code instructions to be written in a form understandable by humans. Assembly languages allow programmers to use symbolic addresses which are later converted to absolute addresses by the assembler. Most assemblers also allow for macros and symbolic constants as well. SSK (Sistema Simvolicheskogo Kodirovaniya, or "System of symbolic coding") for Minsk family of computers. AKI (AvtoKod Ingenera, i.e., "engineer's autocode") for Minsk family of computers was half-step away from assembly languages and doesn't really fit into any other categories in.
CP/M operating system - CP/M operating system CP/M, an acronym for Control Program/Monitor (or Control Program/Microcomputer), was an early operating system for Intel 8080 and Zilog Z80 based microcomputers. It was created by Digital Research, Inc founded by Gary Kildall. The combination of CP/M and S-100 bus computers patterned on the MITS Altair was the first "industry standard", and was widely used through the late 1970s and into the mid-80s. Table of contents showTocToggle("show","hide") 1 Description 2 History 2.1 MS-DOS takes over 3 external links Description CP/M's command line interface, implemented in the CCP command processor, was patterned after the operating systems from Digital Equipment Corporation, such as RSTS/E for the PDP-11. Commands generally took the form of a keyword followed by a list of parameters separated by spaces or special.
Real-time operating system - Real-time operating system A Real Time Operating System or RTOS is an operating system that has been developed for real-time applications. Typically used for embedded applications they usually have the following characteristics: Small footprint (doesn't use much memory) Pre-emptable (any hardware event can cause a task to run) Multi-architecture (code ports to another type of CPU) Many have predictable response-times to electronic events Debate exists about what actually constitutes real-time. Many real-time operating systems have scheduler and hardware driver designs that minimize the periods for which interrupts are disabled, a number sometimes called the interrupt latency. Many also include special forms of memory management that limit the possibility of memory fragmentation, and assure a minimal upper bound on memory allocation and deallocation times. It is a fallacy to.
Operating system - Operating system In computing, an operating system (OS) is the system software responsible for the direct control and management of hardware and basic system operations, as well as running applications such as word processing programs and Web browsers. Colloquially, the term is most often used to mean all the software which "comes with" a computer system before any applications are installed. The operating system ensures that other applications are able to use memory, input and output devices and have access to the file system. If multiple applications are running, the operating system schedules these such that all processes have sufficient processor time where possible and do not interfere with each other. At the beginning of 2004, there were essentially two major families of operating system in.
List of computer scientists - List of computer scientists This is a list of computer scientists, people who do work in computer science, in particular researchers and authors. Some persons notable as programmers are included here because they work in research as well as program. A few of these people pre-date the invention of the digital computer; they are now regarded as computer scientists because their work can be seen as leading to the invention of the computer. Others are mathematicians whose work falls within what would now be called theoretical computer science, such as complexity theory and algorithmic information theory.
