A mid-1970s science fiction novel by David Gerrold, When H.A.R.L.I.E. was One, includes a description of a fictional computer program named VIRUS that worked just like a virus (and was countered by a program named ANTIBODY). The term "computer virus" also appears in the comic book "Uncanny X-Men" No. 158, published in 1982. A computer virus's ...
The Linux operating system is based on this kernel and deployed on both traditional computer systems such as personal computers and servers, usually in the form of Linux distributions (including Ubuntu and its derivatives), and on various embedded devices such as routers, wireless access points, PBXes, set-top boxes, FTA receivers, smart TVs ...
Ubuntu (/ ʊ ˈ b ʊ n t uː / ⓘ uu-BUUN-too) [8] is a Linux distribution derived from Debian and composed mostly of free and open-source software. [9] [10] [11] Ubuntu is officially released in multiple editions: Desktop, [12] Server, [13] and Core [14] for Internet of things devices [15] and robots.
On a network, such a device is called a host. In addition to server, the words serve and service (as verb and as noun respectively) are frequently used, though servicer and servant are not. [a] The word service (noun) may refer to the abstract form of functionality, e.g. Web service.
Linux is one of the most prominent examples of free and open-source software collaboration. While originally developed for x86 based personal computers, it has since been ported to more platforms than any other operating system, [30] and is used on a wide variety of devices including PCs, workstations, mainframes and embedded systems.
On embedded devices, Linux is typically held in the device's firmware and may or may not be consumer-accessible. Anaconda, one of the more popular installers, is used by Red Hat Enterprise Linux, Fedora (which uses the Fedora Media Writer) and other distributions to simplify the installation process. Debian, Ubuntu and many others use Debian ...
Linus Torvalds in 2002. In 1991, while studying computer science at University of Helsinki, Linus Torvalds began a project that later became the Linux kernel.He wrote the program specifically for the hardware he was using and independent of an operating system because he wanted to use the functions of his new PC with an 80386 processor.
The origins of Unix date back to the mid-1960s when the Massachusetts Institute of Technology, Bell Labs, and General Electric were developing Multics, a time-sharing operating system for the GE 645 mainframe computer. [21] Multics featured several innovations, but also presented severe problems. Frustrated by the size and complexity of Multics ...
