Information technology (IT) is a set of related fields within information and communications technology (ICT), that encompass computer systems, software, programming languages, data and information processing, and storage. [1] Information technology is an application of computer science and computer engineering.
The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems such as Sabre. [ 140 ] In the 1970s, computer engineers at research institutions throughout the United States began to link their computers together using telecommunications technology.
In some cases, hobby development is in support of a "homebrew" computing device, for example, a simple single-board computer powered by a 6502 microprocessor. Or, development may be for an architecture already in widespread use. Operating system development may come from entirely new concepts, or may commence by modeling an existing operating ...
Operating systems are "the layer of software that manages a computer's resources for its users and their applications". [9] There are three main purposes that an operating system fulfills: [10] Allocating resources between different applications, deciding when they will receive central processing unit (CPU) time or space in memory.
