what does it mean in computers

In the context of computers, Information Technology (IT) refers to the use and management of computing technology in businesses and other organizations. IT encompasses several layers of physical equipment, virtualization, management systems, automation tools, operating systems, other system software, and applications used to perform essential functions. A computer, on the other hand, is a machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern digital electronic computers can perform generic sets of operations known as programs, which enable them to perform a wide range of tasks. In addition to accepting data, processing it, and producing outputs, computers can also store data for later use in appropriate storage devices and retrieve it whenever necessary. Peripherals are devices that provide input or output to the computer, such as the keyboard, mouse, display, printer, hard disk drives, floppy disk drives, and optical disc drives. Finally, symbols are used in many programs to represent different functions, such as the floppy disk symbol representing the save feature.
