Computing Hardware Computing hardware evolved from machines that needed separate manual action to perform each arithmetic operation‚ to punched card machines‚ and then to stored-program computers. The history of stored-program computers relates first to computer architecture‚ that is‚ the organization of the units to perform input and output‚ to store data and to operate as an integrated mechanism. Before the development of the general-purpose computer‚ most calculations were done by humans. Mechanical

Windows and other operating systems support both wired and wireless network adapters through a piece of software called a device driver. Network drivers allow application software to communicate with the adapter hardware. Network device drivers are often installed automatically when adapter hardware is first powered on. Finally‚ some network adapters are purely software packages that simulate the functions of a network card. These so-called virtual adapters are especially common in virtual private
