Types of Computers: Individuals and Organisations

Types of computers can be separated into two main categories:

–Computers for individuals are normally designed for one user at a time.

–Computers for organizations are designed to be used by many people at the same time.

Computers for individuals

–Personal computers (PCs) are generally either MAC (Apple’s Macintosh) systems or IBM-compatible systems.

–Notebook computers are small enough for easy computer mobility.

– Sub notebooks have fewer components than traditional notebooks, weigh less, and are smaller.

Computers for organizations

–Tablet PCs can be used to input data with a keyboard or mouse, and the user can write on the monitor with a special pen or stylus.

–Servers enable users connected to a computer network to have access to the network’s programs, hardware, and data.

–Clients include the user computers connected to the network.

–A client/server network includes the use of client computers with centralized servers.

–Minicomputers or mid-range servers are designed to meet the needs of smaller companies or businesses.

–Mainframes carry out very large processing jobs to meet the needs of large companies or agencies of the government.

–Supercomputers are able to perform  extremely high-speed processing and show underlying patterns.
