3 Computer Hardware SUMMARY Computer Systems. Major types of computer systems are summarized in Figure 3.3. Microcomputers are used as personal computers, network computers, personal digital assistants, technical workstations, and information appliances. Midrange systems are increasingly used as powerful network servers and for many multiuser business data processing and scientific applications. Mainframe computers are larger and more powerful than most midsize systems. They are usually faster, have more memory capacity, and can support more network users and peripheral devices. They are designed to handle the information processing needs of large organizations with high volumes of transaction processing or with complex computational

Unformatted text preview: problems. Supercomputers are a special category of extremely powerful mainframe computer systems designed for massive computational assignments. • The Computer Systems Concept. A computer is a system of information processing components that perform input, processing, output, storage, and control functions. Its hardware components include input and output devices, a central processing unit (CPU), and primary and secondary storage devices. The major functions and hardware in a computer system are summarized in Figure 3.10. • Peripheral Devices. Refer to Figures 3.14 and 3.22 to review the capabilities of peripheral devices for input, output, and storage discussed in this chapter....
