Hardware - Basics

The main components of information systems are computer hardware and software, databases, telecommunications systems, human resources, and procedures.

Today even the smallest firms, as well as many households, own or lease computers. These are usually microcomputers, also called personal computers. Large organizations typically employ multiple computer systems, from a few powerful mainframe machines (or even more powerful supercomputers) and minicomputers to widely deployed personal computers.

Together with computer peripheral equipment, such as
  • magnetic disks,
  • input-output devices, &
  • telecommunications gear,

    these constitute the hardware of information systems. The cost of hardware has steadily and rapidly decreased, while processing speed and storage capacity have increased vastly.
