KEY INFORMATION SECTION 3

Types of computer systems

Computers can be divided into different types, depending on their size and power. There is an increasing variety of computers of different sizes and designed for different purposes.

Mainframe computers are the largest and most powerful. They can handle large amounts of information very quickly supporting multiple users at the same time and can support more simultaneous processes than a PC. A terminal, consisting of a keyboard and a monitor, is used

powerful, expensive computers that are operated by a team of professionals and are used for large-scale computing purposes in banks, big companies and in large institutions like universities or government departments. The most powerful mainframes are called supercomputers.

The most common type of computer is the microcomputer, sometimes called personal computer. It gets the name from the tiny electronic device, called the microprocessor that does the actual processing. A PC is a computer designed to meet the needs of a single person. It is used by an individual, usually in an interactive mode. PCs are found in many businesses and are popular for

equipped with software to handle e-mail and surf the Web via wireless technology, without cables. You can hear popular MP3 music or record your ideas through its built-in voice recorder. Once at home you can synchronise data with your desktop PC. PDAs support mobile computing, but almost never run any desktop software. They can be used as cellphones or as personal organizers for storing notes, reminders and addresses.

A wearable computer runs on batteries and is worn on the user's body, e.g. on a belt, backpack or vest; it is designed for mobile or hands-free operation, often incorporating a microphone and a head-mounted display. Some devices are equipped with a wireless modem, a keypad and a small screen; others are voice-activated, worn like a scarf and can access

email or voice mail. Wearable computers are especially useful for applications that require computational support while the user's hands, voice, eyes or attention are actively engaged with the physical environment. Users of wearable technology consider themselves 'cyborgs'. This term comes from 'cybernetic organism', referring to a being that is part robot, part human.
