SUPERCOMPUTER

- A computer that led theworld in terms ofprocessing capacity,particularly the speed ofcalculation

- It was use to solveproblems involving bymajor universities,military agencies andscientific researchlaboratories


5/17

MAINFRAME

Its designed to handle veryhigh volume input andoutput (I/O) and emphasize

throughout computing. It is used mainly by large

organizations for criticalapplication, typically bulkdata processing, industry

and consumer statistic andfinancial transactionprocessing.


6/17

Mini computer

It is a midsizedcomputer

It is and old term for aclass of multi-usercomputers, lies betweenthe largest multi-usersystems (mainframecomputer) and thesmallest single-usersystem (microcomputeror personal computer)


7/17

MICROCOMPUTER

Small desktop or portablecomputer, typically designedto be used by one person at

a time, although individualcomputers can be linked in anetwork so that users canshare data and programmes

Microcomputers are the

smallest of the four classesof computer


8/17

WORKSTATION

A type of computer usedfor engineering

application, desktoppublishing, softwaredevelopment and othertypes of application thatrequire a moderate

amount of computingpower and relatively highquality graphicscapabilities.

PALMTOP More commonly known as Personal

Digital Assistants (PDAs)

Use flash memory instead of a harddrive for storage

Do not have keyboards but rely on

touchscreen technology for user input A slightly larger and heavier version of

the palmtop is the handheld computer


14/17

SERVER

A computer that have been optimized toprovide services to other computersover a network

Servers usually have powerfulprocessors, large memory and harddrives
