5. TERMS
 USER = A person that communicates with a
computer or uses the information it generates.
 DATA = A collection of unorganized facts (words,
numbers, images, and sounds).
 INFORMATION = Data that is organized, has
meaning, and is useful. Computers manipulate
and process data to create information.
 HARDWARE = The electric, electronic, and
mechanical equipment that makes up a
computer.
 SOFTWARE = The series of instruction that tells
the hardware how to perform tasks.

COMPUTERS
 Similar to conventional PCs
 The addition of a performance-oriented video
card
 Capable of playing computationally demanding
video games
 Needs high technical specification such as high
speed of memory, processor and graphic card.

11. MULTIMEDIA EDITING COMPUTER
 A high specification computer
 Capable of creating and editing digital media files
such as photo, music and videos
 High speed of processor, memory and graphic
card
 Some needs dual monitor and high quality of
sound card

12. APPLICATION SERVER
 Handles all application operations between users
and an organization's backend business
applications or databases
 An application server has to have built-in
redundancy, monitor for high-availability, high-
performance distributed application services and
support for complex database access
 high speed of processor, high speed of memory
and high capacity of hard disk drive. The entire
component must be suitable for a server.
