fax machine
video conferencing
telegraph

6. list 3 types of computer

analog - process physical data
digital - process data in binary
hybrid - combination of analog and digital computer

7. what is category of computer and describe it

mainframe - larges catogory of computer used for major business processing
midrange - middle size computer capable of suporting the computing needs of small organization or of managing networks of other computers
minicomputer - middle range computers used in Universities, factories and research laboratories as server to manage organization computer network.

8. gives 3 basic function of software

manange computer system's data sources
create plateforms and tools to used the data source
act as the " middle man" between human and data source storage

9. explain 3 main system software in short

operating systems - manage and control the computer's activities
computer language translation programs - convert programming languages into machine language
utility programs - common processing tasks.

Chapter 2: Input output devices and computer hardware

1. define an input devices and output devices

insput device captures data and sends it to a computer system
input device convert physical movement such as key pressing or environmental data such as temperature, sound or light into electrical signal

2.describe 3 basic type of mouse

mechanical - has a rubber or metal ball on itss underside that can roll in all directions
opt mechanical - same as mechanical but uses optical sensors to direct motion of the ball
optical - uses laser to detect the mouse moment. they responses more quickly and precisely than mechanically and opt mechanical mouse
