WHAT IS COMPUTER?
Computer is a programmable machine that has been designed for reading
and executing the order of a list of instructions that make it perform
arithmetic and logic operations on binary numbers
WHAT IS COMPUTER ORGANIZATION AND ARCHITECTURE?
Computer architecture is the design of a concept and structure of a
computer despair. This architecture is also a blueprint and a description of
the function and performance of the design requirements for each part of the
computer, especially the way the central processing unit (CPU) to function

1.2 Coputer Component
1.2.1
Choosing Computer Components
v Internal Components
§ Power Supply : the
appropriate voltages for alternating current (AC) to direct current (DC) for
the internal components.
§ Motherboard : all
main component on the electronic coputer is on this centrepieces.
§ Processor/CPU :
normally, it is fixed(come together) with the motherboard. It the computer
brain.
§ RAM : temporarily
store instruction /data for CPU usage.
§ Hard Drive / Hard
Disk : store long term data. The operating system always store here.
§ Graphics/Video Disk
: to provide connection on the coputer monitor.
v External Componentc
§ Keyboard : to type
somethings on
§ Mouse : to scroll
over something
§ Monitor : to make
the output appear.CRT and LCD are the type of monitor

(ROM)
Ø Virtual Memory
v Basic Input /
Output System
·
Is a configuration program that store detail of of the computer hardware
and to boot up the computer. BIOS located at Read Only Memory
