2. Memory (RAM and ROM)
3. Input / Output.

Where is the CPU / Processor, Memory and I / O Port is located (installed) on the Mother
Board, will be specified later parts of the computer is:
1. Central Processing Unit / Processor
The main part of the computer because the processor function to regulate all activities
existing on the computer. The speed of the processor units are MHz (Mega Hertz) or GHz (1000
Megahertz), where the greater the value the faster the process of execution on the computer.

2. Memory
Memory function for storing data and programs. Various types of memory is the fastest
access until late. Based on the access speed of the memory hierarchy can be made
as in table 1.1. follows.

VII. Installing Connector for Panel on Chasing
1. Place the connector carefully and to the front panel Chasing.
2. Position pin / ft depending on motherboard connector (see the manual MB or notice
data is written around the motherboard)









VIII. Installing Power Suplly for Motherboards
