Limited-capacity memory, high speed is
more expensive than main
memory. Cache memory is there between mai
n memory and processor registers, so
that processors do not work directly referring to
the main memory so that performance can be
improved. Cache Memory There are two kinds:
• Cache Memory which is located on
the internal processor, cachememory
of this type of very high-speed access
• Chace Memory, which are outside of
the processor, which is locatedon
the motherboard.

• ROM (Read Only Memory) is memory that can
only read data orprogram. On your
PC, ROM contained in the BIOS
(Basic InputOutput System) is located
on Mother Board which functions forsetting
the peripherals available on
the system. Chace Memory,located outside
the processor, which is located on
the motherboard
• RAM (Random Access Memory) which has
the capacity for conversion of
data or programs stored on it.

12. Input / Output Unit is part of the computer to receive data and display the
data after processing by the processor. Input / Output unit is divided into
two parts, namely:
1. Port I/O
2. Peripheral I/O

14. • The first category consists of equipment that perform input and output
operations, this category includes the keyboard, trackball, mouse,
printers, and video display.
• The second category consists of equipment in priority to the
secondary data storage, where storage is mainly provided by the
computer's main memory.

Peripherals is something that refers to the external equipment is
connected to a computer. Computer peripherals can be divided into
two categories based on function.

The printer is
an output component is classified as
a Hard Copy Device. Which is a device
used to print the output of the process
performed by the computer either text
or graphics directly using paper
or other media.

the ribbon to form characters on the print media.
• Inkjet Printers, How it works, with a squirt of liquid ink onto paper.
• Laser Printers, printers for computers that
use light diode technology to obtainsmall particles of toner cartridge to
the paper. This printer has a high speed.

21. CPU (Central Processing Unit) or Processor
Processor / CPU (Central Processing Unit) is a computer brain. Processor can be
classified from differences in the amount of data bus. Example there is an 8
bit processor, it means the processor has 8 data bus, processing speed and
the number of cores you have. There are several processors to PC manufacturers,
like Intel, AMD, Cyrix, and IDT Winchip.

22. MOTHERBOARD
The motherboard is a board where all the devices installed startingfrom
the processor, memory, expansion slots, etc.. That should be considered in
selecting or assembling a computer is that every motherboard has different
specifications for each brand or type that is:
• Processor Socket
• RAM Capacity and how many slot ready
• PCI Slot
• Is Support for AGP motherboard for VGA card, AGP support will be
more profitable to stock if desired increase in graphics capabilitiesof computers by
installing a AGP card.
•Chipset
•adapter card is available onboard

24. MEMORY
RAM
ROM
Random Access Memory
In accessing data stored in memory is done
by random (Random)rather
than sequential manner (sequential) as in
the streamer. This means for accessing
the memory elements located anywhere within
the module, will be accessed in the same time.
Based on the manufacture, RAM classified
into two main parts,namely:
• Static RAM
• Dynamic RAM

25. MEMORY
ROM
RAM
Read Only Memory
Data is written in the memory can not be
changed with the normal process and can only
be read only. It is stored in the BIOS when the
computer starts and the first steps is known
as bootstrapping. This type of ROM include:
• PROM (Programmable ROM)
• EPROM (Erasable Programmable ROM)
• EEPROM (Electrically Erasable PROM)

26. CHASING and POWER SUPPLY
CASING
The casing is a box which contain the
processor chip (CPU),memory chip, and c
omes with a motherboard and power
supply. Somet imes
the casing also contains
a secondary storage device.
Casings found on
the computer desktop or tower models. Th
e casing contains the power
supply and fan to prevent excessive arrow

27. CHASING and POWER SUPPLY
CASING
used as a tool to convert AC to
DC current so that the computer can work.
Owned power capacity power supply to
determine the ability of the peripherals can
be connected to the computer. Selection
of anappropriate power supply is
also very necessary to get the maximumper

Current and voltage measurement is only performed if
the components used is the
old component is still unknown whether or not
AVO meter should not use if the motherboard is
still good, because you do not know where
the points are a point of measurement.
Carelessness in this regard could lead to deadly
consequences.
If you already know the power
source voltage of the power supplylook at the

warning sound signal that is not correct installation guidelines. Check
and place it properly.
• AGP VGA Card Installation or less toned or fit, a good motherboard
will give a warning sound signal. Check and place it correctly.
• Disk Data Cabling for that does not fit or reversed. Or setting position
of the Master or Slave Disk incorrect. Correct and check the
jumper position Disk for Master / Slave and check with auto detect Disk in
the BIOS.
• Installation of incorrect connector panel so that the indicator lights
for Disk and Power, is not active. Correct.
