Introduction
• Computer Assembly Is An
Essential Job Of A Computer
Installation Technician.
• Computer Assembly Is A
Process In Which All The
Internal Components
Required For The Computer
System Are Fitted So As To
Make The Computer
Functional.
• There Is A Proper Sequence
Of Attachment Of Each And
Every Component Into The
Computer System.

Processor & Motherboard:
• The Motherboard Has To Be Prepared Before Its
Installation. To Prepare The Motherboard, You First Need
To Install The CPU, Then The Heat Sink On The CPU And
CPU Fan.

Memory
• There are two types of memory.
Memory
Volatile Memory Non - Volatile Memory

10. 6/29/2024
RAM: (Random Access Memory)

11. 6/29/2024
Types of RAM:
RAM
Static RAM Dynamic RAM
• Static ram:-
• These memories have the property that their contents are
retained as long as the power is kept on.
• Static ram doesn't require any refreshing circuit.
• It is faster than dynamic but dynamic memory is cheaper
than static.
• Dynamic ram:-
• Information stored has to be periodically refreshed using
external circuit.

ROM:
• A memory in which data is permanently written. The
data can be read quickly but not changed.
• Once the data has been written onto a ROM chip, it
can’t be removed and can only be read.
• Unlike the RAM, ROM retains its contents even when
the computer is turned off.

13. 6/29/2024
Types of ROM:
ROM
PROM EPROM
A PROM is
memory chip on
which data can
be written only
once.
EEPROM
It is a special
type of memory
that retains its
content until it
is not erased.
It is a special
type of PROM
that can be
erased by
exposing it to
an electrical
charge.
It is similar to
flash memory.

HDD: (Hard Disk)

15. 6/29/2024
SSD: (Solid State Drive)
An SSD, or solid-state drive, is a type of storage device
used in computers. This non-volatile storage media
stores persistent data on solid-state flash memory.

Graphic Card:
video card, also called graphics card, integrated circuit that
generates the video signal sent to a computer display. The
card is usually located on the computer motherboard or is
a separate circuit board but is sometimes built into the
computer display unit.

18. 6/29/2024
LAN Card:
A network card, network adapter, LAN Adapter or NIC
(network interface card) is a piece of computer hardware
designed to allow computers to communicate over a
computer network.

19. 6/29/2024
Sound Card:
A sound card is a computer
component responsible for
generating and recording
audio. It enables users to
connect analog speakers,
headphones and
microphones to their
computer. Most modern
computers have a built-in
sound card in the
motherboard.
