INTRODUCTION
1.1
BACKGROUND OF STUDY
Desktop
computer is frequently used in our today’s society. It is composed of parts
like monitor, mouse, keyboard and system unit.
The computer box itself known as
system unit is also called cabinet or chassis. It is the container that houses
other components such as motherboard, RAM, interface or add-on cards, switch
mode, power supply, drives, ports etc.
A
good knowledge of how the computer is made up, will enable one to use it more
effectively. Most people thought the system box to be the CPU, but a good
understanding will help users to know it better. It is only when all the
necessary components are assembled together that we can get a computer system.
Having a good knowledge of the hardware components or parts of the system unit
or chassis or box will enable the user to replace it when any of them breaks
down. To understand, identify and know the basic hardware parts of the system
unit is the purpose of this project.
It is good for one to understand that
inside the system box, there are components that are connected together which
make up the computer. Different kinds of parts for connecting external devices
are found outside the system casing. Open bays are for connecting optical
devices such as DVD and CD-Rom drive are also found on the front side. A small
button is found near the drives door which can be pressed to eject the tray
where you can place the CD or DVD disc. Same button can also be pressed to
take-in the tray. It can also be operated from the system’s windows operating
system. In some cases USB port is also found at the front of the
casing which allows your flash drives, printers, Ipod, Ipads, Iphones and
external plug and play USB devices to be connected into your computer. At the
front panel one can also see ports for camera, memory media reader. Here you
can slot in your memory card containing your memory storage removed from the
camera or the phone and you insert it into the computer so that the image
stored on it can be accessible.
The
rear-part of the system unit box are other connectors like parallel
port for printers, more USB ports, PS/2 ports for mouse, keyboard,
serial ports and others.
These ports are used for connection of
the peripheral devices (i.e. the non-essential parts of the computer).
These peripherals include external
devices like monitors, speakers, micro-phones etc. At the rear is also found
the Ethernet (NIC) port for connecting the computer to the network.
When you open the system unit casing
by unscrewing, you will see some individual components connected via cables or
plugged directly into large board attached to the side of the casing. This
board is the motherboard and is used to connect all the individual devices
inside the computer box. The power supply unit also provides power supply to
these components as they are connected to it.
The memory (RAM) and the
microprocessor is also seated fixed on the motherboard. The interface or add-on
cards are also connected as they communicate with the board where it is
properly fixed.
1.2 AIMS
AND OBJECTIVE
The
aims and objectives of this project work is to put down the plans and procedure
for assembling a desktop computer system that is functional and can satisfy the
need of a high configuration system. It should be purchased component by
components e.g. the casing, motherboard, RAM, processor, power supply unit, the
drives etc and be coupled together.
Nevertheless,
the major part of this project is planning what you are going to buy and how
you can build them up into a functional computer system.
1.3 JUSTIFICATION
OF THE PROJECT
Computer
system is an intricate machine as a result, many a times it is proved difficult
to explain to the undergraduates of higher institution. So this project is a
better idea of solving the problem. The knowledge acquired on the course of
this work will enable the students understand better what the computer is, in
this computer age. Carrying out such project will also overcome the
barrier/limitation facing Nigeria undergraduate on the knowledge of
computer. This will also help many Nigerians to be ICT compliance.
1.4: SCOPE
OF THE PROJECT
This
project’s scope covers all areas including identifying components/parts of the
computer system, purchasing them and assembling them together into a functional
computer system.
It
also involves replacing any damaged parts during breakdown. Servicing and
maintenance of the computer system is not excluded.
Furthermore, knowledge for hardware
upgrading and software installation and upgrading is also not exempted in this
scope. By this project a proficient computer technician emerges.
1.5: LIMITATION
OF THE STUDY
One
of the challenges I encountered during this project research was the scarcity
of/unavailability of some components in the market. Nevertheless, some of these
components are exorbitant even when you see them in the market.
Further limiting factors that I encountered
are explained below:
(a). TIME
CONSTRAINT: The time to carry out this project is short such a research cannot
be completed in a semester let alone this few weeks. Researching at the library
needs time.
(b). FINANCIAL
CONSTRAINT: As a student, I was not financially buoyant. I was affected because
there was not enough money to buy components, browse the internet, pay and
gather other researching materials that will certify this project a research
work.
Nevertheless,
the work added to my academic work load in the campus, serving as a great
constraint, yet all these could not hamper the research work.
However, the project, Assembly of
desktop computer system has sub-units such as
(1). The system
casing
(2). The
motherboard
(3). The
Central Processing Unit (CPU).
(4). The
drivers
(5). The
Input/output Unit.
(6). The
Software.
1.6 DEFINITION
OF TERMS
1. COMPUTER:
A computer is a programmable machine which can accept data as input, process
data, store data and generate output as information which helps the user in
quick decision making. The main components of digital computer include CPU
(Central Processing Unit), memory, input/output devices etc.
2. Central
Processing Unit (CPU): The CPU is the brain of the computer. It executes user
programs and controls memory and input /output devices.
3. Hard
Disk drive (HDD): It is the main storage device used for storing data and
information as well as computer programs. This information can be retrieved by
the user at will. The hard drive is made up of a rotating disk that is coated
with magnetic material.
1.7 PROJECT
REPORT ORGANIZATION
Six
Chapters were covered in the course of the design and development of this
project work. The Chapters and their contents are as follows:
Chapter One is the introductory
chapter that gives the aims/objective, scope, limitations, justification for
the project, etc.
Chapter Two contains the Literature
Review. It contains the different related works done by several authors with
dates. It also states the discussions on some limitations encountered while
carrying out this research work.
Chapter Three discussed in details the
practical system analysis based on what the desktop computer system will do
when fully constructed/assembled and installed. It also states the concept of
analysis, requirement analysis, and procedure for the design analysis.
Chapter Four discussed about the
design/preliminary design of how the system will achieve its function. Software
installation, design and implementation was also discussed.
Chapter Five states the references,
evaluation and cost analysis.
Chapter Six contains the summary of
