ABSTRACT
The aim of this research work was to disassemble a
computer system and assemble all the various components back into a computer
system; with the objectives of this research work to identify all the various
components of a computer system, to examine the importance of each components
in the computer system, and to carryout the assembling and dissembling of a
computer system. According to this research work assembling a computer system means connecting different components of a
computer so that users can use the computer. Findings of the study show the
processes of carrying out the disassembling of a computer system which include unplugging
the AC power supply to the PC from the wall socket, disconnecting the CPU from
the other devices including the monitor, removing the Cover or chassis or case
of the CPU, unplugging bus cables and ATX power cables of the CPU, removing
Adapter Cards if any, removing the processor and fan, removing the hard disk
and CD/ DVD drives, removing the Memory Modules and the Power Supply (SMPS),
and finally removing the Motherboard. Also findings shows the assembling
processes of a computer system and this includes preparing the CPU case at
first, installing the motherboard, processor, processor heat sink, RAM, SMPS, HDD,
CD/DVD drive, connect expansion cards, SYS/Rear cooling fan, bus cable
connection, power cable connection and the front panel connector connection.
The study therefore concluded that assembling and disassembling a computer
system is not a difficult task but requires keen observation and knowledge of
the different components of the system, once there is a good knowledge to
assemble and disassemble a computer system. It was then recommended that when
choosing a system with a specific processor, a lower power consumption system
is more appropriate; also, the operating system must be well considered by
consulting an expert before deciding which one to go for.

CHAPTER ONE
INTRODUCTION
1.1 Background
of Project
A computer can
be said to be a machine that can be instructed to carry out sequences of
arithmetic or logical operations automatically via computer programming.
Computers have the ability to follow generalized sets of operations, called
programs. These programs enable computers to perform an extremely wide range of
tasks. Early computers were only
considered as calculating devices. Since ancient times, simple manual devices
like the abacus aided people in doing calculations (Wikipedia contributors, 2021).
According to
the Oxford English Dictionary, the first known use of the word
"computer" was in 1613 in a book called The Yong Mans Gleanings by
English writer Richard Braithwait: "I haue [sic] read the truest computer
of Times, and the best Arithmetician that euer [sic] breathed, and he reduceth
thy dayes into a short number." This usage of the term referred to a human
computer, a person who carried out calculations or computations. The word
continued with the same meaning until the middle of the 20th century. During
the latter part of this period women were often hired as computers because they
could be paid less than their male counterparts (Evans, 2018). By 1943, most
human computers were women (Smith, 2013). More sophisticated electrical
machines did specialized analog calculations in the early 20th century where
introduced. The first digital electronic calculating machines were developed
during World War II. The first semiconductor transistors in the late 1940s were
followed by the silicon-based MOSFET (MOS transistor) and monolithic integrated
circuit (IC) chip technologies in the late 1950s, leading to the microprocessor
and the microcomputer revolution in the 1970s. The speed, power and versatility
of computers have been increasing dramatically ever since then, with transistor
counts increasing at a rapid pace (as predicted by Moore's law), leading to the
Digital Revolution during the late 20th to early 21st centuries (Wikipedia
contributors, 2021).
Computer
systems have become an essential part of life, having significant impact on
modern society. A computer system consists of hardware components that have
been carefully chosen so that they work well together and software components
or programs that run on the computer (TechTarget, 2018). It is a set of
integrated devices that are designed to receive, process, manage and present
information in a meaningful format (PEDA, 2021). A computer may be analog,
digital, or hybrid, although most today are digital. Digital computers express
variables as numbers, usually in the binary system. They are used for general
purposes, whereas analog computers are built for specific tasks, typically
scientific or technical. The core of any computer is its central processing
unit (CPU), commonly called a processor or a chip; it consists of an
arithmetic-logic unit to carry out calculations, main memory to store data
temporarily for processing, and a control unit to control the transfer between
memory, input and output sources, and the arithmetic-logic unit (Encyclopedia
of Business, 2021).
The
distinction between a computer and a computer system is largely academic, since
the terms are used interchangeably (Encyclopedia of Business, 2021). A complete
computer including the hardware, the operating system (main software), and
peripheral equipment required and used for full operation can be referred to as
a computer system. This term may as well be used for a group of computers that
are connected and work together, in particular a computer network or computer
cluster.
1.2 Statement
of Problem
Computer
system is a basic, complete and functional hardware and software setup with
everything needed to implement computing performance; although its assemblying and
disassembling seems like a difficult job, once an individual get used to it, it will be realize that it is easier to be done.
Assembling a computer system means connecting different components of a
computer so that users can use the computer.
Thus this research work will therefore focus on the assembling and disassembling
of a computer system from the point of unplugging a computer to the point of rebuilding
it effortlessly.
1.3 Aim
and Objectives
The
aim of this research work is to disassemble a computer system and assemble all
the various components back into a computer system.
Other
objective of the study is to:
- Identify
all the various components of a computer system
·
Examine the importance of each
components in the computer system
·
Carryout the assembling and dissembling
of a computer system.
1.4 Significance
of Project
The
study will provide useful information for the review of related literature on
the various components of a computer system and how they can be assembled to
form a computer system. Findings of the study will enlighten upcoming computer
scientist about the computer system.
1.5 Scope
of Project
This study will only focus on the computer system
and its hard ware components alone. The hardware components include the CPU,
Monitor, Mouse, and Keyboard which will be use to computer if the system is
proper assembled.
1.6 Limitations
of Project
Some limitations that the
researcher faced are: time limitation and cost. Another limitation is that the
researcher is not well conversant with the steps in carrying out a research
work. This being the researcher’s first attempt at a study of this nature.
