SUMMARY The Students’ Industrial Work Experience Scheme (SIWES) is a scheme that was set up to enhance and expose students to acquire adequate and relevant skills that would enable them to perform effectively in their future place of work and assignment. It also exposes students to work methods and enrich their experiences in acceptable methods of handling equipment and machinery that may not be available in the education institution. It is also aimed at exposing students to people from all works of life, hence enhancing their communication skills and ability to interact with people after graduation. This report is a summary of the knowledge and experiences gained during my Students Industrial Work Experience Scheme (SIWES), which was done at Enclave Computer Village, Lagos State. Throughout my SIWES period, I worked at the networking and maintenance sections where I was exposed to the basics of the Hypertext mark-up Language (HTML), network topology, installation of software. The training has afforded me the opportunity to be exposed and learn from my colleagues and other individuals within and outside the organization.

CHAPTER ONE 1.0 INTRODUCTION TO SIWES The student industrial work experience scheme (SIWES) is appreciable skill program, which forms part of the approved minimum academic standard in the various degree programs for all the universities. The scheme bridges the gap existing between theory and practice of the engineering and technology, sciences agriculture, medical and other professional education programs in the Nigerian tertiary institution. It is aimed at exposing and equipping students to the real life working experience. The training lasted for six (6) months, which involve the students, universities and the industries. SIWES was established by the federal Government of Nigeria and is jointly coordinated by the Industrial Training Fund (ITF) and National University Commission (NUC). 1.1 AIM AND OBJECTIVES OF SIWES SIWES is aimed at providing skills for students in their various fields. Some of the various objectives why the program put in place are: 1. To provide an avenue for students in institution of higher learning to acquire skill and experiences in their course of study. 2. To prepare students for the industrial work situation they are to meet after graduation. 3. To expose students to work methods and techniques in handling equipment and machinery that may not be available in their institutions. 4. To make the transition from the school to the world of work easier, and enhances students contact for later Job placement. 5. To provide students with an opportunity to apply their knowledge in real work situation thereby bridging the gap between theory and practice.

CHAPTER TWO EXPERIENCE GAINED Under this chapter two, I will be writing on what I gained and with brief explanation on them to at least explain myself out .I gained a lot from the hardware section, maintenance section, and software section, networking section and programming section but I mainly worked in networking department and programming department. 2.0 HARDWARE SECTION (DEPARTMENT) 2.1

HARDWARE

Hardware is the physical equipment needed for a computer to function proper ly. HARDWARE COMPONENTS Hardware comprise the following components: (i) CASE: This is also called a tower or housing, it is the box that encloses many of the parts (components) discussed below. (ii) POWER SUPPLY: This is used to connect all of the parts of the computer to electrical power, as can be seen in figure 2.1 below. You can find it at the back of the computer.

Figure 2.1: Power Supply

16

(iii)

MOTHERBOARD: This is a large electronic board that is used to connect the power supply

to various electronic parts and to hold these parts in place on the computer. Figure 2.2, shows a mother board. The computer memory (RAM) and processor are attached to the motherboard. On the motherboard you also see the BIOS (Basic Input and Output System) chip that is responsible for some fundamental operations of the computer such as linking hardware and the software.

Figure 2.2: Motherboard (v)

DRIVES: These are devices used for long time storage of information. The main storages

for a computer is the internal hard drive (also called a hard disk).A typical hard disk is the one in figure 2.3 below.

Figure 2.3: Hard drive (iv)

CARDS: Cards is used to describe important tools that allow your computer to connect and

communicate with various output devices. The term card is used because these items are relatively flat, with the sound card, video card, a network card and a modem.

17

(v)

RAM: RAM is abbreviation for Random Access Memory. It is a short term memory that is

used to store documents while they are being processed. Also note that the amount of RAM in a computer is one of the factors that affect the speed of a computer. Seeing below is a typical RAM in computer in figure 2.4.

Figure 2.4: RAM (vii) PROCESSOR: Processor is the main ‘brain’ of the computer system, as can be seen in figure 2.5. It performs instructions and calculation that are needed and managed a flow of information through a computer. Processors are continually evolving and becoming faster and more powerful. It is measured in MHz (megahertz) or GHz (gigahertz).

MAINTENANCE

Maintenance is a process of taking necessary precautionary and correcting measures to prevent the computer from breaking down. We also use precautionary maintenance and correcting maintenance in maintaining a hardware. 2.2.1 Precaution maintenance: This has to do with the process of taking necessary preventive measures and putting in place the required resources to prevent a computer from breaking down. There are some common hardware problems that can be avoided or at least made less frequent by taking particular preventive measures with computer which are: Dust control: Dust is very harmful to computer part. Excess dust can cause mechanical

1.

failures, particularly on computer components with moving parts. We minimize dust in a computer lab which is an important part in computer maintenance. Preventive measures of dust effect (i)

Computer should be regularly dusted (wiped with a dry cloth or duster).

(ii)

When a computer is opened for others repairs, the dust that has built up inside the case should be blown out using blower etc.

2.

Heat control: When noticed that computer parts precisely CPU, produce a large amount of heat while operating, it is important that this heat is dissipate so that the computer is not damaged by overheating. Preventive measures of heat effect

(i)

A laptop computer should not be left running for any length of time on a soft surface (like a

sofa) that conforms around it. (ii)

A desktop computer case should not be used while in an enclosed cabinets.

19

(iii)

It is ideal that computer lab temperature should be kept low, using air conditional is also good

option since the windows can be kept close to minimize dust. 3.

Surge protection: At times, electrical supply does not have a uniform (well controlled)

voltage. Voltage is also due to surges that occur; voltage surge can be very damaging to computers and electrical components. Preventi...
