The concept of planned maintenance reduces the requirement of deal with unforeseen breakdown and to minimize the needs for repair. In addition , it enables repair to be carried out in an organized manner at a convenient time without emergency.

1. SIWES TECHNICAL REPORT
BY
SHIMAPEVER ANGELA UMM/SAE/998
SUBMITTED TO THE DEPARTMENT OF
MATHEMATICS AND COMPUTER SCIENCE,
UNIVERSITY OF MKAR,MKAR
IN PARTIAL FULFILMENT OF THE
REQUIREMENT FOR THE AWARD OF B.SC.
COMPUTER SCIENCE

2. KNOWLEDGE ACQUIRED
COMPUTER MAINTENANCE AND TROUBLESHOOTING
Computer maintenance
• Maintenance is defined as the practice of keeping computer in a good
state of repair planned or unplanned.
Planned maintenance
• This is the necessary work organized and carried out with fore thought ,
control and records to keep or restore facility to an acceptable standard.
• The concept of planned maintenance reduces the requirement of deal
with unforeseen breakdown and to minimize the needs for repair. In
addition , it enables repair to be carried out in an organized manner at a
convenient time without emergency.
Unplanned maintenance
• This is the work carried out without keeping records without control

3. Maintenance strategy
This are the methods used in maintaining the requirement. The
strategies are in three categories :
• Preventive maintenance : this is performed even if the computer is
still operating in its efficient level. It is done to prevent degradation
of performance
• Corrective / breakdown maintenance : this type of maintenance is
required when a system or sub-system finally collapsed.
• Routine maintenance : this involved a regular scheduled or time
table strictly adhered to by the owner of the computer and the party
offering the maintenance service to perform an overhaul of
machinery.

4. Troubleshooting
HARDWARE COMPONENTS OF A COMPUTER SYSTEM.
• RAM: RAM is an abbreviation for Random Access Memory. It is a
short term memory that is used to store document 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
• Hard drive: This is the device used for long time storage of
information. The main storages for a computer are the internal hard
drive (also called a hard disk).

5. Motherboard: This is a large electronic board that is used to connect the power supply to various/other electronic parts and
to hold these parts in place of the computer. 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
operation of the computer such as linking hardware and the software. Motherboards also contain small battery like a watch
battery and the chips that work it to store the system time and other computer settings.
System Unit Case: This is also called a tower or housing. It is the box that encloses many of the computer system
components.

6. NETWORKING CABLES
The Ethernet cable are network cables containing eight wires with different colours. These wires are arranged
and terminated according to the type of connection needed.
We have the straight through terminated cable, for connecting devices that are dissimilar (e.g. computer to
hub/switch, switch to hub etc.)
We also have the cross over cable, for connecting devices that are the same (e.g. computer to computer, switch to
switch, hub to hub etc.)
The colors of the wire are green, orange, blue and brown. Four of these colors in full while the remaining four have
the colours but with the stripes of white along it.
For straight through cables, the color code is:
White/Orange (i.e. orange color striped with white) followed by full orange, white/green-blue, white/blue-green,
white/brown-brown.
For cross over cables, the color code is:
White/green-green, white/orange-blue, white/blue-orange, white/brown-brown.
All these wires are arranged in line and inserted into the RJ-45 connector which is then held in place (crimped) by a
crimping device

7. We need the following equipment to make a patch cable
RJ-45
LAN cable tester
Crimping tool
Patch panel
Ethernet cable

8. OTHER ACTIVITIES DURING THE TRAINING
Other activities I carried out during the course of my training includes
i. I learnt how to update the drivers of a computer.
ii. I learnt how to install a printer by using the driver software.
iii. I learnt how to back up a system.
iv. I learnt how to upgrade the operating system of the computer.
v. I learnt how to activate the windows operating system using the activator software.
vi. I learnt how to work as a team with my fellow interns.
vii. I was made a group leader to carry out an assignment and I was able to assign different tasks to my group members.

9. TECHNICAL SKILLS ACQUIRED
Below is the list of skills I acquired during my industrial training
i. Knowledge of computer maintenance.
ii. Knowledge in computer hardware and assembling of different parts.
iii. Knowledge in network cabling.
SOCIALAND FUNCTIONAL SKILLS ACQUIRED
i. Ability to work with team, identify and solve problems relating to computer maintenance.
ii. Enhanced communication skills.
iii. Decision making, critical thinking, organizing and planning.
iv. Enhanced teaching and effective learning skills.

10. CHALLENGES ENCOUNTERED
• Challenges I was confronted with at the CASS department were mainly centered on poor inter relationship
among the interns. This was however put in check by the intervention of our supervisor through discussions
and meetings.
• There was also a time when the number of interns at the department was low and this resulted to some of us
being overworked. More students were however deployed to the department during my stay.

11. Summary, Conclusion and Recommendations.
Summary:
• During the course of my SIWES training at Raw material research and development council . The practical
that carried out include; computer maintenance and Network cables. The staffs and my SIWES colleagues
also contribute to the success of the activities carried out at the Raw material research and development
council. The role of computer science in the technology sector is of great benefit to the nation at large and
for me the training was interesting and well understood.
Conclusion:
Conclusively, this student industrial work experience program (SIWES) is a training exercise that must not be
neglected because of the scientific knowledge. In fact, I will emphasis that the practical knowledge I gained is
very important.
Recommendation:
• Orientation should be given to the students by their department / SIWES before the training exercise is
carried out.
• Students should be supervised by school supervisor and ITF officials regularly at least twice during the
training program; this will make the students to be punctual and serious during the training exercise.
• Schools should kindly assist the students in getting place where their IT can be done in future.
