They should
Not be fully relied on
Q.1 Assuming you are head of IT in your organization, Write down the guidelines for
preventive maintenance and repair of organization IT equipments and accessories in
details which service providers have to adhere to when carrying out the exercise. (Note
that your guideline should stipulate how often preventive maintenance should be carried
out, parts to be maintained and exactly what should be done on each part during
preventive maintenance and the report format which service providers should document
to you as head of IT department).
Disassemble CPU, mouse, keyboard and monitors then blow dust particles
Surface cleaning of hardware using volatile solvents or liquids
Check the battery life
Use CD or DVD drive cleaners
Software revamping
Check the running status of application software
Q.2 Explain clearly the meaning of the following terms in as far as Pc repair is
concerned:
(a) Jumper Pin
This is a small metal connector that acts as an on/off switch and is used to alter hardware
configurations
Jumpers are used in setting the operating mode for ATA drives on (master, slave or cable
select)
(b) Cmos Battery
CMOS is an acronym for Complementary Metal Oxide Semiconductor.
Is the term usually used to describe the small amount of memory on a computer motherboard
that stores the BIOS settings?

2. The function of the CMOS battery is to maintain important information for the BIOS to begin the
start up sequence in computers. It stores the date and time and the system configuration
details
(c) DDR3 RAM
DDR3 SDRAM, an abbreviation for double data rate type three synchronous dynamic random
access memory, is a modern type of dynamic random access memory (DRAM) with a high
bandwidth ("double data rate") interface.
(d) PCI card
Conventional PCI, often shortened to just PCI, is a local computer bus for attaching hardware
devices in a computer. The PCI bus supports the functions found on a processor bus, but in a
standardized format that is independent of any particular processor
(e) IDE interface
Abbreviation of Integrated Drive Electronics. An IDE interface is an interface for mass storage
devices, in which the controller is integrated into the disk or CD-ROM drive.
Q.3 Assuming you are provided with two IDE hard disks and two IDE CD drive,
explain clearly how to configure them in one CPU having onboard IDE
interface, stating clearly the positions of jumper pins for each of the devices
under configuration.
With the help of the IDE interface I will first connect my hard disk on board as a primary master
with
Jumper pin placed at master on the hard disk I will then connect the power cable from the
power supply
Again I will use mi second IDE interface and I connect my second hard disk on a primary slave
without a jumper pin on it the I connect the power cable from the power supply
I will then bring my IDE CD drive with the help of an IDE interface I will place it on secondary
master on board but with a jumper pin on it placed at the master

3. Then I will get my second IDE CD drive with help of an IDE interface to connect on a secondary
slave interface on board without a jumper pin on it
