 The absence of the devices that can connect wireless
 A connection drop at the random times in the circuit
 The network of WI-fi that disappears entirely
 Te crashing of the router that can only be connected by restarting
QUESTION TWO
Car maintenance presentation
The importance of car maintenance
 It improves the much-needed safety
 It enhances the reliability and the performance of the car

 Car maintenance will save the operator the repair cost
 It will give the car a higher resale value
 Car maintenance helps in keeping the environment clean.
 The car maintenance helps in the minimisation of the roadside emergencies.
How to achieve the car maintenance
1. Inspect the vehicle regularly. The owner’s manual will give details on how to do this.
2. Learn the to interpret the meaning of the warning lights on the indicators.\Some of the
lights to give attention may include the engine light, the service engine light, the
electrical fault light, the brake warning light, the coolant warning light and the oil
warning light
3. Check the tyres for the wheels and the tire pressure. It is usually affecting the comfort
of handling the car
4. Check the tread depth for the car tire and ensure they are in proper conditions to avoid
sliding of the car.

Question 4
An interview with the designated authority on how to maintain the computers
Computers are just consumable products that also fail due to the hardware or software
complications. Whenever the computers fail to function as expected, they are taken to the
shops for them to be repaired. I had the opportunity to interview OWILI, a company that
repairs the computers located in kiambiyo Nairobi. Some of the most common computer
repairs questions were sufficiently answered.
STUDENT: What are those common problems that are associated with the computer that you
solve in shop workshop?
OWILI: The problems are quite a number. For effective understanding, the problems can be
broken down in the following sub heading
1 the malware removal-It is the most common with the computers. It is almost unavoidable
problem that seem to be attached to nearly everything. The simple’s things that are taken to

get recognised institution can fail to execute command as given and give something else.
Keep the tool bar as minimum as possible. Only the ones that one cannot survive without
should be left. The more the number of the toolbars to be opens the slower the browser
Houser, M.L., Fleuriet, C. and Estrada, D., 2012. It will help to organise the security details
while at the same time making perfect decisions with the left clicking button. A void using
the free screen savers the flashy ads together with the free music downloads that are not
obtained from a very well recognised internet browser. Also avoid the programmes and
websites that usually fix automatically to the browser.
2 Bad Hard Drives on the Laptops: The major problem is because people normally close the
lids and put their laptops inside the bag and just start moving around with them. When the
hard drive is on, the computer should not be moved with a lot. It should be shut by following
all the procedure properly or it should be put in a hibernation mode and it be waited to go off
completely. Being that it is a laptop, one should always be cautious and avoid being too
rough.
3 Overheating the component-This can be controlled when one applies preventive
maintenance. The laptop should be checked at least after every 2 years for the condition of
the motherboards and even fans.
STUDENTS: What are the tools you always prefer using or the programs that you always use
to fix or diagnose the computer?
OWILI: It is not all about my preference, but it is about what is appropriate to solve the
problem at hand. One needs good tools to do a better job. To be able to properly diagnose a
computer, one must be able to know what is not working correctly within the system and
what is working. The hardware and the software are diagnosed together although the software
may always take one a few minutes to establish what the problem is. For the starters, one may

need to keep on the top service packs, virus definitions and the updates. Here one will purely
use observation for the success. The user therefore must bring the computer for check-up
regularly.
STUDENT: Which is the worst computer brand have ever worked with?
OWILI: I would not wish to single any of them out now. Considering the ease and quality of
the installation, the companies are competing favourably. Most of their desktops tend to be
propriety. The best computer to buy is one whose spare parts can be found in the local shops.
STUDENTS: Would you recommend Dell computers to any of your clients?
OWILI: I will not recommend the Dell computers to most of my clients. It is only you that I
would recommend the Dell for but in a condition that you will be using it specifically for the
multimedia purposes to do the video editing.
Do you recommend a specific backup method to your clients? The backup solutions may be
different both on the hardware and the software. The external drives and online services
should be used by those operating from home.
How much is the average labour cost for repairing the computers?
OWILI: It is difficult to tell on this because it varies from shop to shop. In some shops they
provide diagnostic services while I the others it is done at a fee.
STUDENT: Should laptops be repaired or just replaced in relation to the cost?
OWILI: This will depend on the age of the computer and the level of damage to be repaired.
If the level of damage is too high then it better be replaced.
STUDENT: What is your priority tip for the computer users?

OWILI: Never skip the computer maintenance. There is an automatic cost attached to owning
a computer.
A report on the interview
The interview was conducted on 23rd May at the Jumbo workshop for the computers. The
findings from the interview were very elaborative and the benefits of computer maintenance
were emphasised on
Computer replacement verses repair were compared against the cost and the informed
decisions made.

Types of the written communication
Communications are of two types that is oral and written communications. The written
communications involve that communication in the form of written words. The most
common forms of this communication may include the following; memos, emails, reports and
the instant messages and this are commonly used internally by the business. Wieland, L.S., et
al
T he clients that are considered to be from the outside business are normally addressed
through the use of letters, emails, proposals internet websites, faxes, contracts, brochures,
news releases and telegrams.
The advantages of the written communications may include the following;
It saves on the expenses for example one can send an e mail instead of calling long distances
Whenever there is a dispute, this form of communication provides a written proof
It does not need the personal contact.
This form of communication has a number of disadvantages that include the delay in
communication, lack of secrecy and costly if the recipient and the sender are close to each
other that will still demand for the pen and book. A., LOGMEIN Inc, 2012.
The written information should be done in codes that are only known to the recipients and the
sender so as to enhance the security and secrecy.
QUESTION 7
