Pliers are a hand tool that is used in fixing a computer system. It is a kind of tool that serves as many purposes which include; bending, holding, a little bit of screwing and pulling as well. It is enabled by the grip of the user; its work output depends on the kind of force which the user exacts on it. It always has an iron mouth with two grips which are mostly rubbers. There are different types of pliers and they all serve for different purposes; there are some for cutting and there are some for adjusting such as holding and screwing. Just like the screw driver, there are automated pliers and there are manual ones but the most common type of pliers around is the manual ones. I used the manual pliers to remove some components of the motherboard.

2 Software Tools

Just like there are many types of tools which are used to fix hardware problems, there are also different types of software tools that can be used to fix software problems and this includes disc defragmenter and disc cleanup.

Disc Defragmenter

Disk Defragmenter is a computer program included in Microsoft Windows designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique commonly known as defragmenting.

The purpose is to optimize the time it takes to read and write files to/from the disk by minimizing head travel time and maximizing the transfer rate. In windows XP, disc defragmenter is also used to improve system start up times. I realized that the files on the computer system are scantily arranged which makes its speed slow so I decided to carry this out to allow a high speed.

Disc Clean-Up

Cleanup tool is an application on the computer that helps it to safely get free space to save and run the certain basis routine of the computer. Clean up tool can help the computer to get rid of some files that are useless or irrelevant to the computer system. This tool is used to delete temporary files, windows temporary files and some optional windows component that are not in use. It also gives the option and help of removing some personally installed programs that are no more in use. This was very useful because it is going to help the computer to run freely without any obstruction or barrier. Making free space available to the computer also helps to from incessant freezing.

M1. 1ST Hardware Problem

The first hardware I encountered while doing the practical was that the IDE cable that connects the hard disk to the motherboard was not there. Without this connector, the hard disk can not be recognised by the computer because there is basically no connection. Even if there is one but it is not connected the right way, the hard disk would not function as well.

Options

The IDE cable should be fitted

The hard disk would not work if it is not connected to the motherboard therefore there is no other option than to install a new one.

Tool/Solution

Seeing that the connector was not there at all, I went to get an IDE cable to enhance the connection. To connect this, I used the principle which goes; the red line on the cable must always be next to the power unit of the hard drive. With that principle, I was able to connect my hard drive to the motherboard easily and successfully.

2nd Hardware Problem

The second hardware problem that I found was that the mouse not working; the icon was not showing on the screen. Without the mouse, most operations that should be carried out on the computer could not be done. Clicking and navigating was basically absent from the features of the computer system therefore something had to be done to it.

Option(s)

Fix the mouse by opening it with a screw driver and check if the problem can be fixed.

Get a new mouse

.

Tool/Solution

The first thing I checked was the cable that connects the mouse to the computer to see if it was connected at all or not and to see if it was connected the right way. I saw that it was rightly connected so I decided to change the mouse because it was obvious that the present one is broken. I got a replacement mouse and then connected it to the computer then it worked.

M2. 1st Software Problem

The first software problem that I detected on the computer system was that there was no service pack installed on it which made the computer totally unsecured and useless. Service pack specifically contains all about security because it provides protection against viruses, hackers, worms and it includes firewall, pop up blocker for internet explorer and the new windows security centre. Service pack also supports the user with modern features and some default safeguarding measures that will increase the overall security levels of the computer.

Option(s)

Install a fresh service pack on the computer

The overall safety of the computer is at risk if there is no service packs on it therefore there is no other option to install a new service pack.

Tool/Solution

The solution that I used to solve this problem is obviously to install a service park on the computer. This is done on a CD ROM and is installed by inserting the CD and running it. During this process, the application asked series of question to enable the right installation. When this was successfully installed, the computer is ready to use.

2nd Software Problem

The second software problem that I discovered was that there was no antivirus software installed on the system which could make it prone to attacks. Antivirus is designed to tackle every sort of attack on the computer. It helps to prevent, detect and treat any form of virus or Trojan that tends to affect the operation of the system. Without virus protection software, the data stored on the computer could be at risk of being lost, corrupt and being accessed by a stranger.

Option(s)

I can turn on the firewall which is a computer feature that works like antivirus but it is different from antivirus because it has its own area of specialization. It specializes in blocking all attacks and unauthorised communication within an internet connection.

I can also install new antivirus software on the computer to make it safer to manipulate and use.

Tool/solution

The solution to this problem was to buy new antivirus software and install it on the computer system. This is to make the computer safer to use. During the installation, the software requests for some permission from the user and also asks some questions like language and storage file option.

M3. Hardware and Software Tools

Screw driver

Screw driver is a kind of tool used for dissembling items i.e. the loosening of screws for removal. It can also be used to assemble items by tightening them. A screw driver consists of a wooding or plastic head with either a star-like or flat tip. Its use depends on the type of screw that the user wants to loosen or tighten i.e. star screw or a flat screw. Like most other tools, there are two types of screwdriver and they are the automated one and the manual one. The automated one can be used with a rechargeable battery or a disposable battery while the manual one only requires man power. I used the screw driver to open up the computer panel so as to be able access the hard disk drive and the mother board to fit a new IDE cable.

Pliers

Pliers are a hand tool that is used in fixing a computer system. It is a kind of tool that serves as many purposes which include; bending, holding, a little bit of screwing and pulling as well. It is enabled by the grip of the user; its work output depends on the kind of force which the user exacts on it. It always has an iron mouth with two grips which are mostly rubbers. There are different types of pliers and they all serve for different purposes; there are some for cutting and there are some for adjusting such as holding and screwing. Just like the screw driver, there are automated pliers and there are manual ones but the most common type of pliers around is the manual ones. I used the manual pliers to remove some components of the motherboard.

Suitability of each

Scenario: I want to loosen a computer component to fix a problem with the mother board and I want to tighten it back.

Choosing the suitable tool out of pliers and screw drivers.

A screw driver should be used in this case although both of them can both be used to tighten and loosen things. However, pliers can not be used to effectively tighten or loosen things; they are not the perfect tool. They can only be used in emergency cases or when the user is stranded with just one tool. A screw has a star-like or flat-like type of head and it can be effectively removed or tightened by a screw only. This should be done to avoid any fall out after the components has been assembled again.

Software tools

Disc Defragmenter

Disk Defragmenter is a computer program included in Microsoft Windows designed to increase access speed by rearranging files stored on a disk to occupy contiguous storage locations, a technique commonly known as defragmenting.

The purpose is to optimize the time it takes to read and write files to/from the disk by minimizing head travel time and maximizing the transfer rate.

This was very useful because it is going to help the computer to run freely without any obstruction or barrier. Making free space available to the computer also helps to from incessant

Suitability of each

Scenario: my computer is so slow that I can hardly get things done on it because it keeps freezing whenever I try to work on it.

Choosing the suitable tool out of Disc Clean-Up and Disc Defragmenter

Disc clean up is used to organise and clear up files that are not in use and are using maximum space which could be used by other files to make the computer work smoothly. Disc defragmenter is an application which can be used to arrange files and increase access speed of the computer. In this case, the suitable software to use is the disc cleanup tool because it clears up space and organise the files as well.
