Recommendations For change:

I have not done an absolutely new system as it would be costly and worthless. Most of the computers have good enough specs to run the software it needs to. Although here are some highly recommended changes.

Optical Mice:

This would greatly help as the ball mouse's we have now get clogged up with dust and are need to be cleaned. Students cannot clean the mice themselves as they are locked so students don't steal the balls. If optical mice were bought for the computers they would never need to be serviced and would brake rarely.


DVD ROMS Would be great for the school as they are a big storage medium so students will be able to hold all their Assignments on just one disk. Also educational video DVD's could be watched all around the school.

Wireless LAN:

Wireless LAN would be a great bound into the future as computers could be moved anywhere in school grounds without the hassle of network cables. Also students could bring in laptops and be able to log in to access their H: drive and Internet.

Detailing the proposed system:


Network vs. Stand Alone


' Advantages

' People can access their files from any computer in the network

' People can share their files easily

' Internet Sharing


' Virus's can spread through network

' Costly to set up

' Timely to set up

Stand Alones System:


' Cheap to setup

' Viruses cannot spread

' Fewer problems.


' Have to use same computers to access work.

' Have to have modem for each computer and multiple phone lines.

' Expensive for Internet.

' Slower internet.

' Cant send files to others.

Definitely A network is a must. We already have network slots positioned all around the school and there would be no point in not using them because there advantages are multiple. The advantages of having a network speak for themselves. Possibly in the future we could upgrade the network to a wireless one!

Input Devices:

Ball MouseThe ball mouse is commonly used in modern society. They are very cheap and easy to find. They can either have a cord or be cordless. They do need to be cleaned occasionally.

TrackballTrackballs are commonly used on laptops built onto the keyboard because they do not take to much space and don't need a flat surface to be used on. They are not used much for PCs.

Optical MouseOptical mouse have come of popularity in recent years. Now with most new computers an optical mouse will be included. They are not very expensive and are low maintenance.

Graphic TabletTablets are Mostly used in PDFs which are a very modern small computer which fits in your palm. With tablets you use a special pen to select things and also to write. This type of device is costly.

As said before, I think the optical mouse would be the most appropriate device because it is cheap and low maintenance.

Output Devices:

Dot MatrixA dot matrix is an old kind of printer. It prints in only black and white and the quality is not all that good. Finding the printer and the cartridges would be very hard.

Bubble JetPrinter commonly used these days. These printers print in both black and white and ...
