Computer Servicing II VIT204

 INTERMEDIATE COMPUTER SERVICING - DISTANCE LEARNING COURSE

The urge to upgrade, repair or just tinker with the insides of a computer system can be quite strong in some people. Initially the task might seem daunting, however with experience and a little guidance most repairs can be undertaken, hardware components installed or adjusted for optimal performance.

For the first timer, the process can seem to be fraught with danger, and in terms of doing more damage than good it can be. If you follow a few basic steps though you should be able to work quite safely, both from your own and the computers point of view.

This course takes the skills that have been learnt in Computer Servicing I and builds on them to develop an enhanced level of understanding and capabilities.

Pre-requisites: Computer Servicing I (or equivalent).
