Working as a Computer Technician

A computer technician’s work will involve: 

  • Problem solving
  • Solving Hardware Crashes
  • Troubleshoot computer problems
  • Train users on new technology

As computer hardware and software become more sophisticated and continue to change at a fast pace, support specialists will be needed to educate and update users. Graduates with strong computer and communications skills combined with practical work experience will do best in the job market.

Opportunities
Computer technicians will always be in high demand because computers are used everywhere now and since they are machines they will have problems and that is where a well qualified Technician will be needed.

Some job opportunities include:
• IT Technician,
• Help Desk Support,
• IT Support Officer

Technical Assistants or Junior technicians without qualifications may earn well below average wages; but skilled, experienced and qualified technicians in developed countries may be in the top 10% of wage earners.

Risks and challenges
Technology changes quickly so you will need to remain up to date with any industry changes.

You may be required to deal with highly stressed situations at times, when people are struggling, or upset if they are at risk of losing large amounts of date etc.

How to become a Computer Technician
To get a start you need basic skills and experience. A course such as a vocational computer servicing course is an excellent starting point and may be all that is needed for you to secure some casual work in a computer shop. Obviously the more you study, the better your skills and opportunities. If you have the time; undertake Computer Servicing I, II, III and Computer Networking with us.

Over time, and with further study, your skills can develop, and opportunities expand.

As with anything technical, hands on experience is essential for becoming a good IT technician.
