Computer Technician

Computer technicians or computer service technicians are workers who install, diagnose problems, repair, maintain and upgrade a wide variety of computer and peripheral equipment.

Being a computer technician involves having the knowledge on how to build a PC from scratch, develop problem-solving techniques, run tests and diagnostics, technical support and installations.

There are basically two types of technicians:
In-house Technicians, work for a particular company, repairing and maintaining the computers and the network for the company.

Contract Technicians, work for different companies on a contractual basis and check all their hardware or technical requirements; they may set-up and repair PCs and give technical support.
Tasks of computer technicians are complex and demanding. Technicians are responsible for the effective functioning of a wide range of computer equipment that can vary from personal computers (PCs), tele-processing and network equipment, small systems, to large and complex mainframe systems.

They are responsible for carrying out high quality repair and maintenance on the equipment for which they are responsible. They need a thorough knowledge of both theoretical and practical electronics and how to effectively use all the diagnostic tools and techniques available to minimise disruption to the customer and to improve productivity. Computer technicians also need the necessary software skills required for the type of equipment that they maintain, i.e. DOS, Windows, Unix, Novell, etc.

The work requires that computer technicians must keep abreast of the latest technological developments. Even after qualification, they must regularly attend training courses to update their knowledge and skills. Since technology is always changing and improving, technicians’ training will continue throughout their career.

Technicians are responsible for keeping customers satisfied. They must understand and be responsive to customers’ needs and requirements. They need to communicate effectively with customers regarding the repairs done and keep them fully informed of any unresolved or outstanding problems. They also attend customer performance-monitoring meetings and develop solutions for existing problems. They would be well advised to adhere strictly to any commitments they have made, especially to customers.

Technicians work indoors in computer rooms and departments of customers. They often need to travel between jobs or customers, although distances are usually short.
