IT technical support officers monitor and maintain the computer systems and networks of an organisation. They may install and configure computer systems, diagnose hardware and software faults and solve technical and applications problems, either over the phone or in person.
Depending on the size of the organisation, a technical support officer's role may span one or more areas of expertise.
Organisations increasingly rely on computer systems in all areas of their operations and decision-making processes. It's therefore crucial to ensure the correct running and maintenance of the IT systems.
