Network Administrators install and maintain hardware and software, document diagnosis and resolution of faults, manage user passwords, security and inventory documentation, ensure the efficient performance of servers, printers and personal computers, and attend to other operational tasks. They may also perform tasks such as help desk support and user training.
You usually need a bachelor degree in a related information technology field (such as network systems administration) to work as a Network Administrator. Training may also be available through Vocational Education and Training (VET). There are also a wide range of vendor and industry certifications available that may substitute for formal qualifications and can be highly regarded by employers.
