Network Engineering involves designing and maintaining both software and hardware necessary for computer networking. Network engineers are highly trained technicians and analysts specializing in local networks (LANs) and wide area computer networks (WAN). With the evolution of the Internet, Network Engineering involves coming up with programs, devices, peripherals and all elements necessary for computers to communicate. Network engineers are responsible for implementing, maintaining, supporting, developing and, in some cases, designing communication networks within an organization or between organizations. Their goal is to ensure the integrity of high availability network infrastructure to provide maximum performance for their users. Users may be staff, clients, customers and suppliers.
Networks can include: 1) Computer; 2) Voice; 3) Firewall. Network engineers may work internally as part of an organization’s IT support team, or externally as part of an outsourced IT networking consultancy firm working with a number of clients.
Other job titles used to refer to this kind of work include:
1) Network/helpdesk support
2) Support/security/systems engineer
3) IT/systems support engineer
