IT Networking

Networking is a specific branch of information technology (IT), and is one of the fastest-growing areas of IT.

It involves the processes of building, using and maintaining computer networks – including hardware, software and protocols – so that multiple computing devices can share data.

An IT network engineer designs the computer networks that organizations rely on to access, share, and store information.

Network engineers implement and maintain local area networks (LAN), wide area networks (WAN), the corporate intranet and Internet connections, and the virtual private network (VPN).

The complexity of the work depends on the organization: a small start up may employ a computer engineer to oversee a handful of desktop computers, while an engineer at a large multinational manages a web of complex, globally distributed networks.
