The role of a network designer cannot be underestimated. After all, computer networks are vital parts of virtually every business or organization. Computer and network system administrators are responsible for these networks and their daily operation. They organize computer systems, as well as installing and supporting them. These systems could be intranets, network segments, wide area networks (WANs), and local area networks (LANs), as well as other data communication systems.

Telecommunications networks are critical in any type of telecommunications system. For performance to be up to scratch, the network will need to meet a number of different criteria. This is why there are a lot of different components that must be considered when ensuring the network is optimally designed, and there are typically a number of hurdles to overcome along the way. This is even more so the case when you consider the fact that networks have become increasingly complicated and new technologies are being developed all of the time. Telecoms businesses cannot afford to deliver poor performance or fall behind, which is why network designers are so vital.
