At its simplest level, networking is a way of transporting and exchanging data between workstations – or nodes – over a shared medium within an internal IT system. A good network solution entails the design and construction of a network, as well as the management, maintenance and operation of the infrastructure on an ongoing basis.
Networking architecture links devices and endpoints together through a local area network (LAN) or to a larger network, such as the internet or wide area network. The key characteristic of the economy today is the sharing of information. Some information can be shared freely and other data needs discretionary access, which comes with a variety of security measures to limit access.
