Networking must go beyond the systems development life cycle to the full system life cycle over the network’s life.
It also needs to understand the business system in which each network component operates.
In information technology, networking is the construction, design, and use of a network, including the physical (cabling, hub, bridge, switch, router, and so forth), the selection and use of telecommunication protocol and computer software for using and managing the network, and the establishment of operation policies and procedures related to the network.
When looking at networking basics, understanding how a network operates is the first step to understanding routing, switching, and wireless. The network operates by connecting computers and peripherals using switches, routers, and access points. These devices are the essential networking basics that allow the various pieces of equipment connected to your network to communicate with one another, as well as with other networks.
