Wired networks
Fredrik Nilsson · 2023
Networks provide data exchange between servers and nodes in a computer system. In the early days of office and enterprise networking, many different technologies emerged, such as Token Ring, Banyan VINES, Ethernet, and Fiber Distributed Data Interface. The Ethernet standard is available in many versions, depending on the transfer medium used and the achievable data rate. This chapter briefly describes the most important versions in terms of network video. In wired networks, all nodes must be connected through some type of network cable. Many different types are available, including twisted-pair or fiber cable, and each type is available in many different versions. The primary difference between the different categories explained earlier lies in whether the cable is shielded and, if so, which type of shielding it uses. Power over Ethernet provides the option of supplying devices with power and Ethernet through their network cable.
