Unshielded Twisted Pair
A twisted pair cable without an internal shield is called a UTP cable or an unshielded twisted pair cable. The outer insulating jacket shields the cable from physical stress and damage, but not from electromagnetic interference (EMI). Due to its low cost, flexibility, and high performance, unshielded twisted pairing (UTP) cable is the most common network cable in workgroup and departmental local area networks (LANs).
Compare Physical Interface and Cabling Types
Cables (coaxial, twisted pair, fiber optic, and telephone lines) are made up of various network hardware components, network adapters used in computers connected to networks (hosts), and concentrators or bridges used in networks. connect to physical networks where physical networks come in various sizes and hardware configurations. Local area networks (LAN) and wide area networks are the two most common types of networks (WAN). A local area network (LAN) is a network in which communications are restricted to a modest geographic area. A single office building, warehouse, or university, 1 to 10 kilometers (1 to 6 miles) in size.WAN is a network that enables data connections across geographical regions that are bigger than those covered by LAN, such as spanning an entire continent. There is also a middle class of networks known as metropolitan area networks (MANs). MANs are bundled with WANs in this guide and are not frequently distinguished. Standard Ethernet, IEEE 802.3 Ethernet, or token-ring hardware are frequently used in LANs for the physical network, while common carrier networks are used in WANs and asynchronous networks. In both situations, the operation of the physical network is typically governed by networking standards from organizations like the International Telecommunication Union (ITU) or the Electronics Industry Association (EIA) (ITU).
