Unshielded Twisted Pair (UTP) is a type of electrical cable commonly used in networking and telecommunications. It consists of pairs of wires twisted together to reduce electromagnetic interference. UTP cables are widely used for connecting computers, phones, and other devices in local area networks (LANs). UTP cables come in various categories, such as Cat 5e and Cat 6, which indicate their performance levels and data transmission speeds. They are popular due to their cost-effectiveness, flexibility, and ease of installation, making them a standard choice for both residential and commercial networking applications.
