Detailed explanation-1: -It is the least expensive medium of transmission for short distances. It is relatively easy to implement and terminate. It can be used to carry both pf the data analog and digital data. I turn are less likely to cause interference themselves.
Detailed explanation-2: -The UTP cable is the most common twisted-pair cable used in Ethernet networks. It also is used for traditional telephone (UTP-Cat1) systems. UTP cables are popular all over the world due to their low cost, ease of installation and flexibility.
Detailed explanation-3: -Twisted pair cables are thinner and less expensive. Coaxial cables are better shielded from crosstalk. Twisted pair cables provide high transmission rates.
Detailed explanation-4: -Twisted Pair Cable The twisted wires have interference cancelling properties. Thus, it is suitable for data and voice infrastructures over short distances as the cable reduces the effect of electromagnetic interference on electronic signals.
