The main purpose is to reduce cross-talk between the cable pairs. It also has the happy side effect of keeping the cable pairs neatly together while making connections..

UTP or unshielded twisted pair
1. Copper UTP (Unshielded Twisted Pair) 2. Optical Fiber
Actually, a UTP cable doesn`t have any shielding. UTP stands for Unshielded Twisted Pair.
UTP stands for Unshielded Twisted Pair. This is a type of cable which has the shielding above the twisted cables for EMI/EMC protection.
The UTP (Unshielded twisted pair) cable is preferred; it's far less expensive to install in large amounts.

Coaxial cable, STP cable, UTP cable
CAT 5 Cable and RJ 45 Cable (Twisted-pair Ethernet). Unshielded twisted-pair (UTP) cable
A UTP cable has 4 pairs of twisted wires. In a coaxial cable, there are two conductors, one inside the other. Since they have a common center, or axis, they are called "coaxial" (co-axial).A UTP cable has 4 pairs of twisted wires. In a coaxial cable, there are two conductors, one inside the other.

UTP (unshielded twisted pair) Cat5 or Cat6.
Unshielded Twisted Pair (UTP) cable is a type of networking cable commonly used in Local Area Networks (LANs) for data transmission. It consists of pairs of insulated copper wires twisted together to reduce electromagnetic interference and crosstalk. UTP cables are categorized based on their performance, with Cat5e, Cat6, and Cat6a being popular choices for supporting high-speed internet and network connections. Their simplicity and cost-effectiveness make them a standard choice for wired networking in homes and businesses.
Mainly in LAN we can use 4 types of cables: 1) STP - Shielded Twisted Pair 2) UTP- Unshielded Twisted Pair UTP have 2 types 1 is Straight Cable 2 is Cross Cable 3) Coaxial Cable 4) Fiber Optic Cable
