This paper was created with the aim of increasing our knowledge and to fulfill the assignment of the Information Technology Systems course group. Basically, a computer network can be likened to a wired network, namely the connection of cables to one another in a computer system. Two types of cable that are widely used are twisted pair and coaxial. Twisted pair cable itself consists of 2 types, namely UTP (short for Unshielded Twisted Pair) and STP (short for Shielded Twisted Pair) while coaxial cable also consists of 2 types, namely coaxial think and coaxial sthink. UTP cable is the most common type of cable that is often used in local area networks (LANs) as a medium for connecting computers and network equipment (hubs or switches), because the price is quite affordable, flexible and the performance shown is relatively good. a computer network using cables, there are two types of cables that are often used, namely straight-through cables and crossover cables. As for making UTP Cross and Straight cables, you must have the following tools: To connect a computer network using cables, there are two types of cables that are often used, namely straight-through cables and crossover cables. As for making UTP Cross and Straight cables, you must have the following tools: Tank Crimping, UTP cable, RJ-45 connector, and Lan Tester. This paper will discuss how to cut and connect the UTP cable.
