Select the statement that is false. UTP cable is unshielded. Twisting two pairs of wires results in both wire being less affected by external noise. Cat 5 cable is composed of four shielded twisted pairs of insulated wires. O Increasing the number of twists per meter in the Cat 3 cable reduces crosstalk.

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
