What is the most common cable used today?
- A.
Coaxial
- B.
UTP
- C.
STP
- D.
Fiber
- E.
Antenna
Correct Answer
B. UTPExplanation
UTP (Unshielded Twisted Pair) is the most common cable used today. It is widely used for Ethernet connections in homes and offices. UTP cables consist of four pairs of twisted copper wires, which helps to reduce electrical interference and crosstalk. It is cost-effective, easy to install, and provides good performance for most networking needs. Coaxial cables are commonly used for cable television and internet connections, but UTP has become more popular due to its higher data transfer rates. STP (Shielded Twisted Pair) and Fiber cables are used for specific applications that require higher bandwidth or greater resistance to interference. Antenna is not a type of cable, but a device used for wireless communication.Rate this question:
