Question

Which of the following cable is used for transmitting voice, data and video?

Twisted pair

Coaxial

None of these​

Answer 1

Answer:

Coaxial cables

Explanation:

Coaxial cables are high-frequency transmission cables made up of a single solid-copper core that transfers data electrically over the inner conductor. Coax

has 80X more transmission capacity than twisted pair cables.

Answer 2

lAnswer:

Twisted pair cables are literally a pair of insulated wires that are twisted together. While this does help to reduce outside noise, these cables are still very susceptible to it. Twisted pair cables are the most cost-effective option of the three – mostly due to their lower bandwidth capacity and high attenuation. There are two types of twisted pair cables:

Unshielded twisted pair (UTP)

‘Unshielded’ meaning it does not rely on physical shielding to block interference

Most commonly used cable of the two, often utilized for both residential and business use

There are several UTP categories, which increase in bandwidth as you move up the scale, for example:

CAT1 = up to 1Mbps | CAT2 = up to 4 Mbps | CAT5e = up to 1Gbps

Shielded twisted pair (STP)

‘Shielded’ with a foil jacket to cancel any external interference

Used primarily for large-scale enterprises, high-end applications, and exterior cabling that will be exposed to environmental elements.
