Chapter 6, Problem 1RQ

Explanation of Solution

Telecommunication medium:

• Telecommunication medium is the interchange of data over significant distances by electronic devices which refer to data, video, and voice transmission.
• It includes a wide range of data transmitting technologies, such as microwave communications, satellites, telephones, radio and television broadcasting, telegraphs and internets...

Explanation of Solution

Types of telecommunication medium:

• Twisted-pair wire
• Fiber-optic cable
• Coaxial cable.

Twisted-pair wire:

• Twisted-pair wire is somewhat literally a pair of insulted wires that are twisted together to help decrease noise from the external sources.
• It is the most cost-effective option of the three but also brings about high attenuation and lower bandwidth.
• There are two types of twisted-pair wires. They are unshielded and shielded twisted pair.

Fiber-optic cable:

• It contains optical fibers for transferring data via light, instead of transferring data over copper wires...
