Q & A

What is data transmission media?

Data transmission media refers to the means by which signals are transmitted from a sender to a receiver, enabling communication over distances.

What are the two main categories of data transmission media?

The two main categories are guided media and wireless media.

What distinguishes guided media from wireless media?

Guided media involves physical pathways for signals, such as cables, while wireless media transmits signals through the air.

What are the characteristics of twisted pair cables?

Twisted pair cables consist of two wires twisted together, are inexpensive and easy to install, but have limited range and are generally used for local installations.

What is coaxial cable, and where is it commonly used?

Coaxial cable is a versatile cable commonly found in television distribution systems and LAN networks, offering good performance over longer distances.

What are the advantages of fiber optic cables?

Fiber optic cables offer high speed, high frequency, and require less physical space due to their thin structure, though they are relatively expensive.

What is microwave transmission, and what is its frequency range?

Microwave transmission is used for long-distance telecommunications, typically operating in the frequency range of 1 to 10 GHz.

How is broadcast radio classified as a type of wireless media?

Broadcast radio is classified as wireless media because it transmits signals over the air, commonly used for FM radio and television.

What applications use infrared as a transmission medium?

Infrared is often used for short-range communication, such as in remote controls for TVs and air conditioners.

What are the main disadvantages of fiber optic cables?

The main disadvantage of fiber optic cables is their high cost compared to other types of transmission media.
