Transmission Media

What is transmission media?

• Transmission media refers to software used for data processing.

• Transmission media are the protocols governing data encryption.

• Transmission media are the physical pathways used for data transmission.

• Transmission media are the devices that store data temporarily.

Name two types of guided transmission media.

• Wireless signals

• Satellite links

• Coaxial cables

• Twisted pair cables, Fiber optic cables

What is the primary characteristic of unguided transmission media?

• Lack of physical guidance for signal transmission.

• Increased signal strength through physical barriers.

• Dependence on specific frequencies for communication.

• Use of cables for signal transmission.

Define the term 'bandwidth' in the context of transmission media.

• Bandwidth is the maximum data transfer rate of a transmission medium, measured in bits per second.

• Bandwidth is the amount of time a signal takes to travel from source to destination.

• Bandwidth refers to the physical size of a transmission cable.

• Bandwidth is the number of devices that can connect to a network simultaneously.

What is the difference between simplex and duplex transmission modes?

• Simplex is faster than duplex transmission.

• Both simplex and duplex allow two-way communication.

• Simplex allows one-way communication; duplex allows two-way communication.

• Simplex allows two-way communication; duplex allows one-way communication.

Give an example of a transmission medium that uses a strand of glass.

• Fiber optic cables

• Twisted pair cables

• Coaxial cables

• Wireless signals

What are the advantages of using wireless transmission media?

• Limited range and coverage

• High installation complexity

• Increased interference and noise

• Advantages of using wireless transmission media include mobility, ease of installation, cost-effectiveness, and flexibility.

Explain the term 'transmission mode'.

• Transmission mode is the physical distance between devices.

• Transmission mode is the method of data transmission between devices, including simplex, half-duplex, and full-duplex.

• Transmission mode is a type of network security protocol.

• Transmission mode refers to the speed of data processing.

What is the role of a network cable in guided transmission?

• The role of a network cable in guided transmission is to provide a physical medium for data signals to travel between devices.

• To convert digital signals into analog signals.

• To store data temporarily during transmission.

• To amplify the data signals for longer distances.

How does the distance affect the choice of transmission media?

• All transmission media perform equally regardless of distance.

• Longer distances can use cheaper media like copper without issues.

• Distance has no impact on the choice of transmission media.

• Longer distances typically require higher quality media like fiber optics to reduce signal loss and maintain integrity.
