Understanding Transmission Media

What is the primary function of transmission media in networking?

• To store data signals temporarily during transmission.

• To convert data signals from analog to digital format.

• To encrypt data signals for security purposes.

• The primary function of transmission media is to carry data signals between network devices.

During a technology workshop, Dhruv is explaining different types of transmission media used in networking. He asks the participants, "Which of the following is a type of guided transmission media?"

• Fiber optic cable

• Twisted pair cable

• Coaxial cable

• Wireless transmission

What is the main advantage of fiber optic cables over copper cables?

• Better resistance to electromagnetic interference.

• Higher bandwidth and faster data transmission over longer distances.

• Longer lifespan and less maintenance required.

• Lower cost and easier installation.

Aarush is setting up a new office network and needs to choose the right type of cabling. He is concerned about the potential for electromagnetic interference in the office environment. Which transmission medium should he avoid as it is most susceptible to electromagnetic interference?

• Shielded twisted pair (STP) cable

• Unshielded twisted pair (UTP) cable

• Fiber optic cable

• Coaxial cable

What does the term 'bandwidth' refer to in data communication?

• The physical distance between two network devices.

• The type of cable used for network connections.

• The amount of time data takes to travel across a network.

• The maximum data transfer rate of a network connection.

While setting up a new communication system for their remote village, Krish and Avni are exploring different types of wireless transmission methods. They want to know which type uses radio waves to ensure reliable connectivity.

• Satellite communication

• Microwave transmission

• Radio frequency transmission

• Infrared transmission

What is the maximum distance for effective data transmission over twisted pair cables?

• 50 meters

• 150 meters

• 200 meters

• 100 meters

What is the primary disadvantage of using coaxial cables?

• Easy installation in tight spaces.

• High durability in extreme conditions.

• Signal loss over long distances.

• Low cost compared to fiber optics.

Which transmission medium is best suited for high-speed internet connections?

• Satellite connections

• Twisted pair cables

• Fiber optic cables

• Coaxial cables

What is the role of repeaters in data communication networks?

• Repeaters store data packets for later transmission.

• Repeaters amplify and regenerate signals in data communication networks.

• Repeaters create new network connections between devices.

• Repeaters encrypt data for secure communication.
