Data Transmission 2

What technique allows multiple signals to travel simultaneously over a single communication channel?

• Multiplexing

• Error Checking

• CSMA/CD

• Packets

What is the method called that divides data into packets for transmission over a network?

• Circuit Switching

• Packet Switching

• Multiplexing

• Bandwidth

What does CSMA/CD stand for in networking?

• Carrier Sense Multiple Access with Collision Detection

• Circuit Switching Multiple Access with Collision Detection

• Carrier Sense Multiplexing Access with Collision Detection

• Circuit Sense Multiple Access with Collision Detection

Which of the following is NOT included in the header's control information?

• Synchronization

• Packet number

• Parity check

• Protocol

What is the purpose of the header in a data packet?

• To contain control information

• To store the actual data

• To perform error checking

• To pad the packet

What does a higher bandwidth connection provide compared to a lower bandwidth connection?

• Faster data speed

• More room for data

• Longer cable length

• More channels

What determines the speed at which data flows along a cable?

• The bandwidth

• The speed of electricity (or light)

• The length of the cable

• The number of connected devices

What does a node do while sending data in CSMA/CD?

• Stops listening to the Bus

• Continues to listen to the Bus

• Sends a confirmation signal

• Waits for a response

What is the primary function of a router in a network?

• To encrypt data

• To provide power to devices

• To connect different networks

• To store data

In CSMA/CD how long does a device wait after a collision before retransmitting data?

• Immediately

• 1 second

• Pre-agreed time

• Random time
