Data Transmission Quiz

Which mode of transmission allows for bidirectional communication but not at the same time?

• Simplex

• Multiplexing

• Half duplex

• Full duplex

What is the advantage of using full-duplex mode of transmission?

• It requires only one communication channel

• It is less reliable than simplex mode

• It allows for simultaneous bidirectional communication

• It is the most cost-effective mode

In which mode of transmission can only one bit be transmitted at a time?

• Serial data transmission

• Parallel data transmission

• Simplex mode

• Half-duplex mode

What is the purpose of packet switching in data transmission?

• To send data in both directions simultaneously

• To divide the channel capacity between signals

• To forward data packets from one network to another

• To deliver packets from one computer system to another

What is the protocol used for detecting and handling network collisions?

• UDP

• TCP/IP

• HTTP

• CSMA/CD

What is the function of a router in a network?

• To send data in both directions simultaneously

• To detect and handle network collisions

• To convert serial data to parallel data

• To forward data packets from one network to another

What is the technology used to send multiple signals over a single communications link at the same time?

• Transponders

• Traffic Routing

• Packet switching

• Multiplexing

What is the main disadvantage of using half-duplex mode of transmission?

• It is less reliable than simplex mode

• It is the most expensive mode

• There is a delay between transmission and reception

• Both devices cannot transmit at the same time

What is the advantage of using parallel data transmission over serial data transmission?

• Transmission is faster than serial transmission

• It is typically cheaper and easier to set up

• It requires only 2 wires compared to 8 or 16 in parallel

• It is less prone to interference over long distances

What is the purpose of checksum in a data packet?

• To identify the location of other devices based on monitoring source and destination addresses

• To arrange data from multiple packets into the correct order

• To indicate which protocol has been used to form the packet

• To verify that the data that was sent matches the data that was received
