Packet and Circuit Switching

What is the purpose of a hop number in packet switching?

• To identify the length of the packet in bytes.

• To calculate the checksum value for each packet.

• To stop packets from clogging up routes that never reach their destination.

• To determine the source IP address of the packet.

Which information is NOT included in a packet header when using the TCP/IP protocol?

• Packet priority

• Source IP address

• Fragmentation offset

• Transmission protocol being used

What is the main advantage of circuit switching over packet switching?

• The circuit is always available whether in use or not

• The data transfer rate is faster

• It works better for real-time applications

• It allows for easy expansion of traffic usage

What is the purpose of a routing table in a network?

• To determine the source IP address of the packet

• To forward a package along the shortest route to reach its destination

• To identify the length of the packet in bytes

• To calculate the checksum value for each packet

What happens if a packet in packet switching reaches a hop number of 0?

• It will be reassembled at the destination

• It will be sent back to the source IP address

• It will be re-routed to a different destination

• It will be deleted when it reaches the next router

Which network type is NOT a common use of circuit switching?

• Public telephone networks

• Digital networks

• Private telephone networks

• Private data networks

What is the main disadvantage of packet switching?

• It is not very flexible

• It requires a greater bandwidth

• It does not work well with real-time data streams

• It always uses digital networks

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

• To identify the length of the packet in bytes

• To calculate the transmission protocol being used

• To ensure no errors have occurred during transmission

• To determine the source IP address of the packet

What is the main advantage of packet switching over circuit switching?

• It requires a longer time to establish a connection

• It works better for real-time applications

• It always uses a dedicated channel

• It allows for high data transmission
