Circuit Switching, Packet Switching, and Message Switching

What is the main characteristic of circuit switching in data transmission?

• Data takes any available path

• Data follows a dedicated path from start to end

• Data is stored at each node before forwarding

• Data is split into datagrams

In packet switching, how are data packets transmitted across the network?

• Using a dedicated pathway

• Following a fixed path determined at the beginning of the session

• By taking any available path to reach the destination

• Using the store and forward technique

Which switching method is best suited for time-sensitive applications like real-time voice calls?

• Circuit Switching

• Packet Switching

• Message Switching

• Connectionless Packet Switching

What is the role of switches in message switching?

• To direct each packet individually without holding it

• To establish a continuous communication channel between sender and receiver

• To hold and forward packets only after all packets in a message are received

• To guarantee a consistent connection using packet prioritization

In which switching technique does each data packet follow its own path to the destination, possibly arriving out of order

• Circuit Switching

• Packet Switching

• Message Switching

• Connection-oriented Packet Switching

imary protocol used for packet switching over the internet is:

• Ethernet

• Transmission Control Protocol (TCP)

• User Datagram Protocol (UDP)

• Internet Protocol (IP)

Which of the following is true about connectionless packet switching?

• A dedicated session is established before data transfer

• Packets are transmitted along the same path in order

• Data packets are sent independently without a pre-set route

• Error checking is prioritized to ensure accuracy

What is the purpose of the "store and forward" method in message switching?

• To allow each packet to find its own route

• To retain packets at each switch until all parts of a message are received

• To connect the sender and receiver in a direct path

• To expedite the process by bypassing switches

Which of the following accurately describes the process in circuit switching?

• Data is fragmented and reassembled at the destination

• Data takes the same, dedicated path and cannot be shared during transmission

• Data is transmitted through a combination of multiple paths

• Data is stored at each switch and forwarded when ready

A major drawback of circuit switching for data networks is:

• It requires a complex routing system

• It uses excessive bandwidth by holding the path during the entire transmission

• It may result in unordered data packets

• It causes packets to be dropped when errors are detected
