Detailed explanation-1: -In a network, If P is the only packet being transmitted and there was no earlier transmission, which of the following delays could be zero? Explanation: Since there is no other packet to be transmitted, there is no need for a queue. Therefore, the delay caused due to the queuing would be none i.e. 0.
Detailed explanation-2: -Packet transmission delay is the time taken by the physical layer at the source to transmit the packets over the link. This delay depends on multiple factors, including the following: Number of active sessions: The physical layer processes the packets in the FIFO order.
Detailed explanation-3: -Latency is the delay between a user’s action and a web application’s response to that action, often referred to in networking terms as the total round trip time it takes for a data packet to travel.
Detailed explanation-4: -When a packet arrives at a router interface to be forwarded, it has to wait its turn in a queue. Earlier packets need to be sent out first. This results in queuing delay, which varies depending on traffic conditions.
Detailed explanation-5: -My book defines queuing delay as the time the packet waits to be transmitted onto the link. It defines transmission delay as the amount of time required to push all of the packet’s bits onto the link.
