I am trying to work on this question but i have no clue on how to do this could you explain how these question can be answered and explain the answers

stop and wait 1. Describe the operation of stop-and-wait. 2. Suppose that we are doing stop-and-wait. Further suppose o Packets are 500 bytes o Our average bit rate is 5 Mbps o The one-way propagation delay is 100 ms, d. How long from when we start to send until the entire packet makes it onto the wire? e. How long from when we start to send until the packet makes it tothe receiver? f f we pretend that a are extremely tiny so that they have have no transmission delay), how long from when we start to send until we receive an acknowledge ent g. In the time interval that you've calculated during the p ous interval what fraction of the time was the sender actively pushing bits onto the wire? We call this value our utilization, because it defines ho well we're actualy W using (i.e., utilizing) the wire.

Explanation / Answer

Question:1

Description of stop-and-wait: Stop-and-Wait is basically a type of flow control. In this flow control, sender send the messeage to receiver by dividing the message into multiple frames. Sender send frames to the receiver, and after sending frame, sender waits for the acknowledgement before sending the next frame to receiver. In this
flow control we have following two operations:

i) Sender send a single frame at a time to the receiver.
ii) Receiver send acknowledgement to the sender as it receive the frame.

Advantages of Stop-and-Wait flow control:
i) Its very easy flow control.
ii) It make sure that receiver receive the frame before sending the next frame.

Disadvantages of Stop-and-Wait flow control:
i) Its slow as at a time single frame is send.
ii) Each time sender have to wait for the acknowledgement from the receiver side. it also make the complete flow slow.
