Answer:
Synchronous data transmission is a data transfer method in which a continuous stream of data signals is accompanied by timing signals (generated by an electronic clock) to ensure that the transmitter and the receiver are in step (synchronized) with one another. The data is sent in blocks (called frames or packets) spaced by fixed time intervals.
Answer:
69.08265412 milliseconds
Explanation:
Lets first convert 7 MiB to bits
bits
Now convert bits to Gbits
Gbits
Queuing Delay = Total size/transmission link rate
Queuing Delay= 
seconds
Delay of packet number 3 = 
seconds
or 
milliseconds
Bertha should use end roll technique so that she doesn't miss the initial action of a drama.
b. end roll
<u>Explanation:</u>
End roll is a simple method to decide whether the film is pushing ahead or not. When you utilize the film advance to wind the film, you essentially need to check if the handle on the left (that you use to rewind the film) is turning.
In the event that it turns, great, it implies that the film is appropriately locked in. So Bertha should utilize the end move strategy with the goal that she doesn't miss the underlying activity of a dramatization.
