Explain how propagation delay affects the speed of modern PCs?

A: I wouldn't call propagation delay that applies to other media. for a PC delay are parasitic in nature mostly layout. But the real and actual delay is inherited from the I/O which is the soul of PC speed. No matter how fast a PC is internally it must service those interrupts and that is really the delay actually


What is the time for the TV signal to come from the TV mast to your TV set?

The signal will move down the cable at from about 1/3 the speed of light to about 9/10 the speed of light, depending on the type of cable used. If there is a booster amplifier in the cable between the antenna and the TV set this will add more delay. You will need to know the length and types of cable used (and look up their signal propagation speed) as well as the delay of your booster amplifier if your system has one to calculate the answer to your question.


A light signal is travelling through a fiber. What is the delay in the signal if the length of the fiber-optic cable is 10m 100m 1km (assume a propagation speed of 2 x 108 ms)?

To calculate the delay of the light signal in the fiber-optic cable, use the formula ( \text{Delay} = \frac{\text{Length}}{\text{Propagation speed}} ). For a length of 10m, the delay is ( \frac{10, \text{m}}{2 \times 10^8, \text{m/s}} = 5 \times 10^{-8}, \text{s} ) (50 ns). For 100m, the delay is ( 0.5 \times 10^{-6}, \text{s} ) (500 ns), and for 1km, it’s ( 5 \times 10^{-6}, \text{s} ) (5 µs).


What causes packet delay?

Packet delay is caused by several factors, including propagation delay, transmission delay, queuing delay, and processing delay. Propagation delay occurs as packets travel through the medium, while transmission delay is the time taken to push all packet bits onto the network. Queuing delay happens when packets wait in line at routers or switches due to network congestion, and processing delay is the time taken by devices to process the packet headers and make forwarding decisions. Each of these factors can contribute to the overall delay experienced in data transmission.


How can Propagation delay be avoided in a parallel adder?

The parallel adder which we use in the digital circuits ,the carry output of each full adder stage is connected to the carry input of the next higher order stage.therefore,the sum and carry outputs of any stage cannot be produced until the input carry occurs; This leads to a time delay in the addition process.This delay is known as carry propagation delay. to the second question the propagation delay can be avoided in the binary parallel adder with the help of look ahead carry generator .............................................................................................................................
