Answer:
t= 8.7*10⁻⁴ sec.
Explanation:
If the signal were able to traverse this distance at an infinite speed, the propagation delay would be zero.
As this is not possible, (the maximum speed of interactions in the universe is equal to the speed of light), there will be a finite propagation delay.
Assuming that the signal propagates at a constant speed, which is equal to 2.3*10⁸ m/s (due to the characteristics of the cable, it is not the same as if it were propagating in vaccum, at 3.0*10⁸ m/s), the time taken to the signal to traverse the 200 km, which is equal to the propagation delay, can be found applying the average velocity definition:
If we choose x₀ = 0 and t₀ =0, and replace v= 2.3*10⁸ m/s, and xf=2*10⁵ m, we can solve for t:
⇒ t = 8.7*10⁻⁴ sec.
Answer:
Decode. To change how information is represented so that it can be read by a person.
Explanation:
Decoding is the ability to apply your knowledge of letter-sound relationships, including knowledge of letter patterns, to correctly pronounce written words. Understanding these relationships gives children the ability to recognize familiar words quickly and to figure out words they haven't seen before.
Answer:
consumer-to-consumer auction site
Explanation:
The best type of purchase for this scenario would be a consumer-to-consumer auction site. These sites allow anyone to make a publication selling their product. This publication can be seen by anyone around the world. It is the best way of finding the cheapest prices for a specific item. The condition of the items on these sites can vary. The majority of the time they are used items in good conditions, but can also be new items or very worn out items being sold for parts.
Answer:
It is done to avoid collision among the channel.
Explanation:
CSMA/CD stands for carrier sense multiple access/collision detection.
It is a media access protocol that tells the devices how to respond when a channel is used simultaneously by two devices. The main purpose is to manage the transmission when a collision is encountered.
In the given scenario when the channel is detected idle, the station does not transmits second frame in order to avoid collision. CSMA/CD protocol is designed so that after transmission of first frame, second frame transmission is started at step 2 instead of step 1.
Following is given the flow chart that depicts the working of the protocol CSMA/CD:
