So we might think it is waste to employ two person for same task but it is not so. There are many <em>benefits in incorporating this technique</em>. Let us see those benefits one by one.

</em>
- <em>Lower amount of coding mistake
</em>
- <em>Learn from each other
</em>
- <em>Peer review enhance collaboration
</em>
Challenges expect to arise during pair-programming
-
Two heads are superior to one. On the off chance that the driver experiences a <em>hitch with the code</em>, there will be two of them who'll take care of the issue.
- Builds up your <em>staff's relational aptitudes</em>. Working together on a solitary venture encourages your group to welcome the estimation of <em>correspondence and collaboration. </em>

Answer:
a. Host A will retransmit neither segments
Explanation:
The options are:
a. Host A will retransmit neither segments
b. Host A will retransmit first segment
c. Host A will retransmit the second segment
d. Host A will retransmit both segments
The first acknowledgment is lost but the second acknowledgment arrives before the timer of the first segment expires, and hence the host A gets confirmation that Host B has received both the segments. And hence Host A will retransmit neither segments.
Answer:
The first question you should ask yourself before performing the repair is Option B. Can you find a replacement motherboard.
Explanation:
According to me, I would ask “Can you find a replacement motherboard”.
Because, Always the laptop charge will be more than the charge of a mother board, because motherboard is just a part and the laptop consists of other important parts too. So Option (a) is not the wise selection.
Let’s look into option D. Warranty period should be verified by us and not the technical person, because we have purchased and we have the warranty card.
Let’s look into option C. The technical person will already be well-versed with fixing solution and diagnosing problem. So service manual will be of not much use to him and he would want to make money out of fixing the problem, so we cannot expect him to teach us how to replace a motherboard.
