Answer:
G7 (option B)
Explanation:
Cell references are written as: Letter | number
(column | row)
For example: If a cell was in the first column, [column a], and the tenth row [10], the cell would be named "A10"
The seventh letter in the alphabet is G, and we know that the 7th row is the number 7. So, the cell has the reference of "G7"
Answer: Atomic operations
Explanation: Atomic operations are the process in which are related with the programs which execute in the independent manner and having no relation with other processes or functions.
It is helpful operation in the parallel processing system.The operation assures about being carried out at rapid rate and do not face any deadlock during execution.This does not alter the rate of the system.
Answer:
the answer is going to be district b
<u>Solution:</u>
a) False. Piggyback is used only for efficiency. If there's no data packet to be piggybacked to, then B will just send the acknowledgement packet.
b) False. It is the size of the receiver's buffer that's never changed. RcvWindow is the part of the receiver's buffer that's changing all the time depending on the processing capability at the receiver's side and the network traffic.
c) The given statement is True.
d)
False. The sequence number of the subsequent segment depends on the number of 8-byte characters in the current segment.
e) True. Every TCP segment has a current value of rwnd in the receive window.
f) False. Next_RTT = alpha * last_estimated_RTT + (1-alpha)*newly_collected_RTT_sample. In this case even though the last sampleRTT which is the newly_collected_RTT_sample is 1sec, the next_RTT still depends on alpha and last_estimated_RTT. Therefore, the next_RTT is not necessarily greater than 1sec.
g)
False. The acknowledgement number has nothing to do with the sequence number. The ack. number indicates the next sequence number A is expecting from B.
Answer:
The answer is (a).Presentation Layer
Explanation:
This layer is located at the 6th level of the OSI model, responsible for delivering and formatting the information to the upper layer for further processing. This service is needed because different types of computer uses different data representation. The presentation layer handles issues related to data presentation and transport, including encryption,translation and compression.
