B, plants and weather are part pf nature.
Answer:
QoS
Explanation:
We could use a blacklisting or a MAC filtering to remove from the network, and in this way, we're going to get a high portion of bandwidth, but other must work too, and the whitelisting have almost the same function, but QoS Quality of service is specifically for these cases where we need high bandwidth for a video conference, we can make this with some tools or techniques like jitter buffer and traffic shaping.
Explanation:
In computer science, a sorting. algorithm is an algorithm that puts elements of a list in a certain order. The most frequently used orders are numerical order and lexicographical order. Efficient sorting is important for optimizing the efficiency of other algorithms that require input data to be in sorted lists
<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:
85
Explanation:
0 + 64 + 0 + 16 + 0 + 4 + 0 + 1 = 85
