<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:
Liam could
1) Change the password
Be sure to change the password to a "strong" one (containing lots of characters, numbers, symbols) so that way the password would be difficult to guess.
2) Avoid logging onto social media on public computers or WiFi connections.
Using public WiFi leaves you vulnerable to someone accessing your information through Internet traffic. If you do use public computers, just make sure to log out.
3) Avoid giving out account information to friends and avoid opening suspicious links and emails.
Opening suspicious links or emails could allow malware to infect your computer the moment you open them. Friends can unknowingly share these links that are designed to steal information.
