<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:
BitLocker is a full volume encryption feature included with Microsoft Windows versions starting with Windows Vista. It is designed to protect data by providing encryption for entire volumes. By default, it uses the AES encryption algorithm in cipher block chaining (CBC) or XTS mode with a 128-bit or 256-bit key.
Answer:
While CLOB/NCLOB types may seem attractive, they are not nearly as efficent as [N]VARCHAR for most of the functions you would usually want to run on them, and anyone who can't comment in 2000 or 4000 characters isn't likey to generate a comment you'd want to use anyway.

Answer:
The ethernet protocol IEEE 802.3 is only meant for cable networks.
Explanation:
In this scenario, there are two types of networks, namely;
LAN and WLAN.
A LAN (local area network) is a network within a small area like a building, i which its workstation are connected using cables. The cabled network instantly use a protocol called Ethernet also known as IEEE 802.3.
WLAN (wireless local area network) is a small area network just like the LAN, but the difference is that its workstation are connected wireless (without cable). wireless networks uses wifi or 802.11a/n/g to connect to the network.
So, the ethernet protocol represents the cabled network, Wifi represents the wireless network.
