Answer: the correct answer is D. Spectrum Analyzer tool
Explanation:
A spectrum analyzer is a piece of electronic equipment that is used to gauge the magnitude (amplitude or strength) of a given input signal set against the full frequency range of the instrument. It is mainly used to measure the strength of the range of known and unknown signals.
A smart way of moving money from one personal banking account directly to another account is called EFT or electric fund transfer. There is a maximum clearance time of 24 hours for transfer. The most widely-used program is Direct Deposit, in which payroll is deposited straight into an employee's bank account initiated through an electronic terminal, including credit card, Therefore, the following<span> statement regarding EFT is false?</span>

The actions that one need todo or perform FIRST is to backup the hard drive.
<h3>What causes a SMART error?</h3>
A composition of bad blocks can be a tool that can lead to a SMART error, or when the drive of the system's temperature is known to have gotten too high as a result of poor ventilation or other environmental factors.
Note that The actions that one need todo or perform FIRST is to backup the hard drive. because by doing so, one can be able to retrieve information back.
Hence the answer is correct.

Answer:
Basic auth is an authentication where username and password are sent with an HTTP request unencrypted (just base64 encoded).
OAuth is a scheme whereby you perform a login at an IAM server, which gets you a token, and then you provide the token with requests to another server.
<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.
