Answer to Question 1

Ans: (c)

Answer to Question 2

Checksum checking (CC) works by computing a running total based on the byte values transmitted in a message block and then applying a calculation to compute the checksum value. A common technique is for checksum to add the decimal value of each byte in the message block to obtain a total. The total is then divided by 255. The remainder becomes the checksum value, which is attached to end of the message block being transmitted. The receiver also performs a checksum computation on the core message block received and compares its computed checksum with the checksum sent. If the two values are the same, the receiver assumes the transmission was error free. Checksum has a 99.6 percent probability of detecting errors in a transmission.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
