Answer:
a. Checksum
Explanation:
Based on the information provided within the question it can be said that the field that represents this information is called the Checksum. Like mentioned in the question this refers to a value that represents the amount of bits in a certain transmission message. This is done in order to make sure that the amount of bits that were sent match the amount that were received in order to make sure that no data was lost in transit that would cause high-level errors.
Maybe 7411 or someones birthday in the family
Lowercase a is decimal 97 ; upper case is decimal 65
It's easier to think of them in octal, however: a = octal 141, and A is octal 101
octal to binary is easy, each digit is three bits.
141 = 001 100 001
101 = 001 000 001
So, how many bits are changed above?
Decrease. Think like this, if you were standing in the ocean getting hit by waves, frequency would be how many waves hit you in a certain amount of time. If there were lots of little waves hitting you the number of waves (the frequency) would be high, whereas big waves are slower and take more time to reach you so you would get hit by less of them in the same time frame. The less frequent, the longer the wave.
