Q1:

The hexadecimal number 4B16 is transmitted as an 8-bit word in parallel. What is the time required for this transmission if the clock frequency is 2.25 MHz?

A 444 ns

B 444 s

C 3.55 s

D 3.55 ms

ANS:A - 444 ns

Because the clock pulse of 4-bit transmit the data of 8-bit word
in parallel mode.
And this transmission done at 2.25mhz frequency.
we know that;
f=1/t
and we can find the time required for this transmission by the clock pulse
