Which of the following reasons is true with respect to the statement of "The maximum throughput performance of slotted-ALOHA is about twice that of simple/pure-ALOHA"? because transmission can start only at the beginning of frames time periods in slotted ALOHA because collision detection is implemented (so transmitters stop transmitting if they find a collision) in slotted ALOHA O because the performance of slotted-ALOHA is not exactly twice that of simple ALOHA because slotted ALOHA stations can send their packets synchronously.

I need the answer as soon as possible

The 16-bit FCLA taught in class features a two-level design, i.e. level 1: use pi and gi signals to calcuate super signals, and level 2: use super signals Pi and Gi to calculate the carryout from the MSB. Now consider using FCLA to support 256-bit additions. How many levels will there be in your design? Why? Using gate delay as the unit of time, how many gate delays are needed for your 256-bit adder to output the carryout from its MSB?

Implement the following function with a8-to-1-line Multiplexer with threeselection lines? Draw the truth table and the corresponding block diagram for the MUX?F(A, B, C, D) = Σm ( 1, 3, 4, 11, 12, 13,14,15 )
