What is combinational logic?

Combinational logic is a type of digital logic where the output is solely determined by the present input.

What is the difference between combinational logic and sequential logic?

Combinational logic does not have memory and the output is only dependent on the present input, while sequential logic has memory and the output depends on both the present input and the history of the input.

Where is combinational logic used in computer circuits?

Combinational logic is used in computer circuits to perform Boolean algebra on input signals and on stored data.

Give an example of a computer circuit that uses combinational logic.

An arithmetic logic unit (ALU) that does mathematical calculations is constructed using combinational logic.

What are some other circuits used in computers that are made using combinational logic?

Other circuits made using combinational logic include half adders, full adders, half subtractors, full subtractors, multiplexers, demultiplexers, encoders, and decoders.
