Q1:

When an input electrical signal A=10100 is applied to a NOT gate, its output signal is

A 01011

B 10001

C 10101

D 00101

E None of the above

ANS:A - 01011

A NOT gate (also often called Inverter) is a logic gate. Each NOT gate has only one input signal. Logically with NOT gates, the input and the output swap, so if you input 1 it outputs as 0; likewise if you input 0 it outputs as 1.
