Question

a computer has 5 terminals and each terminal is capable of four distinct positions including the rest what is the total number of signals that can be made​

Answer 1

Step-by-step explanation:

Ans.

There are 5 terminals and each have 4 distinct positions .

It means that there can be 4^5 signals since each 5 has 4 different positions (4 x 4 x 4 x 4 x 4) =1024

But since the rest position is also included therefore subtract 1 when all signals will be in rest

So, 1024 - 1 = 1023 Ans.

Answer 2

Answer:

1023 4 to the power 5- minus 1
