Explanation / Answer

Q1) Answer :15

explanation:

in a 4 bit cell max value would be : 1111

decimal value of 1111 is 15

Q2)Answer : 7

explanation:

in 2's complement MSD 1 bit is take for sign

Msd value is 0 then positive , 1 the negative

now we have 3bit cells remaing ,

max value is :111 in decimal 7

Q3) Answer :255

explanation:

in a 8 bit cell max value would be : 11111111

decimal value of 11111111 is 255

Q4)Answer : 127

explanation:

in 2's complement MSD 1 bit is take for sign

Msd value is 0 then positive , 1 the negative

now we have 7 bit cells remaing ,

max value is :1111111 in decimal 127
