*Answer can only contain numeric values

Digital Electronics NAT Level - 1 - Question 1

If the memory chip size is 256 x 1 bits, what is the number of chips required to make 1 up 1K byte of memory

Detailed Solution for Digital Electronics NAT Level - 1 - Question 1

1 byte = 8 bits
1K byte = 1024 bits
1K byte = 1024 x 8 bit
Number of chips =
The correct answer is: 32

*Answer can only contain numeric values

Digital Electronics NAT Level - 1 - Question 2

The number 6.25 in the decimal notation, when converted to the binary notation will read as ?

Detailed Solution for Digital Electronics NAT Level - 1 - Question 2

Hence, 6 =110
Now 0.25 x 2 = 0.50 → 0
0.50 x 2 = 1.00 → 1
0.00 x 2 = 0 → 0
Hence, 0.25 = 0.010 →1
Hence (6.25)₂ = 110.010
The correct answer is: 110.01
