What is the exact number of bytes in system of memory that contains (a) 64K bytes (In Binary) (b) 32M bytes

64 K bytes = 65536 bytes

32 M bytes = 33554432 bytes

Explanation:

The question expect the number of bytes in binary instead of decimal. So this is important to understand that:

1K bytes = 1024 bytes (in binary)

Therefore,

64 Kb = 64 x 1024 = 65536 bytes

Using the similar calculation logic, we know

1M bytes = 1024 x 1024 = 1048576 bytes (in binary)

Therefore,

32 M bytes = 32 x 1048576 = 33554432 bytes
