Question

If a computer has eight-byte addressability and needs three bits to access a location in memory, what is the total size of memory in bytes?

Answer 1

64 byte of memory

Step-by-step explanation:

The computer has 8 bytes addressability and the memory only requires 3 bits to access its entire memory size. Remember that a computer is an electronic device and it stores data and receives instructions in binary of 1 and 0. So for an eight-byte addressable computer,

total memory size = 2^(3 bits) x 8 (computer's addressability)

= 8 x 8

= 64 bytes of memory.
