A byte is 2³ bits. A megabyte is 2²0 bytes. How many bits are in a megabyte?

Question

A byte is 2³ bits. A megabyte is 2²⁰ bytes.

Write the answer as a power of 2.

Answer 1

 

A kilobyte is 2¹⁰ = 1024 bytes

A megabyte is the square of the above, 2²⁰ which equals 1,048,576 bytes.

 

Accordingly, that's 8,388,608 bits = 2²³ bits.

 

Did you know that there was a time, c. 1956-1964, when a byte was just six bits (IBM 704/709/7094 computer era)?
