One megabyte is equal to how much?
- A.1024 gigabyte
- B.1000 byte
- C.1024 kilobyte
- D.1024 terabyte
Correct answer
Explanation
The correct answer is C, 1024 kilobyte. Computer memory is counted in powers of two because a binary machine addresses memory in twos, so each step up the ladder is 1024 of the unit below it, not 1000. One byte is 8 bits, 1024 bytes make a kilobyte, 1024 kilobytes make a megabyte, 1024 megabytes make a gigabyte and 1024 gigabytes make a terabyte, which is then followed by the petabyte, exabyte, zettabyte and yottabyte. So a megabyte is 1024 kilobytes, or 1048576 bytes. Option A is wrong because 1024 gigabytes make a terabyte, a unit far larger than a megabyte. Option B is wrong because 1000 bytes is roughly a kilobyte, and even that is only the decimal approximation. Option D is wrong because 1024 terabytes make a petabyte. Exam tip: the ladder is bit, byte, KB, MB, GB, TB, PB, and each step is 1024, that is 2 to the power 10.
