Computer storage uses bytes. One byte has eight bits, which is translated as two to the power of three, according to the binary system. 1,024 bytes make a kilobyte, which translates to two to the power of ten. The smallest file size that can be stored on a computer is four kilobytes, which equates to 8,192 bits. The prefix “kilo” means a thousand. There are 1,024 kilobytes in a megabyte, so there are 1,024*1,024 bytes in a megabyte, which equals 1,048,576.
