The numbers that computers use can get very large. To make it easier, the unit K (for kilobyte) or Ki (for kibibyte) can be used. In computer memory numbers are powers of two. One Kibibyte is two to the power of 10, that is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 and written as 2 = 1024 bytes. For example, 64 Kibibytes, written as 64KiB or 64KB, of memory is the same as 65,536 bytes (1,024 × 64 = 65,536). For larger memory capacities, the units "megabyte" (MB) or "mebibyte" (MiB) and "gigabyte" (GB) or "gibibyte" (GiB) are used. One megabyte of computer memory means 2 bytes or 1024KB, which is 1,048,576 bytes. One gibibyte means 2 bytes or 1024MB.
