Computer memory
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 210 = 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 220 bytes or 1024KB, which is 1,048,576 bytes. One gibibyte means 230 bytes or 1024MB.
