Memory Sizes Explained: Gigabytes, Terabytes, and Petabytes in Context
The unit megabyte is commonly used for 1000 (one million) bytes or 1024 bytes. The interpretation of using base 1024 originated as technical jargon for the byte multiples that needed to be expressed by the powers of 2 but lacked a convenient name. As 1024 (2 ) approximates 1000 (10 ), roughly corresponding to the SI prefix kilo-, it was a convenient term to denote the binary multiple. In 1998, the International Electrotechnical Commission (IEC) proposed standard… WebUsable memory is a calculated amount of the total physical memory minus "hardware reserved" memory.
