Thousand (10 to the 3rd power). Abbreviated "K." For technical specifications, it refers to the precise value 1,024 since computer specifications are based on binary numbers. For example, 64K means 65,536 bytes when referring to memory or storage (64x1024), but a 64K salary means $64,000. The IEEE uses "K" for 1,024, and "k" for 1,000.
