In computing, booting is the process of starting a computer as initiated via hardware such as a physical button on the computer or by a software command, first described in the 1950s as the "bootstrap technique." After it is switched on, a computer's central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed. This may be done by hardware or firmware in the CPU, or by a separate processor in the computer system. On some systems, a power-on reset (POR) does not initiate booting, and the operator must initiate booting after POR completes. IBM uses the term Initial Program Load (IPL) on some product lines.
