The term "boot" has been used in this sense since at least 1958. [15] IBM System/3 console from the 1970s. Program load selector switch is lower left; Program load switch is lower right. Other IBM computers of that era had similar features. For example, the IBM 1401 system (c. 1958) used a card reader to load a program from a punched card. The ...
Booting is the process of starting a computer, specifically with regard to starting its software. The process involves a chain of stages, in which at each stage, a relatively small and simple program loads and then executes the larger, more complicated program of the next stage.
Cold start (or cold boot) may also refer to a booting process of a single computer (or virtual machine). [2] In this case services and other startup applications are executed after reboot. The system is typically made available to the user even though startup operations are still performed and slow down other operations.

This program may itself be a small program designed to load a larger and more capable program, i.e., the full operating system.
A generic term that refers to a high-performance input/output (I/O) architecture that is implemented in various forms on a number of computer architectures, especially on mainframe computers. chipset. Also chip set. A group of integrated circuits, or chips, that are designed to work together. They are usually marketed as a single product.
The boot ROM is either placed on the same die as the CPU or is an external ROM chip. On modern systems, the boot ROM (whether integrated into CPU or external ROM chip) is usually use NOR flash which supports execute in place. The boot ROM will then initialize the hardware busses and peripherals needed to boot.
