Boot is short for bootstrap [1] [2] or bootstrap load and derives from the phrase to pull oneself up by one's bootstraps. [3] [4] The usage calls attention to the requirement that, if most software is loaded onto a computer by other software already running on the computer, some mechanism must exist to load the initial software onto the ...
In computer technology, the term bootstrapping refers to language compilers that are able to be coded in the same language. (For example, a C compiler is now written in the C language. Once the basic compiler is written, improvements can be iteratively made, thus pulling the language up by its bootstraps).
Network booting, shortened netboot, is the process of booting a computer from a network rather than a local drive. This method of booting can be used by routers, diskless workstations and centrally managed computers (thin clients) such as public computers at libraries and schools.
A bootloader, also spelled as boot loader [1] [2] or called bootstrap loader, is a computer program that is responsible for booting a computer. If it also provides an interactive menu with multiple boot choices then it's often called a boot manager .
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.
The term boot comes from the idea of lifting oneself by one's own bootstraps: [5] the computer contains a tiny program (bootstrap loader) which will load and run a program found on a boot device. This program may itself be a small program designed to load a larger and more capable program, i.e., the full operating system.
The system partition and the boot partition (also known as the system volume and the boot volume) are computing terms for disk partitions of a hard disk drive or solid-state drive that must exist and be properly configured for a computer to operate. There are two different definitions for these terms: the common definition and the Microsoft ...
For example in a system with an i.MX7D processor and a bootable device which stores the OS (including U-Boot), the on-chip boot ROM sets up the DDR memory controller at first which allows the boot ROM's program to obtain the SoC configuration data from the external bootloader on the bootable device.
