When a computer is booted, it starts up. This is the process of starting up the computer and getting it ready to use. The first thing that the computer does is load its operating system, which is a set of instructions that tells the computer what to do next. After the operating system loads, the computer will start up its applications and start working.
Computers Pull Themselves Up by Their Bootstraps
The word “boot” is a shortened form of the word “bootstrap,” whose noun form refers to the strap on a pair of boots that you can grab and pull to help you get the piece of footwear onto your trotter. The verb form, “bootstrapping,” refers to the English idiom “pull oneself up by one’s bootstraps.” Picture a person lifting themselves into the air by simply reaching down and tugging on their waders—a miraculous sight for sure. The metaphor illustrates the idea of a person achieving a goal that would seem impossible without help from someone else.
So what does this have to do with computers? Before you can use your phone or PC, the device’s numerous pieces of hardware and software, like the CPU and operating system, need to be powered or loaded in the correct order. If overseeing that critical chain of events was up to you, every power cycle would be a difficult and tedious chore.
Instead, all you have to do is press the power button, and a small program called the bootloader springs into action coordinating the process, thereby allowing the device to “get itself off the ground” so to speak. In this way, the computer or smartphone can be thought of as having “pulled itself up by its bootstraps” or, for short, “booted.”
So while you might say “I booted my computer” or “I rebooted my router,” it’s technically the device, not you, which can claim the miraculous feat of booting.
