Likewise, people ask, what happens when you first turn on a computer?
The first thing a computer has to do when it is turned on is start up a special program called an operating system. The BIOS chip tells it to look in a fixed place, usually on the lowest-numbered hard disk (the boot disk) for a special program called a boot loader (under Linux the boot loader is called Grub or LILO).
Is it bad to turn off your computer with the power button?
Just press the power button and hold it down. After a few seconds, the power will be cut to your computer and it will suddenly shut down. This is normally a bad idea, as it can lead to lost data, file system corruption, and other issues.
