Linux

Starting Linux

Electricity flows from the power supply to the clock. The clock is the timer, which makes sure all the different pieces of the puzzle are synchronized. Once the self check is done, UEFI starts up and calls the bootloader from memory to the processor. The boot loader then starts the Linux kernel. The Linux kernel takes over and starts systemd. systemd then starts your desktop and all the other applications that run on your computer.
