Difference between Unix and Linux :

You might have heard of Unix, The operating system developed in the 1970s at Bell Labs by Ken Thompson, Dannis Ritchie and other team members. Unix and Linux are almost similar in few many ways, and we can say Linux was originally founded with the based on Unix.

Bootloader: Bootloader is managing the boot process of the computer system, In simple language, we can say it starts the operating system after Power Button command and run till the Login screen page comes.
