In this post,we will learn about the Computer booting process, what is it and type of it and the ways by which we can  boot the system . So, First we need to understand what is booting ? when we turn on the system, there is an operation performed by the computer to load operating system automatically, that process is known as Booting Process .

It can be either 0 or 1.  so, when we combine 4 bits together , it is called as Nibble .                                                                  0, 1  -   b     - bit                                               4 bit-   -       - nibble                                              8bit  -  B      -  1 byte or 1 octet or 1 character                                              1024B-  KB  - 1 KiloByte                                              1024KB- MB- 1 MegaBy
