Hexeditor
Purpose
The purpose of a hex editor is to be able to view a page in hexadecimal instead of standard ASCII. This is the main way to be able to create a binary without needing to type extended ascii, or program at all. Hex editors are also used to convert decimal to hexadecimal vice versa.
Counting in hexadecimal is different from counting in decimal.
