+[[Category:Encyclopedia]]Hexadecimal code is another number system used by computers. While decimal (our normal number system) uses ten digits, and binary uses two digits (0 and 1), hexadecimal uses base 16.
-Hexadecimal code is essentially a shorthand version of binary code. While binary code works using base 2 units, hexadecimal uses base 16. Hexadecimal is used as a shorthand of binary because binary code is hard for humans to comprehend.
-Instead of using only 0's and 1's, or 0-9, hexadecimal uses 0-9 just like base 10, but also A-F. A=10, B=ll, and so forth. The most convenient method of converting binary to hexadecimal is to first separate the byte (8 digits) into 2 nibbles (4 digits). Then, convert each nibble into base 10, at which point 10-15 are changed into letters. That's it.
