Line 1:
[[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 like binary, or 0-9 like decimal, hexadecimal uses 0-9 just like base 10, but also A-F. A=10, B=ll11, and so forth. The most convenient method of converting binary to hexadecimal is to first separate the bytebinary (8 digits)number into 2string nibblesof (4 digits). Then, convert each nibblegroup into base 10, at which point 10-15 are changed into letters. That's it.
 
Ex.
10010110 10010111
1001 0110
2^03+2^3 0 2^2+2^1+2^20
8+1 9 54+2+1
9 95 7
97
