Computers store text as numbers, and hex shows the numbers in base 16, rather than decimal.
Hex or base 16 or hexadecimal may be a numeral system that uses 16 symbols. The symbols include 0-9 and a-f (sometimes A-F). An example of a hexadecimal number is 3BF2. computing applications can use hexadecimal for binary coding in computing and digital electronics. the first use of hex may be a more people friendly thanks to represent the worth .
While computers work with binary data, it are often difficult for humans to figure with an outsized number of digits. Humans typically use a base 10 system, while for computer applications it's easier to figure with hexadecimal than decimal.
As hex saves space (either paper space or screen space), you'll more efficiently use hex rather than an outsized number of ones and zeros. you'll also go from hex back to binary bits if needed. for instance A is 1010.
Hex numbers represent large numbers compactly and are utilized in programming as computers use bytes as a unit of data . In hex you would like two digits where you would like 8 binary digits to represent a byte.
Hexadecimal is additionally utilized in the Red-Green-Blue color system in computers. Red, green, and blue are each represented by a byte that's two hex digits. An RGB color uses six hex digits. Hexadecimal is additionally commonly wont to represent memory addresses.
