The definition of Bit =
"The term bit or bits comes from combining the words BInary and digIT. In computing, a bit is a unit of information expressed as a choice between two possibilities: a 0 or 1 in binary notation. (Binary is the coding system using the binary digits 0 and 1 to represent a letter, digit or other character in a computer).
This has to do with how many bits the CPU (or a video processor) can handle at a time. That can translate into faster CPUs, the ability to do more things at once, and the detail (or number of colors) on the screen.
16bit is an OLD video game processing capability, like the Nintendo 64 is 64bit, and 16bit also happens to be my favorite. It is the one you most often see game boys running on. Mick is my most common nickname.
Here is an example of 16 bit artwork.
