Whereas fuzzy logic is an approach to computing based on 'degrees of truth,' modern computing is based on Boolean logic, which is based on the usual 'true or false' (1 or 0) dichotomy. Boolean logic refers to a system of logical thought developed byGeorge Boole(1815-1864) in 1854. He...
A bit (binary digit) is the smallest unit ofdatathat a computer can process and store. A bit is always in one of two physical states, similar to an on/off light switch. The state is represented by a singlebinaryvalue, usually a 0 or 1. However, the state might also be represented ...
In the narrowest possible sci-fi sense, many people intuitively feel that AI refers to robots and computers with human or super-human levels of intelligence and enough personality to act as a character and not just a plot device. In Star Trek, Data is an AI, but the computer is just a...

data types are stored in binary at the machine level, as sets of ones and zeros. That is why character coding is completely necessary in any kind of modern computing, part of the basis for the memory and input/output designs that have become so sophisticated in modern messaging technologies....
What Is an API? An API, or application programming interface, is a set of rules and protocols that allows applications to exchange data, perform actions, and interact in a well-documented way. When a request is made—for a weather update, say—the API processes the request, executes the ...
