FACTOID # 142: Americans consume the sixth-most spirits, the eighth-most beer and the 18th-most wine. They’re also likely to view heavy drinkers as undesirable neighbors.

Encyclopedia > Dataflow architecture

Dataflow architecture is a computer architecture that directly contrasts the traditional von Neuman or control flow architecture. Dataflow architectures do not have a program counter or (at least conceptually) main memory and the executability and execution of instruction is determined based on availability of input arguments to the instructions. No commercially successful computer hardware has used a dataflow architecture. In computer science, computer architecture is the conceptual design and fundamental operational structure of a computer system. ... In computer science and in computer programming, statements in pseudocode or in a program are normally obeyed (or executed) one after the other in the order in which they are written (sequential flow of control). ... The program counter (also called the instruction pointer in some computers) is a register in a computer processor which indicates where the computer is in its instruction sequence. ... Primary storage is a category of computer storage, often called main memory. ...
