Document Summary

Token: the smallest meaningful unit of information in a sequence of data for a compiler. Or for networks subdomain: a sequence of bits passed continuously in a fixed order and enabling a node to transmit information. Basic nouns are blue, surrounded in black. Inference rule: 1: a is part of b and b is part of (a kind of) c so a is part of c. Inference rule if a is part of b and b is part of c, a is part of c. A computation acquires, represents, processes, stores, communicates, accesses many kinds of information: eg) calculation. An interpreter creates machine instructions for program lines. A compiler creates machine instructions for the entire program: like translation entire store from chinese english.
