Computer

A computer is a machine which manipulates data according to a set of instructions. In the Fallout world, computers range from simple terminals to full blown Artificial Intelligences (or AIs).

Background
One of the major effects of the timeline divergence is that instead of working to develop supercomputers and miniaturized electronics (in the process creating the first semiconductor, the transistor, in 1947), post-World War II humanity in the Fallout universe invested its technological efforts in further harnessing the atom. As a result, computers are far clunkier than the ones in our world and most still use monochromatic, text-based displays. Nonetheless, some are fairly advanced in terms of processing power and intelligence.

Artificial Intelligence
In colloquial parlance, Artificial Intelligence refers to a computer that is "self-aware" - it is capable of not only logical deduction and reasoning, but knows of its own existence, the possibility of its own mortality (and immortality), and possesses creativity, desire, and, in many cases, emotion. Several AIs have appeared in the Fallout games.
