Document Summary

Signals: analog-continuous: values can be found in between each signal, digital-discrete: on or off. Nothing in between: perfect reproduction, can be fully recovered, boolean logic: base-2 numeric system. Data: quantities, characters, or symbols on which operations are performed by a computer and are transmitted in the form of electrical signals. Information is the processed data that has meaning. Abstraction: the intuitive simplification of a concept, trash can icon for delete. Algorithms: precise instructions that solve a specific problem, best possible way to do something effectively and efficiently.
