Basic Principles of Logic[edit]
For computer science, it is necessary to understand the basics of logic. Logic is the foundation on which a computer system is built internally. Bits are switched on and off using the binary 1's and 0's. In Boolean Logic, these translate into T (true) and F (false) statements.
