Document Summary
1. 2: hardware and software: computers process data under the control of sequences of instructions called computer programs, converting languages into 0s and 1s. 1. 3 data hierarchy: characters can be made of a few bits, bit - smallest data item in the computer representing the value 0 or the value 1, short for binary. Fields - composed of characters or bytes, a group of characters that convey meaning. File - a group of related records, can be viewed as a sequence of bytes: database - collection of data organized for easy access and manipulation, big data - applications that deal with large amounts of data. Interpreter - reads line by line, executes line by line, however is a slow process, but allows for correction of mistakes, between you and the computer, inter meaning between. 1. 6 c standard library: c programs are made of pieces called function, existing functions can be found in the c standard library.
