Exposure to Computer Disciplines

Notes 9.5 Keywords

Compiler: A compiler is a computer program (or set of programs) that transforms source code
written in a programming language (the source language) into another computer language (the
target language, often having a binary form known as object code).
Computer programming: Computer programming is the process of designing, writing, testing,
debugging / troubleshooting, and maintaining the source code computer programs.
Debugging: Debugging is a methodical process of finding and reducing the number of bugs,
or defects, in a computer program or a piece of electronic hardware, thus making it behave as
expected.
Hardware interfaces: A hardware interface is described by the mechanical, electrical and logical
signals at the interface and the protocol for sequencing them (sometimes called signaling).
Paradigms: A programming paradigm is a fundamental style of computer programming.
(Compare with a methodology, which is a style of solving specific software engineering problems.)
