Operating systems and applications are made of software. Free Software or open source software is legally licensed and distributed using agreements called licenses that are designed to require no negotiation. The “open” of open source describes the copyright enforced license terms of the software source code. Code is the name for the instructions that make up a program, written in a computer programming language for a particular purpose. Licensed software is usable within the terms of the license.
