The term “code” can have multiple meanings depending on the context. In programming, code is writing programming statements, also known as source code, to create a computer program.
Information Transformation and Communication
In communication and information processing, code refers to a set of rules that transform information into a different form, often more concisely or secretively.
This process involves encoding, which converts information into symbols for communication or storage. The reverse process, decoding, converts code symbols back into a recognizable form.
This substitution is employed to provide secrecy or confidentiality.
