Code

Understanding Code

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.

Cryptographic Code

In the field of cryptography, code has specific technical meanings. It involves substituting one word, phrase, number, or symbol with another to obscure the original purpose.

This substitution is employed to provide secrecy or confidentiality.
