Definition

Noun: 1. A system of symbols and rules used to represent instructions or data in a form a computer can process: Computer code is the fundamental set of instructions, written in a specific programming language, that tells a computer what operations to perform. It is the symbolic representation of a program's logic and data. 2. The act or product of writing such instructions: The term can also refer to the activity of programming or the resulting text file containing the instructions.

Usage

• Computer code is written by programmers using programming languages like Python, Java, or C++.
• The code is then translated (compiled or interpreted) into a form the computer's processor can execute directly.
• It is the blueprint for all software, applications, and websites.

Examples

1. As the instructions themselves:

   • The developer reviewed the computer code to find the bug causing the error.
   • This application is built with thousands of lines of computer code.
   • She is learning to write clean and efficient computer code.

2. Referring to the symbolic system:

   • The computer code for the function was a simple "if-else" statement.
   • Machine language is a type of low-level computer code composed of binary numbers.

Advanced Usage

• Source Code: The original, human-readable code written by a programmer. (e.g., )
• Object Code / Machine Code: The low-level code output by a compiler, which is directly executable by the computer's CPU.
• To code (verb): The action of writing computer code. (e.g., )

Variants and Related Words

• Code (noun): A common shortened form of "computer code." (e.g., )
• Programming: The broader process of designing and writing computer code.
• Syntax: The set of rules that defines the structure of valid code in a programming language.
• Algorithm: A step-by-step procedure or formula for solving a problem, which is then implemented in code.

Synonyms

• Program instructions
• Source code (in the context of human-written code)
• Script (often used for code interpreted at runtime, like in JavaScript or Python)

Related Phrases

• To write code: To create computer programs by typing instructions.
• To debug code: To find and fix errors in computer code.
• Codebase: The complete collection of source code used to build a particular application or system.
• Code review: The systematic examination of computer code by one or more developers to improve its quality.

Notes

• "Computer code" is distinct from a cipher or cryptographic code, which is a system for secret communication. In computing, "code" almost always refers to programming instructions unless specified otherwise (e.g., "error correction code").
• The term emphasizes the symbolic and structured nature of programming languages, which serve as an intermediary between human thought and machine operation.

Noun

1. (computer science) the symbolic arrangement of data or instructions in a computer program or the set of such instructions
