computer code

A programmer writes computer code on a laptop.

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.
