Types of Code
Type of Code | Definition | Characteristics | Applications |
---|---|---|---|
Source Code | The original code written by developers using a programming language. | Readable by humans, written in high-level programming languages, requires translation into machine code. | Primary form of code created by developers. Used for collaboration, version control, and documentation. |
Machine Code | The binary representation of instructions that a computer’s CPU can directly execute. | Comprises binary digits (0s and 1s), directly understandable by the computer’s hardware, generated through compilation or interpretation of source code. | Executed by the CPU to perform tasks specified in the source code. The result of compiling or interpreting high-level languages. |
Bytecode | An intermediate code that is a low-level representation of source code. | Intermediate between source code and machine code, platform-independent, typically generated by languages like Java or C#. | Used in environments with virtual machines (e.g., Java Virtual Machine). Allows for portability across different systems. |
Compiled Code | The result of translating the entire source code into machine code before execution. | Source code is translated entirely before execution, faster execution compared to interpretation, generates an executable file. | Common in languages like C, C++, and Rust. Suitable for performance-critical applications. |
Interpreted Code | Executed line by line, without the need for prior compilation. | Source code is executed line by line, slower execution compared to compilation, no separate executable file is generated. | Common in scripting languages like Python, JavaScript, and Ruby. Allows for rapid development and easy debugging. |
Scripting Code | Code written in scripting languages, often interpreted, used for automating tasks or adding functionality. | Typically interpreted, emphasizes ease of use and readability, often used for automation and customization. | Writing automation scripts, adding functionality to web pages (JavaScript). |
Assembly Code | A low-level programming language closely corresponding to machine code, specific to a CPU architecture. | Closer to machine code, uses mnemonic instructions, requires translation by an assembler. | Programming for specific hardware platforms, embedded systems, and system programming. |
Front-End Code | Code executed by a user’s browser, including HTML, CSS, and JavaScript. | Runs in the user’s browser, shapes the visual and interactive elements of a website, executed on the client side. | Building user interfaces for websites, enhancing user experience through interactivity. |
Back-End Cod | Server-side code that powers the server, manages data, logic, and communication between client and server. | Executes on the server, manages databases, business logic, and server-side operations, responds to client requests. | Handling data processing and storage, managing user authentication and authorization. |
Database Code | Code written for database management systems (DBMS) to define, manipulate, and query databases. | SQL (Structured Query Language) is a common language for database code, manages database structure, data, and queries. | Defining tables and relationships in a database, performing queries to retrieve or modify data. |
What is a Code in Programming?
In programming, “code” refers to a set of instructions or commands written in a programming language that a computer can understand and execute. In this article, we will learn about the basics of Code, types of Codes and difference between Code, Program, Script, etc.
