állapotkód

An állapotkód, or status code, is a numerical value used in computing to indicate the result of an operation or the state of a system. These codes are commonly found in various contexts, including network communications, database interactions, and application programming interfaces (APIs). They provide a standardized way for different software components to communicate information about success, failure, or specific conditions.

In web development, HTTP status codes are particularly well-known. These three-digit numbers, such as 200 (OK), 404 (Not Found), and 500 (Internal Server Error), inform clients about the outcome of a request made to a web server. Other systems use different sets of status codes tailored to their specific functionalities. For instance, database systems might use codes to signal successful query execution, constraint violations, or connection issues.

The primary purpose of an állapotkód is to simplify error handling and status reporting. By assigning a unique numerical identifier to each possible outcome, developers can easily check for specific conditions and implement appropriate responses. This promotes code clarity, reduces the need for verbose textual descriptions, and facilitates automated processing of results. Understanding the meaning of different status codes is crucial for debugging and ensuring the reliable operation of software systems.
