állapotmentesek

Állapotmentesek, a Hungarian term, translates to "stateless" in English and is primarily used in the context of computer science and networking. It refers to systems or components that do not store any client-specific data between requests. This means that each request is treated as an independent transaction, and the server or application does not need to remember any previous interactions with the client.

In stateless architectures, all the necessary information to process a request must be included within the request itself. This contrasts with stateful systems, where the server maintains a session or state for each client, allowing for more complex interactions over time. Statelessness simplifies server design and management, as there is no need to handle session data, which can be prone to issues like synchronization or data loss.

A common example of a stateless protocol is HTTP, the foundation of the World Wide Web. Each HTTP request from a browser to a web server is independent. While technologies like cookies and sessions can be used to simulate statefulness on top of HTTP, the protocol itself is designed to be stateless. This design choice has been crucial for the scalability and resilience of the internet, enabling easy load balancing and recovery from server failures. Stateless systems are generally easier to scale horizontally by adding more identical servers, as any server can handle any incoming request without needing to access shared session data.
