Käyttäjäistunnon

Käyttäjäistunto refers to a user session in computing. It represents a period of interaction between a user and a computer system or application. When a user logs into a system, accesses a website, or starts using a program, a session is initiated. This session is a temporary state that keeps track of the user's activities, preferences, and data within that specific interaction.

During a user session, the system remembers information about the user. This can include login credentials, shopping cart contents on an e-commerce site, or the current progress in a game. Sessions are typically managed using session identifiers, which are unique codes assigned to each user. These identifiers allow the system to distinguish between different users and maintain their individual states.

Sessions have a defined lifespan. They can end when the user explicitly logs out, closes the application or browser, or after a period of inactivity, known as session timeout. This timeout mechanism helps to improve security by automatically terminating inactive sessions, preventing unauthorized access. Understanding user sessions is crucial for web developers, system administrators, and anyone involved in designing and managing user experiences in digital environments.
