kasutajaaruum

Kasutajaaruum, also known as user space, refers to the portion of a computer's memory that is allocated for user applications and processes. It is distinct from the kernel space, which is reserved for the operating system's core functions and critical processes. The user space is designed to provide a secure and isolated environment for user applications to run without directly interfering with the system's stability or security.

In a typical operating system, the user space is protected from the kernel space by a mechanism called memory protection. This ensures that user applications cannot access or modify the kernel's memory, thereby preventing potential security vulnerabilities and system crashes. The user space is further divided into individual address spaces for each running process, ensuring that one process cannot interfere with another.

The user space is where most user applications, such as web browsers, text editors, and games, execute. It is also where user-level services and libraries operate. The operating system provides an interface, typically through system calls, that allows user applications to interact with the hardware and perform system-level tasks in a controlled and secure manner.

The concept of kasutajaaruum is fundamental to modern operating systems, as it helps maintain system stability, security, and the isolation of processes. By segregating user applications from the core system functions, it minimizes the risk of system crashes and security breaches, making the operating system more robust and reliable.
