Description: Process allocation refers to the distribution of resources to a process within a computing environment. This concept is fundamental for the efficient management of system resources, as it allows multiple processes to run simultaneously without interfering with each other. In general computing, processes require access to resources such as the CPU, memory, and input/output devices. The allocation of these resources is carried out in two main modes: kernel mode and user mode. In kernel mode, the operating system has full access to all hardware resources, allowing it to manage and allocate resources efficiently and securely. On the other hand, user mode restricts access to certain resources, providing a safer environment for application execution, preventing a malicious or faulty process from affecting the system as a whole. This separation between modes is crucial for the stability and security of the computing environment, allowing processes to run in a controlled and isolated manner. Therefore, process allocation not only refers to the distribution of resources but also to how those resources are managed and protected in different execution contexts.
