There are several terminologies that relate the processor to the operating system. Here are some of the key terms:
1. CPU (Central Processing Unit): The CPU is the primary component of a computer that executes instructions and performs calculations. It is responsible for carrying out the instructions provided by the operating system.
2. Process: In the context of an operating system, a process refers to an instance of a program that is being executed by the CPU. It includes the program code, data, and resources required to execute the program.
3. Multitasking: Multitasking is the ability of an operating system to execute multiple processes concurrently. The CPU switches between different processes rapidly, giving the illusion of simultaneous execution.
4. Scheduling: CPU scheduling is the process by which the operating system determines the order in which processes are executed on the CPU. It involves allocating CPU time to different processes based on priority, fairness, and other factors.
5. Context Switching: Context switching is the process of saving the current state of a process and loading the saved state of another process. It occurs when the operating system switches the CPU from one process to another.
6. Interrupts: Interrupts are signals sent by hardware devices or software to the CPU to gain its attention. They can be used to handle events that require immediate processing, such as keyboard input or hardware errors.
7. Kernel: The kernel is the core component of an operating system that directly interacts with the hardware. It manages resources, provides services to applications, and controls the execution of processes on the CPU.
8. System Calls: System calls are functions provided by the operating system that allow applications to request services from the kernel. They provide an interface for applications to interact with the underlying hardware and perform privileged operations.
9. Deadlock: Deadlock is a situation where two or more processes are unable to proceed because each is waiting for a resource held by another process. It can occur when the operating system fails to manage resources properly, leading to a system freeze.
10. CPU Affinity: CPU affinity refers to the assignment of specific processes or threads to particular CPU cores. It can improve performance by reducing cache misses and improving thread synchronization.
These terminologies help describe the relationship and interaction between the processor and the operating system, highlighting how the operating system manages and utilizes the CPU's resources to execute processes efficiently.
