Study Notes
Computer System Components
- A computer system can be divided into four components: hardware, software, data, and people.
Hardware Components
- A modern, multiprocessor computer system includes components such as central processing units (CPUs), memory, and input/output (I/O) devices.
Operating System (OS)
- The primary function of the OS is to manage and allocate system resources to solve computing problems of the users.
- The OS plays a crucial role in a computer system by providing a platform for running application software and managing hardware resources.
CPU and Interrupts
- The CPU provides basic computing resources in a computer system.
- Interrupts play a crucial role in a computer system by allowing the CPU to be interrupted from its normal execution of instructions to attend to a higher-priority task.
- The primary function of interrupts is to handle events that require immediate attention, such as I/O operations or errors.
Mode Transition
- The transition from user mode to kernel mode in a computer system is illustrated by the trap or exception handler.
