Study Notes
Operating System Functions
- Acts as an intermediary connecting users to computer hardware, facilitating user interactions and command executions.
- Provides a user interface, allowing users to issue commands and receive output from the hardware.
Basic Computing Resources
- The computer hardware itself provides essential computing resources such as the CPU, memory, and storage devices.
- These resources are utilized by the operating system to enable software applications to run effectively.
Efficient Hardware Utilization
- The main goal of an Operating System is to optimize the use of hardware resources, ensuring maximum efficiency and performance.
- It works to minimize idle times and ensure that all components are actively engaged in processing tasks.
Resource Management Perspective
- The operating system's resource management perspective involves overseeing the allocation of system resources to various programs.
- It ensures fair distribution, prioritization, and proper execution of processes to avoid conflicts and maximize performance.
Control Program Role
- The control program perspective is focused on supervising and coordinating all tasks within the system.
- It handles system commands, manages resource allocation, and maintains overall system stability and reliability.
