Study Notes
Process Management
- The primary responsibility of the operating system is to manage processes, including creation, scheduling, and termination.
- A program requires execution context, memory space, and access to the CPU for it to run effectively.
- The difference between a program and a process: a program is a static set of instructions, while a process is the dynamic execution of those instructions.
Resources Management
- A process needs CPU time, memory, I/O devices, and files to accomplish its tasks and function properly.
- Upon termination, a process releases all allocated resources, including memory and I/O devices, allowing them to be allocated to other processes.
Memory Management
- Activities regarding memory management include allocation, deallocation, swapping, and managing memory hierarchy.
- Not all activities discussed are integral to memory management, indicating the presence of irrelevant options.
Storage Management
- The primary purpose of the operating system’s storage management is to efficiently manage data storage and retrieval, ensuring optimal utilization of disk space.
- Activities related to file-system management include organizing, accessing, and maintaining metadata, but some options listed may not pertain to these functions.
Mass-Storage Management
- The primary purpose of mass-storage management is to handle and provide reliable access to large amounts of data, ensuring data integrity and efficient access.
- Not every activity is related to mass-storage management; some may fall under other categories or be extraneous to its primary functions.
