Study Notes
- Page map table (PMT) is a table used in virtual memory systems.
- PMT tracks the mapping between virtual pages and physical frames.
- Page swap is the process of moving pages between physical memory and disk storage to manage space.
- Paged memory technique is a memory management method that divides memory into fixed-size pages.
- Paged memory technique minimizes fragmentation and efficiently manages memory.
- Partition memory management is a method of dividing memory into segments or partitions.
- Each memory partition can hold a different process.
- Physical address refers to the actual location in computer memory hardware where data is stored.
- Preemptive scheduling is a CPU scheduling method where a running process can be interrupted and replaced by another before it finishes.
- Process is an instance of a running program that includes its current state and memory information.
- Process control block (PCB) is a data structure the operating system uses.
- PCB stores all information about a process.
- Process management is managing the operating system's execution of processes, including their creation, scheduling, and termination.
- Process states are the various stages a process goes through during its lifecycle, such as new, ready, running, waiting, and terminated.
