Study Notes
- A real-time system is a computing system that processes data and responds to inputs in a specific, and often very short, time frame.
- Response time is the time taken from the submission of a request to the start of the system's response.
- Round-robin is a CPU scheduling algorithm where each process is assigned a fixed time slice in a rotating order.
- Shortest job next (SJN) is a CPU scheduling algorithm that selects the process with the shortest expected execution time next.
- Single contiguous memory management is a memory management method where all processes are loaded into a single contiguous block of memory.
- System software is designed to provide a platform for other software, including operating systems and utility programs.
- Thrashing is a condition where excessive paging operations occur, leading to reduced system performance.
- Time slice is a fixed amount of CPU time allocated to each process in a round-robin scheduling algorithm.
- Timesharing is a method where multiple users can access a computer system concurrently by sharing time slices of the CPU.
- Turnaround time is the total time taken from the submission of a process to its completion.
