Study Notes
Process Basics
- A process in computer systems is a program in execution, including the current activity, memory, and system resources.
Process Concurrency
- A Trace Graph shows the sequence of process states and transitions over time in the context of process concurrency.
Process Memory
- The private address space in a process is handled by the virtual memory, which is divided into text, data, and stack segments.
CPU and Processes
- A single-CPU computer executes processes one at a time, using time-division multiplexing to allocate the CPU to each process.
Context Switching
- The key function of context switching in a single-CPU computer is to save the current process state and restore the saved state of the newly scheduled process.
