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.
Test your knowledge of program level representation, processes, and exceptional control flow in computer systems and programming with this quiz. Topics covered include logical control flow, exclusive CPU access, private address space, and more.
