First Come First Serve - processes are moved to the CPU in the order in 1. Application Software - program that help us solve real-world problems which they are arrive in the running state 2. System Software - programs that manage a computer system and interact 19. Shortest Job Next - looks at all processes in the ready state and dispatches with hardware the one with the smallest service time 3. Operating System - system software that manages computer resources and 20. Round Robin - distributes the processing time equitably among all ready provides an interface for system interaction processes 4. Multiprogramming - technique of keeping multiple programs in main memory at the same time, competing for the CPU 5. Memory Management - act of keeping track of how and where programs are loaded in main memory 6. Process Management - act of keeping track of information for active processes 7. CPU Scheduling - act of determining which process in memory is given access to the CPU so that it may execute 8. Process - dynamic representation of a program during execution 9. Timesharing - system in which CPU time is shared among multiple interactive users at the same time 10. Virtual Machine - illusion created by a timesharing system that each user has a dedicated machine 11. Mainframe - large, multiuser computer often associated with early time sharing systems
