- 10. Each user has at least one program executing in memory
- 14. wall Home systems use firewalls to protect home computers from Internet attacks
- 15. A set of software frameworks that provide addition services to application developers such as databases, multimedia, graphics
- 17. scheduling If several jobs ready to run at the same time
- 18. Provides basic computing resources CPU, memory, I/O devices
- 20. servers or storage available over Internet (i.e., storage available for backup use)

Down
- 1. networks Mobile computers interconnect
- 3. Disk Tertiary memory is non- volatile in nature
- 6. program Is loaded at power-up or reboot
- 7. disk Secondary memory is non-volatile in nature
- 9. goals operating system should be easy to design, implement, and maintain, as well as flexible, reliable, error-free, and efficient
- 11. computer Some computers have little or no user interface
- 12. one or more applications available via the Internet (i.e., word processor)

- 19. cloud available via Internet to anyone willing to pay
- 23. Multiprocessing each processor is assigned a specie task.
- 24. If processes don’t fit in memory, moves them in and out to run
- 25. is a communications path
- 27. Multiprocessing each processor performs all tasks
- 29. involves ensuring that all access to system resources is controlled
- 32. memory Allows execution of processes not completely in memory
- 33. goals operating system should be convenient to use, easy to learn, reliable, safe, and fast
