23. The sequence of events that occurs between the time that you turn on a computer and the time that it is ready for you to issue commands is referred to as the boot process. 24. Today s Windows operating systems do not require the DOS kernel. 25. One of the primary strengths of Windows is security. 26. One of the reasons Microsoft Windows suffers from the reputation for being the most vulnerable to viruses, worms, and other attacks is because of hackers with anti-establishment sentiments. 27.

To be certain a file can be opened by the recipient, simply save it as an.exe; then anyone can open it. 34. Often file management is represented by a tree metaphor. 35. File management utilities usually retain the files within a folder when that folder is deleted. 36. Viruses can damage files to the point that your computer can't access any data on its hard disk. 37. With remote backups, the speed for backing up and restoring data is independent of the speed of your Internet connection. 38.
