1 STUDY GUIDE CHAPTER 4 True/False Indicate whether the statement is true or false. 1. A(n) desktop operating system is designed for a desktop or notebook personal computer. 2. A(n) mirrored user interface provides a way to select menu options and manipulate graphical objects displayed on the screen using a mouse or gesture. 3. Mac OS X is a good platform for virtual host technologies that allows you to use one computer to simulate the hardware and software of another. 4. UNIX is rather unique because it is distributed along with its source code under the terms of a GPL (General Public License). 5. Windows Mobile OS is an open source operating system designed for mobile devices and is based on the Linux kernel. 6. DOS and Windows 3.1 limited file names to fifteen characters. 7. A file type is an optional file identifier that is separated from the main file name by a period. 8. The section of data at the beginning of a file that contains information about a file is the file format. 9. When formatting a disk, the disk is divided into tracks. 10. When formatting a disk, tracks are divided into sectors. 11. Tracks and sectors are numbered to provide addresses for each data storage bin. 12. Online backup services are also referred to as remote or managed backup services. 13. A program called AutoBackup supplied with Mac OS X is a good example of synchronization software. 14. A(n) operating-system disk is a removable storage medium containing the operating system files needed to boot your computer without accessing the hard disk. 15. A restore point is a snapshot of your computer settings. 16. An operating system acts as the master controller of all of the activities that take place within a computer system. 17. When using Windows, the Shift+Alt+Del key sequence opens the Task Manager, which shows a list of processes being executed by the microprocessor. 18. One difference between Microsoft Windows and Mac OS is that only Windows features multiple rectangular work areas (called windows) to reflect multitasking capabilities. 19. In Windows 7 and Mac OS X you can use spaces in file names. 20. During a typical computing session, your computer might run an average of 50 processes. 21. A combo button allows you to select one item from several options. 22. During the boot process, the operating system is totally loaded into the kernel.

2 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. In a dual boot system, to change operating systems, you have to reboot. 28. A General Purpose License, or GPL, allows anyone to make copies for their own use or to give or sell to others. 29. The D drive must refer to a CD or DVD drive. 30. When you use Windows, Mac OS, or a Linux graphical file manager, each subdirectory is depicted as a folder. 31. When creating a file, you must keep up with the size of the file manually. 32. A file extension is always the same as a file format. 33. 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. Some systems streamline the backup process by restoring a computer s operating system, device drivers, settings, and data in a single step--a process called restore pointing. Multiple Choice Identify the choice that best completes the statement or answers the question. 39. Suppose that you're looking in a folder and see lots of files with.tmp,.dll,.com, and.hlp extensions. You should. a. delete all those files because they are c. hide the file extensions so that the unneeded files taking up disk space programs they contain will not be b. leave the files alone because they are probably required for the correct operation of an application program executed d. rename all the files so that the extensions match

3 40. Graphical user interfaces depend on menus that offer users a list of valid commands for controlling an application. There can be many options associated with a command, however.
