† F† 1. An operating system must reside inside a computer or mobile device; that is, it cannot run from a USB flash drive or other external drives.

† F† 2. The kernel is nonresident, which means it remains in memory while the computer or mobile device is running.

† T† 3. A user interface controls how you enter data and instructions and how information is displayed on the screen.

† F† 4. Most users today work with a command-line interface.

††T† 5. Most operating systems today are multitasking.

† T† 6. The area of the hard drive used for virtual memory is called a swap file.

† T† 7. Each device connected to a computer requires its own specific driver.

† F †8. Hackers often look for ways to break into a computer or device using flaws in the operating system.

† T† 9. Many of the first operating systems were device dependent and proprietary.

† F† 10. An upward compatible application means it can recognize and work with applications written for an earlier version of the operating system.

† F† 11. Linux is proprietary software.

† T† 12. Operating systems that function as both desktop and server operating systems sometimes are called multipurpose operating systems.

Problem Solving:

1.       My first step would be to check to see if caps lock was on then I would type my password out slowly to make sure it was spelled correctly.

2.       Your computer may have had some issues so it automatically backed up to a time when the issues wasnít there.

3.       The first thing I would do would be to check to see if there were updates to the programs if not I would see if I could revert to an earlier operating system.

4.       Sometime when you create an account on a computer you donít give that account admin privileges.

5.       Your computer may not be connected to the services that tell if there is an update or not.
