The first three are correct.

Please re-read and re-think the last one. Remember -- "not and external device."

The second answer is wrong!!!

Your answers are partially correct. Here is the correct answer for each question:

1. When a window is displayed in front of another window, it is said to be the active window. So your answer, (c) the active window, is correct.

2. To view a computer's memory properties, you usually need to go to the Control Panel. So the correct answer is (b) Control Panel.

3. To open a program, folder, document, or website, you can use the Run command. So the correct answer is (c) Run.

4. An operating system is not considered an external device. So the correct answer should be (a) operating system.

Here are the corrected answers:
1. (c) the active window
2. (b) Control Panel
3. (c) Run
4. (a) operating system

Great effort though!
