Assignment 4 1. The system displays the following message when you attempt to log in with an incorrect username or an incorrect password: Login incorrect a. This message does not indicate whether your username, your password, or both are invalid. Why does it not reveal this information? By not revealing if it was either the username or the password that was wrong, it discourages people to try to guess the one that was wrong, as they don’t know which one it is. It’s less likely for unauthorized users to access the system. b. Why does the system wait for a couple of seconds to respond after you supply an incorrect username or password? It’s to keep users from running a script and keep guessing the account login details. 3. Is fido an acceptable password? Give several reasons why or why not. fido is not a good password. An acceptable password shouldn’t be only letters. It should have non alphanumeric characters, numbers, and lower and uppercase letters. It should also be at least 8 characters. fido is too short. 5. What is a workspace? What is the relationship between a workspace and the desktop? A workspace is a screen that holds windows of one or more applications and a desktop is a collection of all the workspaces. 7. What is an Application menu? What does it allow you to do? An application menu is a menu that allows you to set preferences and get you help with the application. 9. Describe three ways to

a. Change the size of a window. ­You can double­click the titlebar (which appears at the top of most windows and controls the window is is attached to) to maximize and restore a window. ­You can also use the windows operations menu which lets you resize the window. ­Another way to resize a window is by positioning the mouse pointer over an edge of the window until the pointer turns into an arrow pointing to a line. Then you can click and drag the side of a window. If you position the mouse pointer over a corner of a window, you can resize both the height and the width of the window at the same time. b. Delete a window. You can close a window by clicking the close button (X) on the titlebar. You can also use the Windows Operations menu to close a window. 11. How would you set the system time manually? You can set the Date & Time by using the Settings Window. Date & Time allows you to specify a date format, a time zone and turn NTP on or off. To set the system time manually, set NTP off. To specify a time zone, click a city in the local time zone, then GNOME displays the name of the city in the spin box labeled City. You can also use the spin boxes labeled Region and City to specify a city.
