1. When your computer is not in use, the screen should go blank after a moment, and you should be required to log in again when you return. T/F
Answer:
Explanation:
This statement is generally true. Having the screen go blank after a moment of inactivity, and requiring a login to return to the computer, is a common security feature known as screen locking. When a computer is locked, it prevents unauthorized access by requiring a password or other form of authentication before the user can regain access to the computer.
This is a useful feature as it helps to prevent sensitive data from being accessed if the computer is left unattended for an extended period of time. The lock time out can be configured in the settings by the administrator and it can depend on the specific operating system you are using.
On Windows, you can set the lock time out by going to the Power & Sleep settings and then selecting Additional power settings. On MacOS, you can set lock time out by going to System Preferences, Security & Privacy, then General and adjust the setting for "require password" after sleep or screen saver begins
It's important to remember that screen locking does not guarantee total security, but it's an important step towards making sure your computer is secure and you should enable this feature if it's available on your operating system.
