What happens when you lock your computer?

• A. All programs are closed
• B. You need to sign in again to access running programs
• C. Your system shuts down completely
• D. All data is deleted

Answer: (B)

When you lock your computer, the primary action that occurs is that it requires you to sign in again to regain access to the programs and files that were open at the time of locking. Locking a computer is essentially a way to secure your session without closing any programs or losing unsaved work.

The screen will be obscured, preventing unauthorized users from accessing your applications and data. Upon unlocking, you can continue working right where you left off, with all programs and files intact. This feature is especially useful in environments where you may need to leave your desk but want to ensure that your information remains secure.

In contrast, closing all programs, shutting down the system, or deleting data does not happen with a lock; these actions are unrelated to the locking process and represent different controls for managing a computer’s state or data security.
