How does a computer perform a graceful shutdown?

When shutting down a computer, the operating system starts a sequence that safely closes all active programs, saves user data, and then powers off the system. This process is known as a graceful shutdown. It helps prevent data loss and ensures the computer terminates all processes properly before turning off.

Why is it essential to shut down a computer correctly?

Shutting down a computer correctly ensures that all running processes and applications are closed safely. Improper shutdowns, like sudden power loss or forced shutdowns, can lead to data corruption, file system errors, and hardware damage. Regularly shutting down the computer correctly helps maintain system stability and longevity.

When should I perform a restart instead of a shutdown?

Restarting a computer is advisable when software updates or system changes require a full system reboot to apply changes effectively. It also helps in resolving certain performance issues and memory leaks, as restarting clears the RAM and refreshes the system.
