As technology continues to evolve, hackers are becoming more adept at breaking into older systems and software. By updating operating systems and software in a timely manner, hacker attacks and exploits of vulnerabilities can be effectively avoided.

3. Back up important data

When using computers, we often store a variety of important files and data. Therefore, backing up your data is also very important when it comes to keeping your computer safe.

The purpose of backing up data is to ensure the security and integrity of the data in the event of computer failure or data loss.

4. Password settings

When using computers, we often need to set various passwords. Therefore, password setting is very important. Passwords need to be strong enough to not be easily cracked and can contain a variety of combinations of letters, numbers, and symbols.
