Computer safety refers to the protection of computer-based resources against unauthorised use or
physical damage.
You know that computers are expensive, so if you own a computer, it’s important to take proper care
of it. Keeping a computer in good working condition is not difficult. Maintaining a computer involves
three key aspects:
Keeping it physically clean
Protecting it from malware
Backing up your important files
HOW TO KEEP YOUR COMPUTER PHYSICALLY FIT?
The first step in ensuring your computer's safety is to keep it physically well-maintained. Dust can
potentially damage the components of your computer. By cleaning your computer regularly, you can
maintain its performance and avoid costly repairs.
