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 have a computer, you must take care of it. It is
not difficult to keep your computer healthy and in good working condition. Maintaining a computer
involves three things:
Keeping it physically clean
Protecting it from malware
Backing up your important files
HOW TO KEEP YOUR COMPUTER PHYSICALLY FIT?
The first step in computer safety is to keep your computer physically fit. Dust can potentially destroy
the parts of your computer. By cleaning your computer regularly, you can maintain its performance
and avoid expenses on repairs.
