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
KEEPING 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.
Cleaning the computer means cleaning different parts of the computer system like:
1. Cleaning the Keyboard
Cleaning the keyboard is an important task for
keeping your computer physically fit. Dust and dirt
on the keyboard do not look nice and can prevent
your keyboard from working properly. Particles
such as dust, food, liquid, etc., can get stuck
underneath the keys, which can prevent the keys
from functioning properly. Use a soft cloth to clean
the keys of the keyboard.
