Introduction to Computers OR What is Computer:

Computer Machine:

A Computer is an electronic device that stores, retrieves, and processes information. It helps us to solve wide and varied problems accurately and quickly. The problems may relate to fields such as industry, commerce, engineering, and education. A Computer is an extremely efficient and reliable machine. It has the benefit over the human mind that it does not get bored with repetition and performs a function each time with the same speed and accuracy.

Types of Computer:

 

There are two different types of computers, a desktop and a laptop: 

• Just like using any piece of equipment, when using computers, you have to think about your health and safety. This is why it is significant to make sure your computer is set up correctly.
  
• The monitor or screen is at the accurate height, the top line in line with your line of sight.
  The chair is at the correct height so your feet are on the floor and feel better to work.
  
• The screen is at the correct position and brightness to suit the room you are in.
  The keyboard and mouse are within easy reach to use them easily.
  
• Cables are organized so they don't clutter up the desk or get in the way of your legs under the desk.
  Take regular screen breaks so you are not in the same position for long periods of time.
