By definition, a computer is a machine that can process and store information, like pictures, words, video, numbers, and sounds. Computers complete tasks based on the instructions they are given; for example, if you push a certain key the computer might type the letter “A,” and if you push a different key, it might play a selected song.
Computers are used in all sorts of ways. Computers help professionals to forecast the weather and edit movies. Some factories have computers that help them build their products. Some planes and cars have computers built into them too. At home and in offices, computers let people send emails, write letters, create graphs, store their photos, access the Internet, and play games. – Pretty amazing!
Computers can come in many shapes and sizes depending on what they are used for. In their homes, most people have computers that can fit on their desks or even in their laps, but in many places of work such as science labs, there are sometimes computers that are the size of an entire room!
Think about some things that you use a computer to do, and how your life would be different if you didn't have a computer! Computers didn't become common in homes until recently, so ask some grown-ups you know about how their lives were different before computers!!
