How Did Computers Change History?
Computers have changed a lot since they were first invented. A long time ago, computers were big machines that could only do simple tasks, like solving math problems. Now, computers are small enough to fit in our hands and can do so much more!
Today, computers help us in many parts of our lives:
- At school: We use computers to look up information, write stories, and practice math.
- For work: Grown-ups use computers to do their jobs faster and connect with people from all over the world.
- For fun: Computers let us play games, watch videos, and listen to music.
- To stay in touch: With computers, we can send messages, make video calls, and talk to friends and family anytime, anywhere.
Computers have become so important in our world that we use them almost every day! Let’s explore how computers started, how they grew over time, and how they’ve made our lives better and different.

What is a Computer?
A computer is a machine that:
- Helps us solve problems
- Stores and remembers information
- Follows instructions we give it
- Connects us to other people
Computers make things easier and faster for us!
The First Computers
Long ago, there were no computers like the ones we have today. The first “computers” were actually people who did math by hand! Then, inventors began building machines to help with big math problems.
The early computers:
- Were huge and took up whole rooms
- Were very slow compared to today’s computers
- Could only do simple tasks like math
Fun Fact: One of the first big machines, called the ENIAC, was so large it needed a whole room to fit inside!
The Timeline of Computers
Let’s look at how computers have changed over the years.
1940s: The Very First Computers
- Big, heavy machines
- Could only do math
- Used by the government for important work
1950s: Smaller and Faster
- Started being used in schools and businesses
- Still very big, but faster than before
1970s: Personal Computers
- Became small enough to fit on a desk
- People could buy them for home use
- Companies like Apple and IBM made popular computers
1990s: Internet and Laptops
