SIMPLE PAST

The Invention of Computers

Computers have come a long way since their invention. They were not always like the ones we have today. Let's take a look at how computers were in the past.

The first computers were big machines. They were not like the small laptops we use now. They were huge and heavy. In the past, computers were not for everyday people. They were mostly used by scientists and engineers.

The first computer was called the "ENIAC." It was built in the 1940s. The ENIAC was as big as a room! It had many wires and switches. It was not easy to use.

Computers in the past were not fast. They were slower than the computers we have today. People had to be patient when using them.

In the past, computers did not have screens like we do now. They used punch cards to give them instructions. People had to punch holes in cards to tell the computer what to do.

As time went by, computers got smaller and faster. They became more useful for everyday tasks. Now, we can carry a computer in our pockets. We use them for work, school, and entertainment.

The invention of computers changed the world. They help us do many things faster and better. Computers have a long and interesting history, and they continue to evolve.
