A long time ago, people counted with only their fingers and toes. Later on, they learned how to count with sticks and stones. In 5000 BC, a counting device called abacus was invented to make counting easier.
Our world today is very different from what it was many years ago. Many of the changes we now have are because of computers.
One of the greatest innovations brought about by the computer technology is the internet.
