Hello, young learners! Welcome back to Primary 3 Basic Science & Technology, Computer Studies. In our previous lesson, we learned about the earliest forms of computers. Today, we’re going to learn about later developments in the history of computers.
Objectives
By the end of this lesson, you should be able to:
- Describe and identify an Abacus.
- Demonstrate counting using an abacus and electronic calculator.
- Define a calculator.
History of Computers – (2)
What is an Abacus?
The Abacus is an early counting tool that uses beads to perform calculations. It’s a mechanical device that was used for centuries before the invention of electronic calculators. The Abacus is still used in some parts of the world today, especially for teaching basic math concepts.
What is a Calculator?
A calculator is an electronic device that is used for performing mathematical calculations. It can be used to add, subtract, multiply, divide, and perform other mathematical operations. Calculators are widely used in schools, offices, and homes.
Evaluation Questions
Now that you’ve learned about the Abacus and the calculator, let’s see if you can answer these questions:
- What is an Abacus used for?
- Can you name an early mechanical counting device?
- How do you use a calculator for addition?
- What are some other ways that the Abacus and the calculator are used? 5. What are the advantages and disadvantages of using an Abacus and a calculator?
Conclusion
In this lesson, we learned about the Abacus and the calculator, two important developments in the history of computers. These devices helped people perform calculations more easily and efficiently.
