Hi, students! Welcome back to Primary 3 Basic Science & Technology, Computer Studies. In our previous lesson, we learned about No previous lesson found.. Today, we’re going to learn about the HISTORY OF COMPUTER – (1).
Objectives
By the end of this lesson, you should be able to: * Define counting devices * Demonstrate counting using objects * Explain the concept of early computing * List 5 devices/objects used in the early days of computers.
HISTORY OF COMPUTER
Counting is the foundation of early computers.
Counting devices are tools that help us count and keep track of numbers. These can be everyday items like our fingers or special objects like pebbles, sticks, or shells. They make it easier for us to do math and keep count of things.
In the early days of computing, we used our fingers, toes, pebbles, stones, sticks, cowries, and seeds to count. These early counting methods led to the development of computers.
The Concept of Early Computing
In the days of early counting devices, computing primarily meant performing mathematical operations manually or with the help of simple tools like pebbles, sticks, and fingers.
Early Counting Devices
Some of the early counting devices include:
- Fingers and Toes: Our fingers and toes were the first counting tools. People used them to count objects and keep track of numbers.
- Pebbles, Stones, and Sticks: These objects were used to represent numbers. People would move them around to perform calculations.
- Cowries and Seeds: These were often used as currency in some cultures. They were also used for counting and keeping track of possessions.
Evaluation Questions
Now that you’ve learned about the history of computers, let’s see if you can answer these questions:
- What is the topic of our lesson today?
- Name two objects people used for counting in the past.
- Explain the importance of counting in computing.
- Demonstrate counting using pebbles or stones.
- List five devices/objects used in the early days of computers.
Conclusion
Today, we learned about the history of computers and how counting played a crucial role in their development. We explored various early counting devices and understood how they contributed to the evolution of computing.
