Hello, young learners! Welcome back to Primary 4 Basic Science And Technology. In our previous lesson, we learned about Technology And Shelter. Today, we’re going to learn about Technology And Communication.
Objectives
By the end of this lesson, you should be able to: * List 3 different means of communication. * Explain how technology helps us communicate.
Technology And Communication
Technology has significantly impacted how we communicate. It has made it easier and faster to connect with people around the world.
What is Communication?
Communication is the process of sharing information, ideas, and feelings between people. It can be done through speaking, writing, gestures, or technology.
Types of Communication Systems
There are many different types of communication systems, and they all use technology in different ways. Some of the major communication systems include:
- Telephone: The telephone is a device that allows people to talk to each other over long distances. It works by sending voice signals over wires or through wireless networks.
- Radio: A radio broadcasts sound signals, such as music, news, and stories, over the airwaves. People can listen to these signals using a radio receiver.
- Television (TV): Television displays both audio and visual information. It shows programs, movies, and news on a screen, and people can watch and listen to what is being broadcast.
- Computer: Computers can send and receive messages, images, and information through the internet. People can communicate with each other using emails, instant messaging, and video calls.
- Mobile Phones: Mobile phones, also known as cell phones, are portable devices that allow people to make calls, send text messages, and access the internet wirelessly. They are widely used for communication.
Evaluation Questions
Now that you’ve learned about Technology And Communication, let’s see if you can answer these questions:
