How Mobile Phones and Computers Transmit Information - Introduction
Have you ever wondered how you can send a message to a friend or watch a video on your phone or computer? It all happens because of the amazing technology that helps mobile phones and computers transmit information. In this text, we will learn about how these devices send and receive information and the technology that makes it possible.
What is Information Transmission?
Information transmission is the process of sending and receiving data from one place to another.
This can include sending a text message, making a phone call, browsing the internet, or streaming a video. Let's explore how this happens!
How Phones Transmit Information
Mobile phones use radio waves to send and receive information. Here’s how it works when you make a call or send a message.
Making a Phone Call
- Voice to Digital Signal: When you speak into your phone, it converts your voice into a digital signal (a series of ones and zeros).
- Signal Transmission: This digital signal is sent to a nearby phone mast, or tower, using radio waves.
- Network Routing: The mast sends the signal to a network of other masts until it reaches the mast closest to the person you are calling.
- Signal to Voice: The mast sends the digital signal to the recipient’s phone, which converts it back into sound, so the person can hear your voice.
Sending a Text Message
- Typing to Digital Signal: When you type a message on your phone, it is converted into a digital signal.
- Signal Transmission: This signal is sent to the nearest phone mast.
- Network Routing: The message travels through the network to the recipient's mast.
- Message Delivery: The signal is sent to the recipient’s phone, where it is converted back into text.
How Computers Transmit Information
Computers use a combination of wired and wireless technologies to transmit information. Here’s how it works when you connect to the internet or when you send an email.
Connecting to the Internet
- Data Request: When you enter a website address in your browser, your computer sends a request for that website’s data.
- Wired/Wireless Connection: This request travels through a wired connection (like a cable) or a wireless connection (like Wi-Fi) to your internet service provider (ISP).
- ISP to Website Server: The ISP sends the request to the server where the website is hosted.
- Data Transmission: The server sends the website data back to your ISP.
- Data Delivery: The ISP sends the data to your computer, and you see the website on your screen.
Email Communication
- Composing to Digital Signal: When you write an email, your computer converts it into a digital signal.
- Email Server Transmission: The email is sent to your email provider’s server.
- Network Routing: The email server sends the message to the recipient’s email server.
- Email Delivery: The recipient’s email server delivers the message to their inbox.
