Whether it’s your phone using Wi-Fi or offices sharing printers, computer networks make it all possible. In this beginner-friendly episode, we’ll explain:
- What a computer network is
- Why networks are important
- Real-life examples you already use
Let’s break it down simply.
What is a Computer Network?
A computer network is a group of two or more connected devices that can communicate, share data, and resources with each other.
Think of it like:
A digital road system where computers, phones, printers, and servers send and receive information.
Why Are Computer Networks Important?
Networks allow us to:
- Access the internet (emails, websites, cloud apps)
- Share files and documents easily
- Use shared devices like printers or servers
- Collaborate in real-time (chat, video calls, remote access)
Without networks, every device would be isolated and unable to talk to others.
Real-Life Examples of Computer Networks
- Home Wi-Fi
- Your phone, laptop, and smart TV all connect to one router.
- You can stream Netflix on one device while downloading files on another.
This is a small Local Area Network (LAN).
2. Office LAN (Local Area Network)
- Employees share files, printers, and internal applications.
- Computers are connected using Ethernet cables or Wi-Fi.
LANs are fast, secure, and used in schools, offices, and labs.
3. The Internet (A Global Network)
- Billions of devices worldwide are connected through servers and routers.
- Websites, apps, video calls, and online gaming all rely on this massive network.
The internet is technically a network of networks — the largest in the world.

Did You Know?
The first computer network was ARPANET, created in the 1960s by the U.S. government — and it eventually evolved into today’s internet.
