Computer Networks vs. the Internet: Key Differences Explained

📚 What is a Computer Network?

A computer network is a collection of interconnected devices, like computers, servers, and routers, that can communicate and share resources with each other. Think of it like a local neighborhood where everyone can chat and share toys.

• 🔗 Network devices use specific protocols (rules) to communicate, like TCP/IP within a Local Area Network (LAN).
• 🏢 A common example is your home Wi-Fi network, allowing your laptop, phone, and smart TV to connect.
• 💾 The primary goal is resource sharing, such as printers, files, and internet access.

🌐 What is the Internet?

The Internet, on the other hand, is a massive global network of networks. It's the 'network of all networks.' It uses standardized protocols to enable communication between billions of devices worldwide. Think of it as the entire world, where everyone can connect and share information.

• 🌍 The Internet relies on the TCP/IP protocol suite for end-to-end communication.
• 📧 The World Wide Web (WWW), email, and file transfer are just some of the services that operate over the Internet.
• 📡 The primary goal is global communication and information exchange.
