The Internet is a global system of interconnected computer networks that use the Internet Protocol Suite (TCP/IP) to communicate. It is a vast network of networks, where different types of networks (such as LANs and WANs) are connected to allow data and resources to be shared across the globe. The Internet enables services such as email, websites, file sharing, and online communication.
Relationship between Internet and WAN:
The Internet is a type of Wide Area Network (WAN), but on a much larger scale. Here's how they relate:
- WAN is any network that spans a large geographic area, such as a corporation's network that connects offices across different regions or countries. WANs typically rely on leased telecommunication lines or satellite connections.
- The Internet can be seen as the largest WAN, connecting smaller networks (like LANs and MANs) around the world. It provides the backbone for communication across different WANs, allowing devices and networks to interact regardless of their physical location.
In summary, the Internet is a form of WAN that links many smaller networks, allowing users across the world to communicate and share resources.
