Internetworking refers to the process of connecting different networks to form a larger network. It involves using devices and technologies that allow data to flow between different types of networks, ensuring seamless communication across various infrastructures.
The most notable example of internetworking is the Internet itself, which connects countless individual networks worldwide.
Examples of internetworking:
- The internet. It connects a countless number of individual networks through internetworking. The user’s home network, such as Wi-FI, connects to a larger network provided by the internet service provider (ISP), which in turn connects to even larger networks, forming the global internet.
- Business connectivity. Companies with multiple branches often need their separate local area networks (LANs) to communicate with each other. Through internetworking, these LANs can be connected to form a wider network such as a wide area network.
- Data centers and cloud services. Businesses might have multiple data centers in different locations or use cloud services to store their assets. Internetworking allows these disparate resources to work together seamlessly.
- Collaboration and B2B interactions. Businesses can interact with suppliers and clients more efficiently by connecting their respective networks.
- Remote work and learning. Users can connect from various locations to access workplace resources or educational networks.
