The Internet is a massive network of routers that connect countless computer networks around the world. It isn’t one single network; it’s a “network of networks.” Each organization may run its own local network, and those networks link together through gateways and routers that forward data from one network to another. Data travels as small packets, with routers choosing the best path to move each packet toward its destination, sometimes changing routes along the way. This system uses standard protocols like TCP/IP so diverse networks can communicate. It’s not a private database and not confined to a single local network.
