In the 1960s, researchers in the US were trying to build a network that could keep working even if part of it went down.

Later, a project called ARPANET (2) .......... the first real test of these ideas, linking a few universities. At first, it was mainly scientists who used it, and they were more interested in sending messages than browsing websites.\n\nThe big change came when TCP/IP became the standard way for computers to “talk” to each other.
