Actually, the first mention of anything like the Internet in fiction occurred in 1946, in Murray Leinster's story, "A Logic Named Joe".

His terms were a little off, but pretty prophetic. "Information tanks", not servers. "Logics", not personal computers.

The story itself is freely available on the web at several sites, including Baen Book's Free Library at Baen.com
