The idea of a computer network intended to allow general communication between users of various computers has developed through a large number of stages.
Prior to the widespread inter-networking that led to the Internet, most communication networks were limited by their nature to only allow communications between the stations on the network.

The country consists of a large mainland at the southern end of the Balkans; the Peloponnesus peninsula (separated from the mainland by the canal of the Isthmus of Corinth); and numerous islands (around 3,000), including Crete, Rhodes, Euboea and the Dodecanese and Cycladic groups of the Aegean Sea as well as the Ionian sea islands.
Greece also has some Roman Catholics, mainly in the city of Patras and the Cyclades islands of Syros, Paros and Naxos; some Protestants and some Jews, mainly in Thessaloniki (which was once a major Jewish city until the Holocaust).
