Computer Networks



Wide Area Networks (WANs) - connect hardware devices in locations at great distances from each other.

Store-and-forward packet switching protocol means information goes from source to destination as a packet of information; the number of packets (of fixed size) needed depends on the size of the message. At destination, packets are reassembled to recreate the original message.


Special devices called routers in WANs use complex algorithms to determine shortest path between nodes for packet transmission.
