A computer system often involves lots of users carrying out tasks. Conventional design is to have multiple users connect to a single server which can allocate resources and communicate with computers on the network.

Napoleon’s Network: A series of mechanical devices that could send signals that were read using a telescope from a distance. Called “tele-graph” meaning far and write.
Electric Telegraph: Developed by the Victorians. Consisted of a network of wires that could send electric signals using Morse code. Rapid adoption. Asynchronous.
