Communication systems

Human beings need to communicate to each other. We communicate in many different ways, using different codes (languages, symbols), different means (from drums to satellites) and different speakers and listeners – we can communicate with one person by letter, with a few people in a meeting or a conference, with thousands by radio, or with millions on TV.


The elements of communication in computer networks

The interlocutors. The interlocutors are the people who use the networked computers. They called network users.

The messages. The messages are the files on the network that we can access: written documents, videos, music, drawings, post,… etc.

The means. The means are the computers, which we call workstations.

The codes, called protocols, are the systems that the computers use to understand each other.

Interconnected networks can be in very different places, depending on where we want to connect. To connect several networks, we have to use the same codes on each network. Nowadays it is trendy use the html5 code.
