Email — Client/Server Model
Electronic mail works on the client/server principle. A client program enables the user to read, reply, forward, compose and send messages, while the server stores all messages on the user’s mail account. Email is the cheapest and most convenient form of communication compared to telephone or fax. Messages are transmitted through Intranet, Internet and Extranet. Common e-mail client programmes include Qualcomm Eudora, pine, elm and Lotus cc:Mail. Note: WhatsApp is a social media app — it does NOT provide an email feature.
