TelecommunicationsOn the 10th of March 1876, Alexander Graham Bell "the father of the telephone", relayed the first words by telephone. Nowadays telecommunications systems in general and the telephone in particular, have become indispensable tools for communicating the spoken word in business.
People and organisations are linked nationally and internationally by satellite, radio, undersea cable and land-line which provide telephone, telex, computer and video links. Fibre optic technology and computerised telephone exchanges are leading to even more sophisticated telephone services. Many organisations now operate their own private network systems (PABX) and teleconferencing, whereby a televised meeting of individuals in various different locations can take place, is increasingly popular. In the near future the video-telephone service will be widely available to business and domestic users and will become as common as the car telephone.
