Introduction • This section is devoted to the development and use of global communications between individual people and also between groups of people.
The Telephone • The telephone is used as a method of voice communication over distances. Essentially the telephone is made up of a microphone and a speaker connected by wires to other telephones. The spoken voice is converted into electrical impulses that are sent down wires, and converted back into sound by the speaker in the receiving phone. This method of communication does not automatically leave a written copy of a conversation, which in the business world is often important.
Facsimile Machines (Fax) • The fax machine addresses the problem of fast written communication over distance. The machine makes a copy of a paper document, sends it down a telephone line to the receiving fax machine which prints the document out as an exact replica of the original.
The Internet • The Internet functions in the following fashion. There are a number (millions) of host computers or Internet Servers. These are usually 'databases' of information of one sort or another. These server computers are permanently connected to at least one live telephone line or data line eventually connected to the phone system.
Email • This method of communication is similar in its ultimate goal to the fax, in that it is a way of transmitting written documents. In this case, however, the document is not on paper, but has been created on a computer. An email is sent from the source computer to the receiving computer using the telephone lines as the transmission method.
Interactive Whiteboard • It is a complete replacement for most display devices usually found in classrooms, lecture theatres or meeting rooms. It is a whole group teaching and learning resource. Most importantly, it is not a tool designed to be used solely in an ICT room, it is totally cross-curricular.
Video-conferencing • Video-conferencing combines the advantages of direct computer to computer communications, with spoken and video communication.
