“Mock up” – The possibility of teaching ICT literacy need not be constrained by an absence of computer equipment, since pupils in schools unable to afford such equipment might be guided to construct model computers out of locally available materials. This allows the pupils to gain an understanding of the principles and values associated with computers, networks and peripherals without having real computers in their schools. If teachers were trained accordingly, this type of education will reach even the remotest households. A simile is children making mock-up cars and trucks. Voice over Internet Protocol (VoIP) – Also known as Voice over Internet, IP Telephony or Internet Telephony – refers to telephone services provided over the Internet as the transmission medium. Wide Area Network (WAN) – A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs). Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites. The largest WAN in existence is the Internet. iv
