“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.
