V. Read the text: Intelligent homes

A. Domotics, from the Larne word domus plus robotics, also known as automation, involves the use of information technology applied to domestic appliances in order to creare intelligent systems inside the house.

Basic intelligent devices, traditional devices with an embedded processor, have been with us for a while, e.g. microwave ovens and washing machines with computerized controls.

Intelligent homes are a wider concept; all the systems and devices are connected in a LAN, local area network, where they communicate with each other and are controlled by a central computer sometimes installed in one of the machines.

B. Control devices and networking.

Intelligent homes are controlled with different types of interfaces, devices that facilitate communication between the user and the system: physical swishes, touch screens , or IR (infrared ) remote controls, computers either at home or at a distance, telephony.

The different elements perform one of these two functions: they are their command initiators, e.g. a brightness sensor that is programmed to send an instruction when it gets dark, or command receivers , e.g. a light that turns on when it receives an instruction sent by the sensor.

Household appliances, sound and video system, optical and thermal sensor, etc, can be linked with wired and wireless systems.Wired LANs use different types of cables and also electrical wiring.

WLANs, wireless networks, use radio-frequency systems: Bluetooth, a short-range radio system used to communicate between portable devices(laptops, PDAs, mobile phones, etc), is now frequently used to design PANs (personal area networks) inside the home.
