ELECTRICITY I. DISCOVER OF ELECTRICITY About 600 B.C.‚ Thales‚ a Greek philosopher and scientist‚ observed that a piece of amber attracted small bits of “paper” or very thin wood shavings after it was rubbed with wool. He had discovered‚ in effect‚ static electricity. William Gilbert‚ an English scientist in the sixteenth century‚ found that many other different materials could be made to act like amber. Whenever these objects were rubbed against each other‚ they were able to attract each other

DCN VIVA QUESTIONS 1. What do you mean by data communication? Ans: It is the exchange of data between two devices via some form of transmission medium such as wire cable. The communicating system must be part of a communication system made up of a combination of hardware and software. The effectiveness of a data communication system depends on three fundamental characteristics: delivery‚ accuracy and timeliness. 2. What is simplex? Ans: It is the mode of communication between two devices in which

Conduction - mainly in solids Convection - mainly in liquids and gases Radiation - any state of matter can absorb/emit infrared radiation. Conduction Vibrations in matter are passed on to transfer heat energy. This is called conduction. Insulator - a material that stops energy being transferred. Solids are good conductors because the particles are closer together and so the particles collide more frequently. Good
