A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data

Charles Babbage, an English mechanical engineer, originated the concept of a programmable computer. He is considered as the "father of the computer", he conceptualized and invented the first mechanical computer in the early 19th century

The ENIAC (Electronic Numerical Integrator and Computer) was the first electronic programmable computer built in the US.

An Introduction

 Electricity is generated from the motion of tiny charged atomic particles called electrons and protons!  Protons = +  Electrons = -

 Thermal  Geothermal  Nuclear  Hydroelectric  Solar  Wind

 Energy from one of the sources is converted by machines at the power plant to Electricity and then put onto the Electric Power Grid  Electric Power Grid Power Plants Transmission Lines Substations Power Lines Transformers Electrical Wiring and Circuit Box

 How would you prepare your lunch?  How would you wash clothes?  When would you go to bed?  Think about all the luxuries the discovery of Electricity has brought us! No Television No Radio No Lights
