EVOLUTION OF COMPUTERS.   INTRODUCTION, DEFINITION

  1.  INTRODUCTION   OF COMPUTER SYSTEM;

The term computer is derived from the word “compute” to compute means to calculate. Hence, people usually consider a computer to be a calculating device that can perform arithmetic operation at high-speed. And term computer can logically be applied to any calculating device.

A computer can be defined as an electronic device that operates on data, analyzes it and then applies a predefined set of instruction to it to produce some kind of output. A computer is often referred to as a data processor because it can store, process, and retrieve data whenever desired. The name data processor is more inclusive because modern computer not only compute in the usual sense but also perform other function with data flows to and from them.

For example, data processor may gather data from various incoming sources, merge them all, sort them in desired format. Notice that none of these operation involves arithmetic computations in the usual sense but a computer is the most suitable device for performing them.

In the case of computers data is transferred from one part to another through electronic circuits such as switches etc.

A computer is an electronic device that enters the data as input, processes the data store to it as per user’s requirement and provide us the required instructions as output as with high-speed and accuracy.

Computer can perform mathematical and non-mathematical operations. The input is entered into the computer through an input device like keyboard and output is received through output device like printer etc.

The full form of computer is:

       C: – commonly

       O: – operated

       M: – machine

       P: – particularly

       U: – used for

       T: – trade

       E: – education

       R: – research

Computer have made a rapid process. Now almost every person is familiar with the word computer. Earlier, the use of computer was limited only to technical people such an engineers and research scientists. Then started the computer revolution and with lowering of prices, lesser space consumption, lesser learning skills required, easy plug and play and multimedia tools available. These quantities made them a part of our daily life.

A Principle of Witricity

A Principle of Witricity

Electrical resonance: Electrical resonance happens in an electrical circuit at a selected resonance frequency once the electric resistance between the input and output of the circuit is at a minimum (or once the transfer f maximum). Typically this happens once the electric resistance between the input and output of the circuit is sort of zero and once the transfer operates is near one. Resonance of a circuit involving electrical devices and inductances happens as a result of the collapsing magnetic flux of the inductor generates an electrical current in its windings that charges the capacitor, and so the discharging electrical device provides an electrical current that builds the magnetic flux within the inductance, and also the method is perennial frequently
