voltage range. ADC Converter Circuit Normally analogue-to-digital con-verter (ADC) needs interfacing through a microprocessor to convert analogue data into digital format. This requires hardware and necessary software‚ resulting in increased complexity and hence the total cost. The circuit of A-to-D converter shown here is configured around ADC 0808‚ avoiding the use of a microprocessor. The ADC 0808 is an 8-bit A-to-D converter‚ having data lines D0-D7. It works on the principle of successive approximation

Improvements on common machines Computer- For most of the people‚ computer is a machine used for a calculation or a computation‚ but actually it is much more than that. Precisely Computer is an electronic device for performing arithmetic and logical operation. Or “Computer is a device or a flexible machine to process data and converts it into information.” To know about the complete process that how computer works‚ we will have to come across the various terms such as Data‚ Processing and Information
