LESSON 1: INTRODUCTION OF COMPUTER & GENERAL INFORMATION
![Page 21: Computer Hardware Servicing Day 1](https://reader034.fdocuments.in/reader034/viewer/2022052217/55cf96d0550346d0338df2d5/html5/thumbnails/21.jpg)
Evolution of Computers
Computer is an electronic machine that accepts the data as input then processes the data and generates the required output as per the processing instructions given to it by the user.

Father of Modern Computer / First Programmer
In 1822, Charles Babbage invented the first modern computer design a steam powered adding machine called “ THE DIFFERENCE ENGINE” and in 1833 he also invented the “ANALYTICAL ENGINE” the analytical engine was a mechanical adding machine that took information from punched cards to solve and print complex mathematical operations.
1842 the first program was written by ADA AUGUSTA LOVELACE for Babbage’s Difference Engine. Thus Ada Lovelace is credited with being the First COMPUTER PROGRAMMER. The programming language ADA is named in her honor.

ESD
![Page 35: Computer Hardware Servicing Day 1](https://reader034.fdocuments.in/reader034/viewer/2022052217/55cf96d0550346d0338df2d5/html5/thumbnails/35.jpg)
What is ESD?
Electrostatic discharge (ESD) is the transfer of an electrostatic charge between two objects. This is a very rapid event that happens when two objects of
different potentials come into direct contact with each other.
One of the main causes of device failures in the semiconductor industry is ESD.
![Page 36: Computer Hardware Servicing Day 1](https://reader034.fdocuments.in/reader034/viewer/2022052217/55cf96d0550346d0338df2d5/html5/thumbnails/36.jpg)
• Keep all components in antistatic bags until you are ready to install them.
• Use grounded mats on workbenches.• Use grounded floor mats in work areas.• Use antistatic straps when working on
components.
