4. History of IT There are four main ages of that divide up the history of information technology. Four main ages(Periods) are :- Premechanical Age Mechanical Age Electromechanical Age Electronics Age

5. Premechanical Age (3000 B.C. – 1450A.D.) Petroglyphs -Pictures carved on rocks Writing and Alphabets-communication. Paper and Pens - Input technologies. Books and Libraries: Permanent Storage Devices. The First Numbering Systems. The First Calculators: The Abacus.

6. Mechanical Age (1450 A.D. – 1840 A.D.) The First Information Explosion. The first general purpose “computers” Technologies like Slide rule was discovered. Blaise Pascal invented the Pascaline . Charles Babbage develops difference engine. Difference Engine

7. Electromechanical Age (1840 A.D. -1940 A.D.) The Beginnings of Telecommunication. Voltaic Battery Telegraph was created in early 1800s. Morse Code was created by Samuel Morse.
