what is information technology, how it affects our daily life, how to protect social media and its benefits?

3. Information Technology
Application of computers to
 Store
 Study
 Retrieve
 Transmit
 Manipulate data, or information,
often in the context of a business or other
enterprise.

4. Which generation of computers
we using ?

7. FIRST GENERATION COMPUTERS
1946-1956
Vacuum tubes (electronic components available)
Vacuum tubes are used for circuitry
Magnetic drums are used for memory.
Input given through punched cards and paper tapes
Output displayed as printouts
No translator from programming language to machine language
Used for scientific research.
