St : Sir, Good Morning Sir, Hope you remember me, I am Kannan.

Te : Come on, Kanna... How can I forget you? Two years back you had attended Commerce Tuitions? How is your life now?

St : I am fine sir? How about you sir?

Te : I am fine Kanna. What can I do for you now?

St : Sir, Now I gat an interest to know many things about computers, sir. That’s why I have visited you sir?

Te : Long back you enquired me about learning Computers, but you didn’t turned up for a long time. At least now you have come back, "Better Late than Never."

St : Sir, As I was seeking job in some other discipline, I was not showing much interest in learning computers. But now whaterver discipline I enter it involves computer proficiency to some or other extent. That’s why now I have decided to explore more about computers, sir.

Te : In the present day scenario, whatever line of profession you choose, computer knowledge will certainly be an inseperable part in that profession, Kanna.

St : Sir, before learning computers I would like to know some basic infomations about computers, sir. It will be very useful for me if you could explain it to me in a very simple manner.

Because, Whenever I attend an interview it will be useful for me to answere the basic question put forward agaist me.

Moreover, when computer literates discuss some preliminary things about computers I shall be in a position to understand whatever they speak.

Te : O yes Kanna, Its my pleasure. You ask your doubts as questions, so that I shall answer you. I hope this will clarify all your doubts.

St : That sounds to be a nice idea ,sir. So my first question is “How do we define computer” (simple definition)?

Te : “computer is an electronic machine”. This would be the simplest definition for computers.

St : Why did the name “computer” given for this machine?

Te : In Greek Language the word “compute” means “to calculate”

Computer was basically invented only as a colculational engine, it got the name computer. Of course now it has become a dynamic machine with umpteen uses, but still that old name continues...

St : sir, why should we use computers. Can you justify this?

Te : Sure Kanna, this can be certainly justified.

To be continued...
