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.

Tips are as follows.
1. Start your programme always with comments like name of programe, purpose and date of code creation.
2. Put comments on each step which is important and easy to understand for others also.
3. Put indentation after looping statement and if else condition.
4. Do not use keyword as a variable name.
5. Use variables name meaningful like if you want to write variable for name of student then you should write variable as StudentName.
6. Use same format type for all variable like if you use first letter of variable as capital letter then keep this thing with other variable also.
7. Keep your programme in proper folder to get easily when you want to open your programme next time.
8. Try to reduce your code for same output e.g. you do not need to write add function more than once if its result is same.
9. Put space between ending of each fuction.
10. Keep discussion with other programmer.
In India, day by day information technology is going to be expanding in a broad sense. In each business, use of technology is very common thing. It is not only used at business places but is also used for providing homogeneous facility to the one.
The combination of creativity of one's mind with his/her technical knowledge results in research of required products.

following thing should be in mind
(a) Is system is technically feasible.
(b) Is system is financially feasible.
(c) Time feasibility.
(d) If system is feasible then start to study system and make document as per details.
2. Second step is to make data flow diagram of system then pert and Gant chart is also part of you project.
3. Prepare and make flowchart of logic flow of main modules.
4. decide table as per your DFD and flowchart.
5. Normalize database.
6. Then system design process will start.
7. As per design and requriement code can be write.
8. Solve any error if it comes.
9. Put system for testing.
10. Make modification if any error fetched by tester.
