What is Operating System is?

In the sweet memory of "Miss Pushpa Mamoria", my OS teacher who inspired me to write this poem...

  What is operating system is????

She was a bit nervous, and had a pale face...
But too much of makeup left no trace..
As she eased her bulk on the chair..
We cudn't do anything else to stare..

"this is the subject i will teach u..
and the subject code is three three two."
Before i cud guess the direction of the breeze...
She pointed me and said "Yesss plzzzzz"
"What is operating system is??"

I sat dumbstruck for a while,
n she said that with a cunning smile..
Self study must be ur hobby..
n u r supposed to make a tutorial copy.

Her profile was a real exception..
She was fond of playing "Bad Minton"
n had won prize in "Hand-writing" competition..
Her hobby was watching advertisements..
She used c++ as software,that too was a compliment...

Answering the questions she was so much at ease;;
the only thing she said was..
"Who will explain thiss"
And i thought if i cud know
"What is operating system iss??"

The next class i will deal with "process management"
you sud go in prior through the content..
I owned the courage n took the pain..
To ask a question she cudn't explain...
She gave me a horrifying look...
"It's not there in the book"

There has been enough of rest
today u have a surprise test
there is so much that she did...
BUT I CUDN'T UNDERSTAND
"WHAT IS OPERATING SYSTEM ISS??"

Beautiful she was i guess..
But the way she dressed was a mess..
The only time she looked hot,
was when she took a chance...
and came with us in the party to dance...

The ugly dimples n the small grin..
Terror she is like "Bandit Queen"..

By this time I know what she is
But I still do not know
"WHAT IS OPERATING SYSTEM IS??"
But I still do not know
"WHAT IS OPERATING SYSTEM IS??"
