I have to make an rtos for 8051.
1.what are the functions performed by bootloader during startup of the chip? if i can execute a program on my chip stored at any location in memory then what do i mean by making a separate OS for 8051?
please help me..

The phrase "real time" by Websters definition basically means "NOW".
yes,,,thats why i call mine 'rapid time oparating system', it is quick but not instentanious. microprocessors are clocked and any action has to wait for next clock cicle. it cannot do stuff immideataly.
it cannot do stuff immideataly.
At the most basic level, no practical system can do anything immediately, since the speed at which information propagates is limited by c.
For any real system, however, having a delay that is a negligible fraction of the smallest time constant of the system does not violate the criterion for real-time.

Which is no more help than calling it "Real Time", is it?
"Rapid" is no more nor less specific than "Real Time", and just adds unnecessarily to the confusion by bringing a different name to the same concept!
"Rapid" in some systems will mean seconds; in others, it will mean nanoseconds.
no,,, real implies the poserbilty of immediate. Rapid implies quick (eg. not immidiate.) i use a better describing name of what the sw does. Rapid is more descriptave for the use bcoz it implies reletive time.
anyways,,, it do to me ;)-
