How does the shell work with the kernel?
I THINK KERNAL IS THE INNERMOST PART OF THE COMPUTER. AND ALL REATED TO HARDWARE MEANS TIME SHARNG,MEMORY MANAGEMENT ETC IS DONE BY KERNAL. WHILE SHELL IS OUTER MOST PART OF COMPUTER. IT ACTS AS AN INTERFACE B/W USE AND OS. IN B/W KERNAL AND SHELL THR IS OS. O.S IS IN BETWEEN KERNAL AND SHELL ====================== I will take it this way... Superficial idea about the shell communication is very simple. Shell is a program(for Linux a process) which has been written to using the Kernal modules(Kernal is again a software program consist of many module).Kernal module provides different API which the shell programmer use to call depending upon the command placed by the user. Writting our own shell is bit difficult as it need through understanding of how the kenel behaves.

what do you mean by internal memory ? Read only memory is a thing which acts as a interface between kernal and interfacing hardware... it helps passing orders from the kernal to the hardware and makes it work ! i guess this definitely fitting in the category of the internal memory but it is not used as a storing the user's data for his personal use ..!

When popcorn pops?
When the water inside the kernal turns to steam, the steam cannot escape through the kernal's hard shell, so the kernal explodes like a hand grenade. The liquid starch inside spews in all directions, and is instantly cooked by the steam into the puffy, delightful balls of goodness we all enjoy munching at the movies. Water boils at 212 degrees Fahrenheit or 100 degrees centigrade, so whatever brings the kernal up to that internal temperature without burning it will make the kernal pop.
