Hey,
Can anyone tell me what are the different types shells and kernels present in both windows OS and linux.......

kernel is the main source of O.S.7 another side shells are the verbel media of O.s

Kernels are mainly of two types-Monolithic kernel and microkernel and shell is a command interpreter.There are several shells available such as Bash,korn,c etc.
