what is difference between kernel and shell?
Answer Posted / reenadevi
A shell is a command interpreter, i.e. the program that either process the command you enter in your terminal emulator (interactive mode) or process shell scripts (text files containing commands) (batch mode). In early Unix times, it used to be the unique way for users to interact with their machines. Nowadays, graphical environments are replacing the shell for most casual users.
A kernel is a low level program interfacing with the hardware (CPU, RAM, disks, network, ...) on top of which applications are running. It is the lowest level program running on computers although with virtualization you can have multiple kernels running on top of virtual machines which themselves run on top of another operating system.
