Nope, a kernel is a kernel, which is a component of an operating system. An operating system consists of a kernel along with other components which manage the system and hardware resources and which manage the sharing of common resources between multiple users and/or applications. It would also include utilities for configuring and administering the above components. That includes at least the components I mentioned in my previous message (basic library, login/logout managers, shell, system logging, basic networking daemons, etc.) > The OS + userland utilities might accurately be > called an operating environment I don't know what an "operating environment" is.

Absolutely right, but that usually includes other components besides just the kernel (an exception might be made for very limited embedded -- usually single purpose -- devices where everything needed to manage the hardware is contained in the kernel).
