run between $50.00-$150.00 us dollars per each license copy.

The majority of Linux variants are available for free or a much lower price then Microsoft Windows.

Linux KernelLinux a monolithic but modular system. Modularity is supported in two ways. Compile-time options. Most kernel components can be built as a

dynamically loadable kernel module(DLKM).DLKMs Built separately from the main kernel. Kernel modules can be upgraded

incrementally.

Windows KernelWindows is a monolithic but modular system. No protection among pieces of kernel code

and drivers.Support for modularity is somewhat weak.Windows drivers are dynamically loadable

kernel modules. Built independently from the kernel. Can be loaded on demand.
