    In modern OSs kernel is used to virtualize resources. For example, in Windows a thread virtualizes a CPU and a process virtualizes memory and IO space.

  • The computer is made up of hardware and software. Operating system is a system software which runs your apps like excel,word,etc. This operating system uses a program to interface with hardware peripherials and the BIOS. This program is known as kernel. The kernel takes command from the operating system and issues them in the form of control signals and instructions to BIOS to perform all the operations.

  • kernel is said to be the heart of an operating system..
    it interprets the commands given by the user and initiates the hardware of the system...
