The Kernel
The Kernel
Most computers nowadays do not store any portion of the operating system in ROM. Among those that did and still do, only the kernel and basic system libraries are placed in ROM.
A PC going through its booting sequence upon staring, a personal computer's CPU runs the instruction located at the memory location of the Basic Input/ Output System (BIOS). It contains a jump instruction that transfer execution to the location of the BIOS startup program. This program runs a Power On Self Test to check that devices the computer rely on are functioning; it also initializes these devices. Then the BIOS go through a preconfigured list of devices until it finds one that is bootable. If the BIOS find a bootable device, it loads and executes its boot sector. In the case of a hard drive, this is referred to as the master boot record (MBR) and is often not operating system specific. Usually MBR code checks the partition table for an active portion. If one is found, the MBR code loads that partition's boot sector and executes it. The boot sector is often operating system specific, however in most operating systems its main function is to load and execute the kernel, which continues startup and in the case of multi-user operating systems prompt the login screen.
GNU is a Free Software project which is essential to the Linux operating system. It is a project that provides and distributes a lot of the software which is essential to making a fully-functional operating system distribution based upon the Linux kernel. For example, the Linux tools/commands that allow you to enter and run commands, copy files from one directory to another, compress and uncompress files, search for strings within text files, and mount and unmount filesystems are all GNU-provided tools. In short, GNU is a project which provides a major portion of the base Linux operating system - besides Linux itself which is the kernel and is provided by a separate project. It does not however provide the entire rest of the operating system; primarily just the type of basic tools mentioned above (although a very lot of them). Some GNU software has also been ported to run on other operating systems also. Some people refer to the Linux operating system as GNU/Linux to reflect the major contribution which GNU provides to that operating system.
