Because of
this, they perceive the operating system and the hardware of their computer as being
married together in an inseparable union. You may have heard someone refer to his
or her computer as a ???Windows computer.???
Actually, the computer hardware and the operating system are independent of each
other. That??™s because the modern PC is modular in nature. The Windows operating
system can be easily removed from the system and any compatible operating system
can be installed in its place, including DOS, Windows, Linux, Solaris, and even Mac
OS (if you install a special expansion board with the appropriate ROM chip).
The Linux operating system is composed of the following components:
?– The Linux Kernel This is the heart of Linux; hence it is called the kernel.
The kernel is the actual operating system itself. It??™s the component that
fulfills the key operating system duties discussed above.
?– Libraries Libraries are pre-written code ???pieces??? that application
programmers use in their programs. As we discussed earlier, this can be a huge
time saver. Imagine what would happen if you were a programmer and you
had to include code in your applications that would allow it to work with
every type of hard disk drive interface currently on the market.
