Difference Between Kernel and Shell

A Kernel is a computer program that is the heart and core of an Operating System. Since the Operating System has control over the system so, the Kernel also has control over everything in the system. It is the most important part of an Operating System. Whenever a system starts, the Kernel is the first program that is loaded after the bootloader because the Kernel has to handle the rest of the thing of the system for the Operating System. The Kernel remains in the memory until the Operating System is shut-down.

Novell, Inc. Unix systems are characterized by a modular design that is sometimes called the " Unix philosophy ". According to this philosophy, the operating system should provide a set of simple tools, each of which performs a limited, well-defined function.

Unix Vs. Linux: What’s the Difference Between Unix and Linux?

Each computer system includes a basic set of programs called the operating system. The most important program in the set is called the kernel. It is loaded into RAM when the system boots and contains many critical procedures that are needed for the system to operate. The other programs are less crucial utilities; they can provide a wide variety of interactive experiences for the user—as well as doing all the jobs the user bought the computer for—but the essential shape and capabilities of the system are determined by the kernel. The kernel provides key facilities to everything else on the system and determines many of the characteristics of higher software. Interact with the hardware components, servicing all low-level programmable elements included in the hardware platform.

Консульство этого так не оставит. - Надеюсь. - Месье Клушар.  - Беккер улыбнулся и достал из кармана пиджака ручку.  - Я хотел бы составить официальную жалобу городским властям.

То же самое будет и со мной, - подумала. Сьюзан вспомнила о единственном остающемся выходе - личном лифте Стратмора. Но она понимала, что надежды нет: электроника вряд ли уцелела после катастрофы. Двигаясь в дыму, она вдруг вспомнила слова Хейла: У этого лифта автономное электропитание, идущее из главного здания. Я видел схему. Она знала, что это. Как и то, что шахта лифта защищена усиленным бетоном.


Both the Shell and the Kernel are the Parts of this Operating System. These Both. Parts are used for performing any Operation on the System.


What is a shell?

Она взглянула на работающий монитор. Он по-прежнему показывал время, превышающее пятнадцать часов. Даже если файл Танкадо будет прочитан прямо сейчас, это все равно будет означать, что АНБ идет ко дну. С такими темпами шифровалка сумеет вскрывать не больше двух шифров в сутки. В то время как даже при нынешнем рекорде - сто пятьдесят вскрытых шифров в день - они не успевают расшифровывать всю перехватываемую информацию. - Танкадо звонил мне в прошлом месяце, - сказал Стратмор, прервав размышления Сьюзан. - Танкадо звонил вам? - удивилась .

Беккер заговорил по-испански с сильным франко-американским акцентом: - Меня зовут Дэвид Беккер. Я из канадского посольства. Наш гражданин был сегодня доставлен в вашу больницу.
