Questions about Kernel

Hi experts, good day. :)

Obviously I'm new in Linux. My questions are all about Kernel.

Here are my questions:

1. What is a Kernel?
2. Where can I find the Kernel?
3. What is the main function of the Kernel?
4. Do other Operating Systems have also a Kernel?
5. It is said that Linux is came from the Kernel, that's why Linus Torvalds called his OS name "Linux"?.
6. Does it mean that the name of Kernel program is "Linux"? So other Operating Systems as well are using Linux?

I'll wait for your answers guys.

Take care and God bless. :)

Yes all OS use a kernel. http://en.wikipedia.org/wiki/Kernel_(Linux)

Number 5, Linux was made from Minix, Linus used his name, and called it Linux. All OS'es use a Kernel, but Linux is the only one that uses the Linux Kernel. Windows has a kernel, but it is the windows kernel.

Ok now I got it.

Questions:

1. Where can I find the Kernel in Linux?
2. Where can I browse? So that I will know where's the Kernel located.

You can find kernel updates and news here: http://www.kernel.org/ Your kernel is listed within the /usr/src directory.

Thanks for the link Sir. I have questions again.

1. Do I need to update the Kernel Sir?
2. Is it really important to update the Kernel and Why?

Tha Mac has the Darwin Kernel

Thanks Sir jepong for the added info that you posted.

Just want to update my questions.

a computer system is composed of three(if im not wrong) layers: Operating System(Linux/Mac/Windows), Kernel, and Hardware.. So the Kernel is the bridge between your OS and your Hardware. :)

The kernel package contains the Linux kernel (vmlinuz), the core of the Red Hat Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, processallocation, device input and output, etc.

1. Do I need to update the Kernel Sir?

If it's only necessary

Tutal, nasagot na naman ang karamihan sa mga tanong (at hindi ko din naman alam ang mga sagot), magpapatawa na lang ako:

Ano ang Kernel? Ang rangong sumusunod sa Lootenant Kernel at sinusundan ng Heneral.

Saan makikita ang Kernel? http://ubuntuforums.org/member.php?u=72837

Kailangan bang i-update ang Kernel? Depende. Interesado ba siya sa ia-update mo sa kaniya? :D

A.3 Why upgrade?

There are several reasons to upgrade your kernel. Most of the reasons are that you perhaps need a new device driver for your new or old hardware (the previous device driver could have had a bug somewhere) or you need to upgrade due to a bug in the kernel (security one or a non-security one). Usually new kernels run faster than the old ones and are more stable and reliable. (http://www.faqs.org/docs/lnag/lnag_kernel_upgrade.html) Some reading for ya........
