Explain When and Why the kernel will need to be recompiled

Immediately after installtion, you may encounter situations in which you are required to upgrade the system . Although the Linux kernel has seen many advances, it may not fulfill the needs of your system. for this reason, the kernel which is available at www.kernel.org is updated often.

You may have several reasons to update the kernel on your system, including the following:

• Stability : Although a released stable kernel is usually of high quality, many issues can still arise. This is why additional kernel releases are often more stable than the previous release

• Hardware support : You Probably need to upgrade to a version 2.4.* kernel or higher like 2.6 in order to achieve support for many of the new hardware devices that are available today.

• Hardware platforms : The newest processors often benefit from having the kernel optimized for their use. by providing an updated kernel, the system will be able to use the CPU more efficiently.

• Package support : Some software packages don't run well or don't even run at all on older kernel versions. and these packages are often required to use the linux system.

- Regardless of the reasons for upgrading the kernel, the installers should be competent at performing this task.
