What is a Unix kernel?

An object is a data structure that represents a system resource, such as a file, thread, or graphic image.

Instead, an application must obtain an object handle, which it can use to examine or modify the system resource.

What is Modules_install?
sudo make modules_install is a step in building your own Linux kernel. Many parts of the kernel can be built into the k. This is a command you’d run once you’ve build the Linux kernel to install the parts of the kernel that you had built as modules instead of being built into the kernel.
Where do I put kernel modules?
On boot, the kernel will try to load all the modules named in this file. Copy the module to a suitable folder in /lib/modules/`uname -r`/kernel/drivers . In my case this was /lib/modules/`uname -r`/kernel/drivers/pci . This will place the module in modprobe’s database.
