Computers are combined with hardware and software which communicates with each other. The first thing the system should do is to trigger Kernel for the initial setup for both software and hardware management once the device powers up. At the core level of all computers, it needs first uploading of both kernel and system drivers. Most people can be quite intimidating about understanding the kernel and device drivers. So once you begin to understand the Kernel’s basic definition, you can start thinking about the basic programming tutorials for the system driver, and so on. Let’s start with a simple kernel- and system driver definition.


Understanding Kernel

Any operating system has a kernel as an integral part. The kernel is one of the first programs to load up during initialization on any computer. It makes the interaction between the software and the hardware easier. Kernel communicates on a basic level with the hardware before it starts communicating with the applications. The kernel is a very important computer part, and has a separate memory area of its own. Where the kernel is protected against all (I.E. changes in software and hardware). Once the kernel is loaded, management of application programs and system resources will begin. It’s best not to modify the kernel until you completely understand its capabilities or unintentionally trigger the device to become unstable. It could theoretically cause a crash.

Understanding Driver Device

The kernel will start something called the BIOS (basic input / output system) within the initial setup. It is where the kernel first loads the various computer drivers, before loading the operating systems. Until computers start uploading applications, the system drivers will include a processor, motherboard, and other hardware. Should you wish to start learning about programming the system driver, I would suggest learning through Linux and its tutorials. Again you don’t want your computer program to cause any instability. Linux will allow virtual simulation to test your programming for your system drivers using their “Kernel Modules.” Linux uses the language of C-programming and I would recommend learning it (Please do not get confused with the language of Microsoft programming called C++.

Let’s have a look

To conclude, Kernel is inserted into the system to ensure from the start that all systems operate properly. The machine has no way of handling the hardware resources for its applications without the Kernel. The kernel is usually well shielded from any external changes, which they have separate memory space dedicated to. There are device drivers inside the kernel which upload the system BIOS. This would ensure that the hardware system is running and that the operating system / applications are then installed to ensure smooth running by the Kernel. I would highly recommend that you start learning through C-programming and go through several tutorials to grasp the general concept of device driver programming, so that you don’t create any instability or crashes on your computer system. Last but not least, Linux is surely the best place to start your programming adventure.
