Kernel Development refers to the process of creating and maintaining the core component of an operating system, known as the kernel. The kernel acts as a bridge between the hardware and software, managing system resources and enabling communication between applications and the computer's hardware. Developers involved in kernel development work on various tasks, including improving performance, enhancing security, and adding new features. This work often requires a deep understanding of computer architecture and programming languages like C and Assembly. Popular kernels include the Linux kernel, which is widely used in many operating systems, including Ubuntu and Android.
