Understanding Cache Coherency in the Linux Kernel
Cache Coherency is a critical concept in modern multi-core processor systems that ensures data consistency across multiple caches in the system. In a multi-core system, each CPU core often has its own private cache, and ensuring that all cores see the same data, even when it is cached locally, is essential for system stability and…

Understanding Device Drivers in the Linux Kernel
Device drivers are a fundamental part of the Linux kernel, serving as a critical bridge between the hardware components of your computer and the operating system. Without device drivers, your system wouldn’t be able to communicate with or control hardware devices like keyboards, hard drives, network cards, and graphics cards. In this article, we’ll explore…

Understanding the Linux Kernel Scheduler
The Scheduler is one of the most critical components of the Linux kernel, responsible for managing how processes (also known as tasks) are allocated CPU time. It ensures that multiple processes can share the CPU effectively, balancing performance, responsiveness, and fairness. The scheduler determines which process runs on the CPU at any given time, ensuring…
