Akshay Siwalakshay-siwal.hashnode.dev·Nov 17, 2024Linux VFS Explained: How It Simplifies File Access Across Multiple File SystemsThe Virtual File System (VFS) serves as an abstraction layer that allows the kernel to interact uniformly with different file systems (ext4, XFS, NFS, etc.). VFS provides a consistent interface for user-space applications to perform file operations l...DiscussLinux

Faizan Shaikhfaizanshaikh.hashnode.dev·Oct 8, 2024Day 4 - Basic Linux Shell Scripting for DevOps EngineersWhat is kernel? A kernel is like the "boss" of your computer. It controls everything that happens inside the computer, making sure that different parts, like your programs and hardware, can work together smoothly. Imagine your computer as a big compa...Discuss·1 like·147 readsLinux
Harsh Agarwallinuxkernel.hashnode.dev·Oct 3, 2024Linux Kernel SchedulerThe point of this article is to give you a brief on how the Linux scheduler works. The Linux kernel scheduler may seem complex initially, partly due to its modular nature. It allows multiple scheduling algorithms to coexist to manage different classe...DiscussLinux
