The Linux kernel communicates between the hardware and applications via "interrupts." When the hardware wants to interface with the application and broader system, an interrupt is issued across the processor and kernel to manage resources efficiently. The kernel, existing inside a hard OS shell, con...

The system memory in the Linux kernel is segregated into kernel space and user space. The kernel space is the access-protected memory area reserved for executing the core of the OS in Kernel Mode, whereas user space is the system memory where user processes execute in User Mode. The CPU ca...
1) Linux Kernel Lockdown The principal feature addition on Linux kernel 5.4 is the kernel lockdown mode which aims to enhance Linux kernel security by separating the userland and kernel code. The kernel lockdown limits the root (UID 0) account access to kernel features that enable arbitrary co...
“How can we find out how many NICs are installed in our Redhat host without checking it physically?” As with everything else for Linux, there is a command that can do the trick for you and reports all the NIC cards that have been detected by the kernel. Below is all the commands ...
A Linux distribution (sometimes abbreviated as “Linux distro”) is a collection of key and optional components that combine to form a complete operating system. Generally, a Linux distribution includes core components including a bootloader, a Linux kernel, an init system, daemons, a graphical se...
