Scheduling in Linux is a mixture of various scheduling strategies and scheduling algorithms, because different types of processes have different scheduling requirements, so the timing of scheduling is also different. These algorithms allow the system to run more eff

To say clear Systemd, you have to start with the Linux operating system started speaking. The startup of the Linux operating system starts with the BIOS, then the boot Loader loads into the kernel and initializes the kernel. The final step in kernel initialization is to start the init process. This process is the first process of the system, PID 1, also known as
