The lesser the arrival time of the job, the sooner will the job get the CPU. Most of the Unix and Linux commands are similar in nature. An operating system or OS is system software that works as an interface between hardware components and end-user. Linux file system allows us to operate various operations on files like create, edit, rename, remove. 1) What is Linux? The resource allocation graph is the pictorial representation of the state of a system. Compilers and editors run in user mode, whereas operating system code runs in kernel mode.
