A process in Linux is an instance of a running program. When you execute a command or launch an application, the operating system creates a process to run that program. This process includes the program code, current activity, resources it uses such as memory and open files, and its position in the system’s process hierarchy. Each process is uniquely identified by a Process ID (PID). Additionally, processes have attributes like parent process ID (PPID), priority, memory usage, CPU time consumed, and open files. Linux manages these processes independently but allows…
