What is a Process in Linux?
In Linux, a process is a running instance of a program. When you execute a program, it becomes a process, an independent, executing entity with its own memory space. Each process is assigned a unique identifier, the Process ID (PID). Processes are fundamental to the functioning of the operating system and play a crucial role in multitasking, allowing the computer to execute multiple tasks concurrently.
