Linux-based operating systems, like all other operating systems, have processes and services that run while the machine is on. These range from various operating system services, to the command line, to different services/daemons designed to maintain the system and keep it running smoothly. Most services are vital to a process’ normal operation, ranging from helper services to special services designed to handle input, improve performance, offload resources, etc. Processes are also the backbone of a computer’s core functionality, making it important to have the resources for them all.
