I am new to Linux. I guess everyone here knows Dennis Ritchie's basic hierarchy for Unix: Kernel, Shell & Utilities.
Given a server bundle (such as LAMP) isn't part the kernel but also isn't part of its shell (Services), than on what layer is it actually?
I wouldn't say these are utilities since they have their own utilities to control them (either within the shell terminal or shell GUI which are utilities themselves).
I thus conclude that a server software is actually somewhere "between" the shell/utility layers, if we follow Ritchie's hierarchy, Would you deem that correct ?
