A system configuration (SC) in systems engineering defines the computers, processes, and devices that compose the system and its boundary. More general the system configuration is the specific definition of the elements that define and/or prescribe what a system is composed of.Alternatively the term system configuration can be used to relate to a model (declarative) for abstract generalized systems. In this sense the usage of the configuration information is not tailored to any specific usage, but stands alone as a data set.
Why is a properly- configured system necessary?
A properly-configured system will allow you to avoid nasty resource conflict problems, and make it easier for you to upgrade your system with new equipment in the future. An improperly-configured system will lead to strange errors and problems, and make upgrading a nightmare.
