A system architecture or systems architecture is the conceptual model that defines the structure, behavior, and more views of a system.

A system architecture can comprise system components, the expand systems developed, that will work together to implement the overall system. There have been efforts to formalize languages to describe system architecture, collectively these are called architecture description languages (ADLs).
