This system architecture is a conceptual model that describes the structure and behavior of multiple components and subsystems of a system, such as various software applications, network devices, hardware, and even other system machinery. Architecture Description Language (ADL) aids in the description of the overall system architecture. As a result, it is a much broader topic. The architectural organizations of a system can be broadly classified as centralized or decentralized. Two closely related components can be co-located or placed on different machines. The placement of elements has an impact on performance and reliability.
