Architecture - (System Architecture) - Computerized device’s architecture is not only its design as a concept but the fundamental operational structure of it as a computerized system. It’s also the arrangement of the system’s parts. This includes television systems with interactivity. If you set a device up to have two serial ports then you can say, “its architecture has two serial ports.”

Computer architecture is comprised of at least three main subcategorizes: Microarchitecture, Instruction Set Architecture (ISA) and the System Design.
