Q3Computer Architecture
Question
Q.3. Define Computer Architecture.
Answer
Computer Architecture refers to the conceptual design and functional structure of a computer system, defining its instruction set, data formats, addressing modes, and the interface between hardware and software.
Computer Architecture is the study and specification of a computer system's functional behavior as seen by a programmer — encompassing the instruction set architecture (ISA), data types and formats, addressing modes, register organization, and I/O mechanisms. It defines the attributes visible to a systems programmer, distinct from computer organization (which deals with the operational, hardware-level implementation details like control signals and circuit design), and serves as the blueprint that both hardware designers and compiler/software developers use to ensure programs execute correctly on the machine.
