single instruction single data (computer) (SISD)
The classification ofcomputer architectures refers to all work and instruction structures relating to internal data processing.
In the case of Single Instruction Single Data (SISD), this is an architecture in which a processor can execute an instruction with the data of a data set. The instructions are processed one at a time, one after the other.
The SISD architecture is the classic architecture of a serial computer in which operations are processed sequentially. It has the advantage that its structure is not tailored to a specific application and therefore it can be adapted to a wide variety of applications. The architecture corresponds to that of a personal computer( PC).
The SISD concept corresponds to the original Von Neumann computer.
