Answer 1

Answer :Von Neumann

SIMD : Short for single instruction, multiple data. A type of parallel computing architecture that is classified under Flynn's taxonomy. A single computer instruction perform the same identical action (retrieve, calculate, or store) simultaneously on two or more pieces of data

Answer 2

→ Single instruction, multiple data (SIMD) is a class of parallel computers in Flynn's taxonomy. It describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously. Such machines exploit data level parallelism, but not concurrency: there are simultaneous (parallel) computations, but only a single process (instruction) at a given moment
→ The von Neumann architecture is also known as the von Neumann model or Princeton architecture consists of the following components:
->A processing unit that contains an arithmetic logic unit and processor registers
->A control unit that contains an instruction register and program counter
->Memory that stores data and instructions
->External mass storage
->Input and output mechanisms
