Answer 1

The correct answer is SISD.

Key Points

The Von Neumann architecture is a computer architecture design based on a 1945 description by the mathematician and physicist John von Neumann.
This architecture is also known as the stored-program computer concept.
The design consists of a single memory space that holds both instructions and data.
It operates sequentially, which means one instruction is processed at a time, which is characteristic of Single Instruction Single Data (SISD).
This sequential processing makes the Von Neumann architecture less complex but can also be a bottleneck (known as the Von Neumann bottleneck).

Additional Information

In contrast to Von Neumann architecture, Harvard architecture has separate memory spaces for instructions and data, allowing simultaneous access to both.
Modern computer systems often use a modified Harvard architecture to improve performance.
The Von Neumann architecture is fundamental to the design and functioning of most traditional computers and has greatly influenced computer science and engineering.
The concept of stored-program computers allows for greater flexibility and programmability compared to earlier computing machines that required manual reconfiguration.
