According the the Flynn$\text{'}$s Taxonomy, a SIMD computer architecture

Select one:

a$.$ performs the same operation on multiple data items simultaneously. Modern

architectures exploit data$-$level parallelism by incorporating this model into vector units

within each core.

b$.$ uses multiple processing elements to execute different instructions on different data

streams. Modern microprocessors use this model by incorporating a number of cores $[$or

streaming multi$-$processors$]$ that can execute threads synchronously and independently.

c$.$ refers to the traditional von Neumann architecture where a single sequential

processing element operates on a single stream of data. Instructions are processed

sequentially; hence computers adopting this model are popularly called sequential

Computers.

d$.$ uses multiple processing elements to execute different instructions on

different data streams. Modern microprocessors use this model by incorporating a

number of cores $[$or streaming multi$-$processors$]$ that Lan execute threads

synchronously and independently.
