i.Supercomputers are a special class of mainframe
ii. Mainframes are designed for very high quantities of general processing
iii. Supercomputers are optimized for extremely complex central processing
iv. Supercomputer’s possibly massive number of processes may be custom designed to allow a large number of very highly parallelized copies of a particular application

A.
i, ii

B.
ii, iii

C.
None of them

D.
All of them

Explanation:
Supercomputers might be considered a special class of mainframe. They
share many architectural similarities, but where mainframes are designed for very
high quantities of general processing, supercomputers are optimized for extremely
complex central processing (which also happens to require the vast I/O capability of
the mainframe architecture). Where a mainframe’s several processors will balance the
load of a very high number of general processes, a supercomputer’s possibly massive
number of processes may be custom designed to allow a large number of very highly
parallelized copies of a particular application to communicate in real time, or a
very small number of extremely complex scientific algorithms to leverage vast
amounts of data at once.
