True or false computer introduction

Question

a. Applications requiring complex, sophisticated mathematical calculations use mainframes

b. Instead of the term, port, the term, connector, sometimes is used to identify audio and video ports

Answer 1

a.

Computers called 'mainframes' are typically used for business applications.

Namely those involving movement of a lot of data, calling for extra level of reliability.

They could be used for 'complex, sophisticated mathematical calculations', but not necessarily.

Such calculations usually call for large amount of parallelism, achieved by 'supercomputers'.

And those lately rely on GPUs.

b.

It is possible that some people do use those two terms interchangeably, but I have not heard that, and

I would find it confusing.

A 'port' is on a device, and a connector plugs into a port.
