Q1: What is the name of the chip which has more than once processor on it?

ANS:C - Transputer

The transputer was a pioneering microprocessor architecture of the 1980s, featuring integrated memory and serial communication links, intended for parallel computing. It was designed and produced by Inmos, a semiconductor company based in Bristol, United Kingdom.

For some time in the late 1980s many considered the transputer to be the next great design for the future of computing. While Inmos and the transputer did not ultimately live up to this expectation, the transputer architecture was highly influential in provoking new ideas in computer architecture, several of which have re-emerged in different forms in modern systems.
