Which is used for manufacturing chips?

  • A.Bus
  • B.Control unit
  • C.Semiconductors
  • D.A and b only

Answer: C

Correct answer: Semiconductors

Chips are fabricated from semiconductors, silicon above all. A semiconductor conducts only under certain conditions, and it is that controllability - achieved by doping the crystal with impurities - which makes a transistor, and so a switch, possible. Buses and control units are things built from chips.
