Computers have evolved from early mainframes to relatively small smart devices with high computing power. Which of the following inventions contributed to reducing the physical size of computers?
AVacuum tube
BIntegrated circuits ✓ Correct
CRegisters
DSolid state memory
Correct answer: (B) Integrated circuits — The answer is integrated circuits.
Explanation
★The answer is integrated circuits.
★An integrated circuit packs many electronic components onto a small chip of silicon.
★This replaced bulky separate parts and shrank computers greatly.
★So integrated circuits contributed to reducing the physical size of computers.
★Vacuum tubes were large and made early computers bulky.
★So the size reduction came from integrated circuits.
★So the answer is integrated circuits.
