Explanation:

Computers in the 1950s and 1960s used large - scale vacuum tubes and other bulky components, making them physically large. Also, their processing power was limited compared to modern computers, so they were slower. Modern computers use advanced microprocessors and miniaturized components, being smaller and faster.

D. They were bigger and slower.
