Explanation:

In the 1950s and 1960s, computers used vacuum - tube technology. Vacuum - tube computers were large in size (occupying entire rooms in some cases) and had relatively slow processing speeds compared to modern computers which use integrated circuits. Also, they were expensive. Modern computers are smaller, faster, and more cost - effective.

Answer:

They were bigger and slower.
