Point-contact transistor
→
Vacuum tube
replaces
The point-contact transistor required no filament warm-up and was smaller and less power-hungry, demonstrating a path toward replacing vacuum tubes with solid-state switches.
Transistorized computer
→
Vacuum tube
replaces
By the late 1950s, transistorized computers had begun replacing vacuum-tube designs in general-purpose computing.
