Explanation:

Transistors, invented in the 1940s but widely - used in the 1950s, replaced vacuum tubes in electronic devices. They were smaller, more reliable, and consumed less power, which was crucial for the development and miniaturization of electronic computers. The Internet was developed later; personal computers became prominent in later decades; radio transmitters are not directly related to the rise of electronic computers in the 1950s.
