Christian is working with a group of students that will be giving a presentation to the class about the evolution of digital computers. He has been asked to speak about second generation computers that were common in the 1950s and early 1960s. Which of these facts could Christian include in his presentation about second-generation computers?
These computers were the first to use a microprocessor known as a CPU.
These computers used vacuum tubes to supply electricity instead of relying on mechanical devices.
These computers used integrated circuits that replaced transistors.
These computers used small transistors to supply electricity instead of vacuum tubes, which meant they could be smaller, faster, and more efficient.
