🧠 Explanation:
Second-generation computers, used in the late 1950s to 1960s, relied on transistors instead of vacuum tubes. Transistors made computers smaller, faster, and more reliable, marking a technological leap. This era is a key topic in computer history, engaging students and tech historians. Understanding transistors’ impact highlights computing’s evolution, relevant for studying modern technology’s roots. Their role in advancing electronics attracts interest in how early innovations shaped today’s devices, from PCs to smartphones, in the digital age.
