Q1. Describe the various generations of computers along with their key characteristics.
- First Generation (1940s-50s) used vacuum tubes; large, slow, machine language.
- Second Generation (1950s-60s) adopted transistors; smaller, faster, assembly/high-level languages.
- Third Generation (1960s-70s) introduced Integrated Circuits (ICs); increased speed, efficiency, operating systems.
- Fourth Generation (1970s-Present) utilized microprocessors (VLSI); enabled PCs, GUI, internet.
Answer: The evolution of computers is categorized into generations, each marked by significant technological advancements that drastically altered their capabilities, size, cost, and efficiency. These advancements have progressively made computers more powerful, compact, and accessible. The **First Generation (1940s-1950s)** utilized vacuum tubes for circuitry and magnetic drums for memory. These computers were enormous, slow, expensive, and generated considerable heat, consuming vast amounts of electr...
