Computer generation
The term "generation of computers" refers to distinct phases in the development of computing technology, each characterized by significant advancements in hardware and, more recently, software . There are five generally recognized generations, each marked by a key technology that defined its era: 1. First Generation (1940s-1950s): Vacuum Tubes Key Technology: Vacuum tubes were the core component. Characteristics: Large, expensive, unreliable, and generated a lot of heat. Examples: ENIAC, UNIVAC. 2. Second Generation (1950s-1960s): Transistors Key Technology: Transistors replaced vacuum tubes. Characteristics: Smaller, faster, more reliable, and consumed less power. Examples: IBM 1401. 3. Third Generation (1960s-1970s): Integrated Circuits (ICs) Key Technology: Integrated circuits, combining multiple transistors on a single chip. Characteristics: Significantly smaller, fas...
