Generation computer
1. First Generation (1940s-1950s): The first electronic computers used vacuum tubes for circuitry and were quite large and inefficient. ENIAC (Electronic Numerical Integrator and Computer) is an example of a first- generation computer.
2. Second Generation (1950s-1960s): Transistors replaced vacuum tubes, leading to smaller and more r eliable computer s. This era also saw the introduction of magnetic core memory. IBM 1401 and UNIVAC 107 are examples of second-generation computers.
3. Third Generation (1960s-1970s): Integrated circuits (ICs) emerged, combining multiple transistors on a single chip. This made computers smaller, faster, and more energy-efficient. IBM System/360 and DEC PDP-11 represent the third generation.
4. Fourth Generation (1970s-1980s): Microprocessors, incorporating the entire CPU on a single chip, became widespread. Personal computers (PCs) and home computers were introduced during this era. Examples include the Apple II and IBM PC.
5. Fifth Generation (1980s-Present): The focus shifted towards artificial intelligence and parallel processing. Technologies like neural networks and expert systems gained prominence. The fifth generation is ongoing and involves various advancements in computing, including parallel processing, AI, and quantum computing
