Computers have evolved through different generations, each marked by advancements in technology. The generations of computers are generally classified as follows: First Generation (1940s-1950s): Vacuum tubes were used for processing. ENIAC, the first electronic general-purpose computer, is an example. Large in size, consumed a lot of power, and generated significant heat. Second Generation (1950s-1960s): Transistors replaced vacuum tubes, reducing size and heat. Assembly language and high-level programming languages were introduced. IBM 1401 and UNIVAC 1108 are examples. Third Generation (1960s-1970s): Integrated Circuits (ICs) brought further miniaturization and improved efficiency. The introduction of operating systems and high-level languages like COBOL and FORTRAN. IBM System/360 and PDP-11 are examples. Fourth Generation (1970s-Present): Microprocessors allowed the creation of personal computers. GUIs (Graphical User Interfaces) and networking became widespread. IBM PC, Appl...
