The evolution of computers is categorized into five generations , each marked by significant technological advancements that revolutionized computing. Here's an overview: First Generation (1940s–1956) Technology Used: Vacuum Tubes Characteristics: Relied on vacuum tubes for circuitry and magnetic drums for memory. Large, bulky, and consumed significant power. Generated a lot of heat and were prone to frequent breakdowns. Programming: Machine language (binary). Examples: ENIAC, UNIVAC. Applications: Basic calculations, military applications. Second Generation (1956–1963) Technology Used: Transistors Characteristics: Transistors replaced vacuum tubes, making computers smaller, faster, and more reliable. Reduced heat generation and power consumption. Programming: Assembly language and early high-level languages like COBOL and FORTRAN. Examples: IBM 1401, UNIVAC II. Applications: Business applications, payroll processing, and record-keeping. Third Generation (1964–1971) Technol...
