Generations of computer

 Generations of computer

First Generation (1940s–1956): Used vacuum tubes, very large and slow, programmed in machine language. Example: ENIAC.

Second Generation (1956–1963): Used transistors, smaller and faster, introduced assembly and early high-level languages. Example: IBM 1401.

Third Generation (1964–1971): Used integrated circuits (ICs), more reliable, supported multiprogramming. Example: IBM System/360.

Fourth Generation (1971–1980s): Used microprocessors, led to personal computers, GUIs, and networking. Example: Apple II, IBM PC.

Fifth Generation (1980s–Present): Focus on AI, parallel processing, and portability, with modern PCs, smartphones, and cloud computing.
