The first generation of computers were room-sized machines that consumed large amounts of electricity and generated significant heat, causing frequent malfunctions. The second generation introduced transistors which helped computers become smaller. The third generation saw the addition of keyboards and monitors, making computers accessible to the mass audience for the first time. Each generation of computers has become increasingly smaller, cheaper and more powerful due to major technological developments.
