  5. Development History • Second Generation (2nd Generation) • 1955 to 1973, using semiconductor technology (transistors). • A computer system was created with these transistors smaller, faster and more efficiently than a computer system is made with vacuum tubes. • Third generation (3rd Generation) • 1974 to 1979, using IC (Integrated Circuit), a semiconductor circuit is established by transplanting the transistors on a substrate (silicon). • The first IC only 6 transistors (now with the Intel Pro to 5.5 million transistors). • MITS company in 1975 (USA) introduced the Altair personal computer in the world's first www.themegallery.com
