  6. Third Generation • IntergreatedCircuit(IC) was invented in 1958 • Jack Kilby

  7. Fourth Generation(1971-Present) • modern day computers • The size started to go down with the improvement in the integrated circuits

  8. Fifth Generation (Present and Beyond) • only in the minds of advance research scientists and being tested out in the laboratories • computers will be more powerful than those under central processing • future looks bright for the computers
