In the evolution of computers their first generation was characterized by the use of vacuum tubes. These computers were expensive and bulky. They used machine language for computing and could solve just one problem at a time. They did not support multitasking.
In the 1960s, transistor based computers replaced vacuum tubes. Transistors made computers smaller and cheaper. They made computers energy efficient. But transistors were responsible for the emission of large amounts of heat from the computer. Due to this computers were subject to damage. The use of transistors marked the second generation of computers. Computers belonging to this generation used punched cards for input. They used assembly language
