The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often __________, taking up entire rooms. They were very expensive to operate and in addition __________ a great deal of electricity, __________ a lot of heat, which was often the cause of malfunctions. Transistors, invented in 1947, replaced __________. They allowed computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Second-generation computers moved from __________ language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words.

The development of __________ was the hallmark of the third generation of computers. Transistors were miniaturized and placed on __________, called semiconductors, which __________ the speed and efficiency of computers. Instead of punched cards and printouts, users interacted with third generation computers through such __________ devices as keyboards and monitors. This allowed the device to run many different applications __________ with a central program that monitored the memory. Computers for the first time became __________ to a mass audience because they were smaller and cheaper than their predecessors.
