Third generation computers saw computing devices even more reduced in size and increased in efficiency and productivity. Transistors were miniaturized with the use of silicone chips. For the first time, computers were controlled by keyboards and included a screen interface, thus introducing familiar technologies, the typewriter and the television, into the computing experience. These new interface elements helped increase the comfortability of the the computer and paved the way for the introduction of the computer into all aspects of life. These computers included a primitive operating system and user interface that allowed users to interact with the computer in a way that related more closely to other aspects of human experience.
