Instructions were necessary for every aspect of the computing job. 2nd Generation computers : Fayetteville High School 2008-2009 R. Stewart 2nd Generation computers Used transistors. Transistors performed functions similar to vacuum tubes, but they were smaller, cheaper, less power-hungry, and more reliable. Ran programming language compilers. Used English like commands rather than binary numbers. Made it possible to develop software. 3rd Generation computers : Fayetteville High School 2008-2009 R.
