2.4 computational logic

1. inside a cpu,transistors are arranged and configured into circuits to perform operations such as calculations when electricity is passed through them.

   • for example, transistors can be arranged to form an "adder" circuit that can accept two binary numbers and output the sum of their values.
     • AND gates have 2 inputs and one output.
       • OR gates have 2 inputs and one ouput.
         • NOT gates have one input and one output.
           • transistors are electrical components made from semi conductor materials that can act as electrically controlled switches
             • modern CPU's contain over 3 billion transistors,allowing them to perform billions of calculations per second
               • Moore's law famously stated that the number of transistors within an integrated circuit would double every 18 months to 2 years.
                 • computer systems store and process data as binary digits.
