12. Write a brief description of fuzzy logic as compared to Boolean logic and where it might be used (use www.webopedia.com).
    
13. Write a brief description of how Boolean operators are used on internet search engines such as AltaVista, Infoseek, or Yahoo (use www.webopedia.com).
    
14. Use circuit simulation software to
    1. draw a 4-input XOR circuit, and
       
    2. generate a truth table for the circuit.
       The XOR circuit generates a HIGH output when an _____ (even, odd) number of inputs are HIGH.
       
15. Use circuit simulation software to
    1. draw an 6-input NAND circuit, and
    2. generate a truth table for the circuit.
       
16. Use circuit simulation software to
    1. draw a logic circuit for the Boolean expression A' + B' + C' = Y, and
    2. generate a truth table for the circuit.
