Logic gates quiz

Questions on the completion of truth tables and the interpretation of logic networks are quite common in I.T. related qualifications Eg, in electronics or computer science. The five logic gates are AND, OR, NOT, NAND and NOR. In order to understand the theoretical basics you need to know five basic definitions.

This quiz tests the very basics of logic gates. There are no truth tables to fill in or logic networks to interpret. All you need to do is answer questions on basic facts. This quiz should provide a useful starting point assessment for further studies in theoretical logic. Before attempting anything beyond the basics you need to get full marks for this quiz. (This emphasises how elementary this quiz is).
