I'm going to regret this... are you sure?
Nope, this is just what my prof told me at the uni...
Actually I see that NAND gates are mentioned much more than NOR gates. But searching on Wikipedia (Wikipedia knows it all!) I read:
Wikipedia wrote:NAND and NOR logic gates are the two pillars of logic, in that all other types of Boolean logic gates (i.e., AND, OR, NOT, XOR, XNOR) can be created from a suitable network of just NAND or just NOR gate(s). They can be built from relays or transistors, or any other technology that can create an inverter and a two-input AND or OR gate. Hence the NAND and NOR gates are called the universal gates.
PS: I notice that external links open in the same window... is this wanted? I mean, I'd like external links to open in new windows/tabs, instead of taking the place of the forum...
