AND and OR logic gate schematics

[izdane]

Could some one please give me a schematic for a AND or OR logic gate. All I can find are their symbols which doesn't really help.

This should help, thats not the way all of them work, but that is a way to do it.

Why do you need this? (this may better help us answer the question)
