logic gates and binary to denary

Question	Answer
There are seven basic logic gates: AND, OR, NOT, NAND, NOR, XOR and XNOR.	Image: ea3df0d6-a815-4eaf-9839-711fe0003502 (image/png)

The NAND gate operates as an AND gate followed by a NOT gate. The output is "false" if both inputs are "true." Otherwise, the output is "true."

Otherwise, the output is "false." Image: ea45fbfa-7fb6-4695-8692-05a0e6837202 (image/jpg)
The XNOR (exclusive-NOR) gate is a combination XOR gate followed by an inverter. Its output is "true" if the inputs are the same, and"false" if the inputs are different.

Its output is "true" if the inputs are the same, and"false" if the inputs are different. Image: 9521ff9c-2952-457f-8ff1-77cccb139fc2 (image/jpg)
Binary to denary	binary is made up of 1 and 0, 1 means true 0 means false. for example
