Gates(digital electronics)
Gates are basic building block of digital electronics.there are 7 gates used in digital electronics.
They are as follows-
1-AND gate
2-OR gate
3-NOT gate
4-NAND gate
5-NOR gate
6-EX-OR gate
7-EX-NOR gate
Where NAND and NOR called 'Universal Gate'.Because with the help of these two gates we can make all other gates.
Now we will explain each gates with their truth table.here truth table are used for verify it's operation.
1-AND gate
Symbol and truth table of AND gate

2-OR gate

3-NOT gate

4-NAND gate
5-NOR gate

6-EX-OR gate
Where (A ⊕ B)=AB + AB
7-EX-NOR gate
