• Symbol: The symbol for an AND gate looks like this: AND Gate Symbol
• Input Signals: An AND gate takes two or more input signals, usually labeled as A and B, and sometimes more inputs like C, D, etc.
• Output Signal: The output of an AND gate is high (1) only when all of its input signals are high (1). Otherwise, the output is low (0).

• Symbol: The symbol for a NOT gate looks like this: NOT Gate Symbol
• Input Signal: A NOT gate has a single input signal, often labeled as A.
• Output Signal: The NOT gate inverts its input signal. If the input is high (1), the output will be low (0), and vice versa.

• Symbol: The symbol for an OR gate looks like this: OR Gate Symbol
• Input Signals: An OR gate takes two or more input signals, usually labeled as A and B, and sometimes additional inputs.
• Output Signal: The output of an OR gate is high (1) if any of its input signals are high (1). It's only low (0) when all input signals are low.
