Explain the working of an 'and' gate with a truth table.

• The 'and' gate produces a high output (1) only if all the inputs are low (0). If any of the inputs is high (1), the output is low (0).

• The 'and' gate produces a high output (1) if any of the inputs are high (1). If all the inputs are low (0), the output is low (0).

• The 'and' gate produces a low output (0) only if all the inputs are low (0). If any of the inputs is high (1), the output is high (1).

• The 'and' gate produces a high output (1) only if all the inputs are high (1). If any of the inputs is low (0), the output is low (0).

Explain the working of an 'or' gate with a truth table.

• At least one of the inputs is true

• None of the inputs are true

• The output is always false

• Both inputs are true
