Q3. Explain the operation of diodes
Ans. 
Diodes are electronic components that allow current to flow in one direction only.
• Diodes have two terminals - an anode and a cathode.

• When a diode is forward-biased, it allows current to flow through it.

• When a diode is reverse-biased, it blocks the flow of current.

• Diodes are commonly used in rectifiers, voltage regulators, and signal demodulation.

• Examples of diodes include silicon diodes, Schottky diodes, and light-emit

Q4. Diffrence between switch and amplifier
Ans. 
Switch is used to connect multiple devices in a network and direct data packets, while amplifier is used to increase the strength of a signal.
• Switch is a networking device that operates at the data link layer of the OSI model, while amplifier is an electronic device that increases the amplitude of a signal.

• Switches are used to create networks and connect multiple devices, while amplifiers are used to boost the strength...read more
