MOSFET symbol

N-channel and P-channel both are Metal oxide field effect transistor ( MOSFET ). It is a four terminal device. MOSFET has four terminal called G called gate, D called drain, S called source and B called base. MOSFET full form source terminal is frequently connected so making it a three-terminal device like a Field effect transistor. It is most commonly used in the analog and digital circuit.
