What is CMOS and MOSFET Types of mosfet and define them How do i know which one is npn and pnp Diff. Between diode and zener diode Bjt and Fet, which one is current control or voltage control Working of mosfet Apart from this some ques. On my project work Define hardware communication protocols Diff. Between SPI and I2C Which one is faster Why we choose SPI over I2C Thank you

Question

Accepted Answer

CMOS stands for Complementary Metal-Oxide-Semiconductor and MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor.

CMOS is a type of technology used in integrated circuits, where both PMOS and NMOS transistors are used.
MOSFET is a type of transistor that is used for amplifying or switching electronic signals.
Types of MOSFET include enhancement mode and depletion mode MOSFETs.
NPN and PNP refer to the type of bipolar junction transistors (BJTs), not MOSFETs.
A diode allows current to flow in one direction only, while a Zener diode allows current to flow in both directions but only above a certain voltage.
BJT is a current-controlled device, while FET is a voltage-controlled device.
SPI (Serial Peripheral Interface) and I2C (Inter-Integrated Circuit) are both communication protocols used for connecting multiple devices in a system.
SPI is generally faster than I2C due to its full-duplex communication.
SPI is chosen over I2C when higher data transfer rates are required or when longer distances need to be covered.
