Explain i2c,spi protocols

Question

Accepted Answer

I2C and SPI are communication protocols used to transfer data between devices.

I2C stands for Inter-Integrated Circuit and is a synchronous serial communication protocol used for short-distance communication between devices.
SPI stands for Serial Peripheral Interface and is a synchronous serial communication protocol used for communication between microcontrollers and peripheral devices.
I2C uses a master-slave architecture and supports multiple devices on the same bus, while SPI uses a master-slave architecture and supports only one device at a time.
I2C uses two wires for communication (SCL and SDA), while SPI uses four wires (MOSI, MISO, SCK, and SS).
I2C is slower than SPI, but is more flexible and supports more devices.
SPI is faster than I2C and is commonly used for communication with sensors, displays, and memory devices.
