The inner workings of Serial Communication Explained | Part 1

The video tutorial introduces serial communication, explaining its basic principles and various protocols like USB, SPI, and I2C. It delves into USART, a hardware component used in microcontrollers for serial communication, and discusses the differences between synchronous and asynchronous protocols, highlighting the importance of clock signals and baud rates.

What is the primary characteristic of serial communication?

• Sending one bit at a time

• Using parallel data transmission

• Sending multiple bits at a time

• Utilizing wireless signals

Which of the following is a serial communication protocol?

• Wi-Fi

• USB

• Bluetooth

• Ethernet

What does USART stand for?

• Universal Serial Asynchronous Receiver Transmitter

• Universal Synchronous Asynchronous Receiver Transmitter

• Universal Serial Automatic Receiver Transmitter

• Universal Synchronous Automatic Receiver Transmitter

In synchronous communication, what is used to synchronize data transmission?

• Signal strength

• Data packet

• Clock signal

• Baud rate

Why is a baud rate important in asynchronous communication?

• It determines the data packet size

• It synchronizes the clock signals

• It sets the data transmission speed

• It ensures data integrity
