What is a serial protocol in communication?
A serial protocol is a set of rules that controls how data is sent one bit at a time over a single wire or channel between devices.

Why do we use start and stop bits in serial communication?
Start and stop bits tell the receiver when a data packet begins and ends, helping to keep data synchronized and avoid confusion.

What is baud rate in serial communication?
Baud rate is the speed of data transfer, showing how many bits are sent per second over the serial line.

How does parity help in serial protocol design?
Parity adds a simple error check by counting bits to see if the number of 1s is even or odd, helping detect mistakes in data.

What is the role of a checksum in a serial protocol?
A checksum is a number calculated from the data that helps the receiver verify if the data arrived correctly without errors.

What does a start bit indicate in serial communication?
✗ Incorrect
The start bit signals the receiver that a new data packet is starting.
Which of these defines the speed of bits sent per second in serial communication?
✗ Incorrect
Baud rate is the measure of bits transmitted per second.
What is the main purpose of a stop bit?
✗ Incorrect
Stop bits mark the end of a data packet to keep communication clear.
How does parity help in serial communication?
✗ Incorrect
Parity checks if the number of 1 bits is even or odd to find errors.
What does a checksum do in a serial protocol?
✗ Incorrect
A checksum helps verify that data was received correctly without errors.
