What is the main purpose of using start and end bytes in a serial protocol?
easy🧠 Conceptual Q11 of 15
Step-by-Step Solution
Solution:
Step 1: Understand message framing
Start and end bytes are special markers that show where a message begins and ends in a data stream.Step 2: Identify their role in communication
They help the receiver know exactly which bytes belong to one message, avoiding confusion with other data.Final Answer:
To mark the beginning and end of a message -> Option BQuick Check:
Start/end bytes = message boundaries [OK]
Quick Trick: Start/end bytes frame messages clearly [OK]
Common Mistakes:
MISTAKES- Thinking start/end bytes encrypt data
- Confusing start/end bytes with speed control
- Assuming they compress data
