Why it matters
This objective helps connect Communication methods to exam-style questions, flashcards, and revision notes for Communication.
Quick student answer
Which statement correctly defines serial transmission?
Direct answer
Data bits are sent one after another along a single communication path.
Key terms
- Serial transmission: The transmission of data bits one after another along a communication path.
- Asynchronous transmission: A method of transmitting data in separate units, using start and stop bits to identify the beginning and end of each unit.
Common trap
Confusing serial and parallel transmission: Serial transmission sends bits one after another, usually using fewer communication lines. Parallel transmission sends multiple bits simultaneously over separate lines.
