9.1.1 Serial and parallel transmission

• What is serial transmission?

  Data bits sent sequentially
• Serial transmission requires fewer wires than parallel transmission.
• Serial transmission has a slower transmission speed compared to parallel transmission.
• Why is serial transmission effective over long distances?

  Timing is less critical
• Serial transmission is commonly used in USB connections.
• What are the two main types of serial transmission?

  Synchronous and asynchronous
• Synchronous transmission uses a shared timing clock to synchronize data.
• Asynchronous transmission uses start and stop bits to frame each byte.
• In which applications is asynchronous transmission often used?

  Keyboards and modems
• Serial transmission requires fewer wires than parallel transmission.
• What is the speed comparison between serial and parallel transmission?

  Lower for serial
• Parallel transmission is effective over long distances.

  False
• Synchronous transmission relies on a shared timing clock for synchronization.
• Which bit signals the beginning of a byte in asynchronous transmission?

  Start bit
• In asynchronous transmission, each byte is framed by a start bit and a stop bit.
• Synchronous transmission requires a constant data stream without gaps.
• Provide an example where synchronous transmission is used.

  Video streaming
• Parallel transmission sends multiple bits simultaneously over several wires.
• What is a disadvantage of parallel transmission over long distances?

  Timing skew
• In which internal computer components is parallel transmission commonly used?

  Hard drives and RAM
• Parallel transmission offers higher speed but requires more complex wiring than serial transmission.
• What is parallel transmission?

  Multiple bits over multiple wires
• Parallel transmission offers high-speed data transfer.
• Timing skew in parallel transmission makes it less effective over long distances
• Where is parallel transmission commonly used?

  Internal computer components
• Serial transmission sends bits one by one over a single wire.
• Serial transmission has a lower speed compared to parallel transmission.
• What is the primary difference between serial and parallel transmission in terms of wiring?

  Single wire vs multiple wires
• Serial transmission is effective over long distances because timing is less critical.
• What are the two methods of serial transmission?

  Synchronous and asynchronous
• Asynchronous transmission uses start and stop bits for synchronization.
• Video streaming is an example of synchronous serial transmission.
• Why is parallel transmission less effective over long distances?

  Timing skew
• Parallel transmission sends multiple bits simultaneously over several wires.
• Parallel transmission uses multiple wires, whereas serial transmission uses only one.
• What are the key differences between serial and parallel transmission in terms of bit transmission?

  One by one vs simultaneously
• Serial transmission requires fewer wires, reducing cost and complexity.
• Serial transmission has lower speed compared to parallel transmission.
• What are some examples of serial transmission use cases?

  USB and Ethernet networks
• Parallel transmission offers high-speed data transfer because multiple bits are sent simultaneously.
