Question: In a strobe-based destination-initiated data transfer which of the following signals is placed first?
A Data signal
B Acknowledgment signal
C Clock signal
D Request or Strobe signal
Answer: Request or Strobe signal
| Aspect | Description |
| Initiator | Destination (receiver) initiates the process. |
| First Signal | Request or Strobe signal is placed first to signal readiness. |
| Process Flow | · Destination sends a Request/Strobe signal to the source.
· Source, upon receiving the signal, places fresh data on the data bus. · Destination reads the data from the data bus. · The Strobe signal is turned OFF once data is read. |
| Purpose | Coordination of data transfer initiated by the destination. |
| Efficiency | Ensures data transfer only when the destination is ready, reducing data transfer errors. |
| Data Bus Utilization | Data is placed on the data bus only when requested, minimizing bus traffic. |
| Applications | · Interfacing in computer systems
· Synchronous data transfers |
| Benefits | · Minimizes data transmission errors
· Efficient data transfer · Reduced bus traffic |
