Final answer:
EFB stands for Error Feedback Block, TFB stands for Transmit Feedback Block, and EFR stands for Echo Frame Request. These terms are used in telecommunications and networking.
Step-by-step explanation:
In computing, EFB stands for Error Feedback Block, TFB stands for Transmit Feedback Block, and EFR stands for Echo Frame Request. These terms are used in telecommunications and networking.
The Error Feedback Block (EFB) is used to report errors or failures in data transmission. It allows the receiving device to inform the sending device that errors have been detected, triggering retransmission of the data. This helps ensure accurate and reliable communication.
The Transmit Feedback Block (TFB) is used to provide feedback to the sender about successful or failed data transmissions. It allows the sender to know whether the data was successfully received by the intended recipient or if there were any transmission errors.
The Echo Frame Request (EFR) is a request sent by a device to test the quality and integrity of the communication channel. The device sends a frame and expects it to be echoed back by the receiving device. If the echoed frame is received correctly, it confirms that the channel is working properly.
