When using serial transmission, there are three possible techniques for organizing the bits being transferred. Name and describe them.
What will be an ideal response?
Answers will vary. When data is sent using serial transmission, one of the following three techniques is usually used to organize and time the bits being transferred so the data can be reconstructed after it is received.?Synchronous transmission-Data is organized into groups or blocks of data, which are transferred at regular, specified intervals. Because the transmissions are synchronized, both devices know when data can be sent and when it should arrive. Most data transmissions within a computer and over a network are synchronous transmissions.?Asynchronous transmission-Data is sent when it is ready to be sent, without being synchronized. To identify the bits that belong in each byte, a start bit and stop bit are used at the beginning and end of the byte, respectively. This overhead makes asynchronous transmission less efficient than synchronous transmission, and so it is not as widely used as synchronous transmission.?Isochronous transmission-Data is sent when it is ready but all data must be delivered at the time it is needed. For example, when transmitting a video file, the audio data must be received at the proper time in order for it to be played with its corresponding video data. To accomplish this with isochronous transmission, the sending and receiving devices first communicate to determine the bandwidth and other factors needed for the transmission, and then the necessary bandwidth is reserved just for that transmission.?Although all three of these techniques send data one bit at a time, they vary with respect to how the bits are organized for transfer. Please see the section "Data Transmission" for more information.
