The transport layer uses ____ to handle multiplexing and demultiplexing.

To answer this question, we need to understand what multiplexing and demultiplexing are in the context of the transport layer.

Multiplexing refers to the process of combining multiple data streams into a single stream for transmission over a network. This allows multiple applications or processes to share the same network connection.

Demultiplexing, on the other hand, is the process of separating the combined data stream back into its original individual streams at the receiving end.

In the context of the transport layer, the protocol that handles multiplexing and demultiplexing is called the Transmission Control Protocol (TCP). TCP uses port numbers to identify different applications or processes running on a device. When data is sent over a network, TCP adds a header to the data packet that includes the source and destination port numbers. This allows the receiving device to demultiplex the incoming data and deliver it to the correct application or process.

In summary, the transport layer uses the Transmission Control Protocol (TCP) to handle multiplexing and demultiplexing.
