State the difference between Byte streams and message
Byte streams and message are different. In a message stream, network keeps track of the message boundaries. In a byte stream, it does not keep tracks. For instance, suppose a process writes 1024 bytes to the connection and then a little later writes another 1024 bytes. The receiver then reads 2048 bytes.
With the message stream, receiver will get two messages each of 1024 each. With a byte stream, message boundaries do not count and receiver will get the full 2048 bytes as a single unit. The fact that there were originally two separate messages is lost.
