Answer:
One advantage of <u>byte-oriented APIs</u> is that all byte of the data sent by the API is retrieved but for <u>APIs with application-defined message boundaries</u>, some bytes of data could be lost in the streaming process.
One disadvantage of <u>byte-oriented APIs</u> is the time it takes to resend a byte increases its propagation delay, while the is an advantage of the <u>APIs with application-defined message boundaries</u> as it does not have to resend any lost bytes of data, making it faster.
Explanation:
Note that byte-oriented APIs uses the TCP socket which resends lost bytes of data and application-defined message boundaries APIs uses the UDP protocol to send data but does not resend if lost.
