Protocol ensures reliable delivery
C) Both of above
Answer: Option A TCP
TCP provides reliable stream delivery of data between Internet hosts.
Datagrams are sent by TCP using Internet Protocol, the underlying protocol, and it provides block transmission, or sending a steady stream of datagrams across process ports. TCP offers dependable message delivery in contrast to UDP. Data delivery to a receiving process is prevented by TCP from being corrupted, lost, duplicated, or given out of order. Application programmers are spared from having to incorporate communications security measures into their software thanks to this assurance of transport dependability.
TCP must recover data that is damaged, lost, duplicated, or delivered out of order by the Internet. TCP achieves this reliability by assigning a sequence number to each octet it transmits and requiring a positive acknowledgment (ACK) from the receiving TCP.
