Detailed explanation-1: -TCP provides reliable stream delivery of data between Internet hosts. Like UDP, TCP uses Internet Protocol, the underlying protocol, to transport datagrams, and supports the block transmission of a continuous stream of datagrams between process ports. Unlike UDP, TCP provides reliable message delivery.
Detailed explanation-2: -Transmission Control Protocol (TCP) is a standard that defines how to establish and maintain a network conversation by which applications can exchange data. TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other.
Detailed explanation-3: -Transmission Control Protocol (TCP) is considered ‘reliable’ is that the protocol itself checks to see if everything that was transmitted was delivered at the receiving end (it may not have been due to packet loss).
