Detailed explanation-1: -A port is a virtual point where network connections start and end. Ports are software-based and managed by a computer’s operating system. Each port is associated with a specific process or service.
Detailed explanation-2: -An IP address has two parts: the network ID, comprising the first three numbers of the address, and a host ID, the fourth number in the address. So on your home network-192.168. 1.1, for example – 192.168. 1 is the network ID, and the final number is the host ID.
Detailed explanation-3: -Because the Internet address is always unique to a particular host on a network, the socket address for a particular socket on a particular host is unique. Additionally, because each connection is fully specified by the pair of sockets it joins, every connection between Internet hosts is also uniquely identified.
