Detailed explanation-1: -Side note: UDP port 152 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 152 makes possible the transmission of a datagram message from one computer to an application running in another computer.
Detailed explanation-2: -I understand the original reasoning behind having 65, 535 ports per IP address: this is the highest number that can be represented by a 16-bit, or 2-byte, number, and it wasn’t conceivable that computers would ever be able to spare more than that for something as trivial as ports, or something like that.
Detailed explanation-3: -The highest TCP port number is 65, 535. The TCP protocol provides 16 bits for the port number, and this is interpreted as an unsigned integer; all values are valid, apart from 0, and so the largest port number is (2^16-1) or 65, 535.
