You can have a total of 65,535 TCP Ports and another 65,535 UDP ports. When a program on your computer sends or receives data over the Internet it sends that data to an ip address and a specific port on the remote computer, and receives the data on a usually random port on its own computer.
Also asked, why are there 65535 ports?
TCP, UDP and perhaps other IP services, use ports for discreet communication between client and server processes among hosts using an IP network. For TCP and UDP, these are the first 32 bits immediately following the IP header; they begin at the 192nd bit. A 16 bit number has values between 0 and 65535.
Furthermore, how many ports are there in laptop? In the context of networking, each network interface (a computer may have several interfaces) can have 65536 TCP ports and the same number of UDP ports.
Just so, how do I find the ports on my computer?
- Open Command Prompt by typing “Cmd” in the search box.
- Enter the “ipconfig” command.
