Can processes on the same machine use socket programming?
Sockets allow you to exchange information between processes on the same machine or across a network, distribute work to the most efficient machine, and they easily allow access to centralized data. Socket application program interfaces (APIs) are the network standard for TCP/IP.
Is an endpoint for communication between two machines?
Definition: A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.
How to communicate between two different computers with TCP / IP?
Now, on each example I’ve gone through, they’ve always placed the “server side program” on the same computer on which the “client side program” was, and of course the IP set was either 127.0.0.1 , or simply “localhost”. Now, my question is: how do I get to communicate the two programs if one is on a computer, and one on another?
How to communicate between two different Java programs?
I’ve been studying how to use sockets to make two java programs communicate. Now, on each example I’ve gone through, they’ve always placed the “server side program” on the same computer on which the “client side program” was, and of course the IP set was either 127.0.0.1 , or simply “localhost”.
Can two programs Listen on the same socket?
Yes (for TCP) you can have two programs listen on the same socket, if the programs are designed to do so. When the socket is created by the first program, make sure the SO_REUSEADDR option is set on the socket before you bind (). However, this may not be what you want.
Why is it possible to use the same port on TCP and UDP?
IP uses the “protocol” to pass to the next layer such as TCP and UDP though there are others. TCP and UDP each seperately differentiate connections based on the remaining 4 items. It’s possible to create other protocols on top of IP that use completely different (perhaps port-less) differentiation mechanisms.
