Socket

In recent times, socket has become increasingly relevant in various contexts. What exactly is Socket - Stack Overflow. A socket is an abstraction through which an application may send and receive data,in much the same way as an open file allows an application to read and write data to stable storage. A socket allows an application to "plug in" to the network and communicate with other applications that are also plugged in to the same network.

What is the difference between a port and a socket?. From another angle, an endpoint (socket) is defined by the combination of a network address and a port identifier. Note that address/port does not completely identify a socket (more on this later).

The purpose of ports is to differentiate multiple endpoints on a given network address. You could say that a port is a virtualised endpoint. What is AF_INET in socket programming? AF_INET is an a ddress f amily that is used to designate the type of addresses that your socket can communicate with (in this case, Internet Protocol v4 addresses). When you create a socket, you have to specify its address family, and then you can only use addresses of that type with the socket. The Linux kernel, for example, supports 29 other address families such as UNIX (AF_UNIX) sockets ...

networking - What is a socket? - Unix & Linux Stack Exchange. 113 A socket is a pseudo-file that represents a network connection. Once a socket has been created (identifying the other host and port), writes to that socket are turned into network packets that get sent out, and data received from the network can be read from the socket.

In this context, sockets are similar to pipes. Both look like files to the programs ... Postman : socket hang up - Stack Overflow. I've read a few post regarding socket hang up and it mention about sending a request and there's no response from the server side and probably timeout. Additionally, how do I extend the length of time of the request in Postman Collection Runner? Understanding INADDR_ANY for socket programming.

Note that a socket can be bound to 0.0.0.0, but not port 0, because its a wildcard that makes it give the socket a random ephemeral port, so when you use bind (INADDR_ANY, 0) it binds to 0.0.0.0 and a random ephemeral port. Difference between socket and websocket? Additionally, i'm building web app that needs to communicate with another application using socket connections. This is new territory for me, so want to be sure that sockets are different than websockets. Send/receive data with python socket - Stack Overflow.

Is using the socket library a requirement? The problem description in the body of the question does not say so and it seems that using one of the many established solutions for sending files across a network and that can be controlled programmatically, e.g. in Python, would be fine and avoid re-inventing the wheel.
