Anetwork socketis an endpoint of a connection across acomputer network. Today, most communication between computers is based on theInternet Protocol; therefore most network sockets areInternet sockets. More precisely, a socket is ahandle(abstract reference) that a local program can pass to the net...
Local Address is *.65432, which means all available host interfaces that support the address family will be used to accept incoming connections. In this example, socket.AF_INET was used (IPv4) in the call to socket(). You can see this in the Proto column: tcp4. The output above is tr...
Socket programming in Python combines network communication and Python knowledge to build programs that can connect over networks. To help you understand how computer programs chat with each other over the internet, we will discuss the various aspects of socket programming in this post. So, if you...
The previous articles in this series mainly explain the theoretical basis of computer network, but for application layer developers of instant messaging IM, it is actually various API interfaces that deal with computer network. In this article, let's talk about Socket, which is most familiar to ...
computer. If the specified value exceeds the system-maximum length, then the system-maximum length is used instead. No means for discovering the actual backlog value is provided. (The system-maximum value is determined by the SOMAXCONN setting of the TCP network subsystem on the host computer....
A socket is a software endpoint that establishes bidirectional communication between a server program and one or more client programs. The socket associates the server program with a specific hardware port on the machine where it runs so any client program anywhere in the network with a socket ass...
(localhost) and this localhost, most of the time was connected to the Internet. This means, the client and server or sender and receiver programs were run on the same machine. Some examples were run from different paths on the same machine. Some were tested on the private network, running...
Function socket() creates a socket and returns a socket descriptor which can be used in other network commands. The above code will create a socket of : Address Family : AF_INET (this is IP version 4) Type : SOCK_STREAM (this means connection oriented TCP protocol) Protocol : 0 [ or ...
