Which technology allows a Web app to establish a two way communication between client and server?

Which technology allows a Web app to establish a two way communication between client and server?

WebSocket
Let’s start with the basics: WebSocket is a technology that allows a client to establish two-way (“full-duplex”) communication with the server. (A quick review: the client is the application on a user’s computer, and the server is the remote computer that stores the website and associated data).

How do you use a Socketpair?

You can use socketpair only where you create both processes, like so:

1. call socketpair – now you have two socket file descriptors (two ends of a single pipe)
2. call fork – now you have two processes.
3. you now have two processes, each has one file descriptor representing different ends of the same pipe.

What is UNIX socket connection?

Unix sockets are a form of communication between two processes that appears as a file on disk. This file can be used by other programs to establish very fast connections between two or more processes without any network overhead.

What is Af_local?

DESCRIPTION top. The AF_UNIX (also known as AF_LOCAL) socket family is used to communicate between processes on the same machine efficiently. Traditionally, UNIX domain sockets can be either unnamed, or bound to a filesystem pathname (marked as being of type socket).

What is Socketpair used for?

The socketpair() function acquires a pair of sockets of the type specified that are unnamed and connected in the specified domain and using the specified protocol. For socket pairs in the AF_UNIX domain, the protocol must be 0. The domain in which to open the socket.

What is Tipc protocol?

The Transparent Interprocess Communication (TIPC) protocol is designed for use in clustered computer environments. TIPC allows designers to create applications that can communicate quickly and reliably with other applications regardless of their location within the cluster.

What is the value of Af_inet?

AF_INET is an address family 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.

How to communicate with other applications using sockets?

Sockets provide two networked machines with a bidirectional communication channel. One machine will be the server, listening in for connections and the other, the client, attempting to make a connection with the server. An example of this would be when you fetch a web page.

What is the purpose of socketpair in Unix?

socketpair creates an anonymous pair of sockets, usually unix/local sockets, which are only useful for communication between a parent and child process or in other cases where the processes that need to use them can inherit the file descriptors from a common ancestor.

When do you need to use Socket, bind and connect?

If you’re going to do communication between unrelated (in the sense of parentage) processes, you need to use socket, bind, and connect to create a listening socket in one process and create a client socket to connect to it in the other process.

Why are sockets important in one to many connections?

Sockets are just one of the methods for communicating and is useful if you have to implement one-to-many connection. Means, one server process which communicates with many client processes in a request-response fashion. As you are a newbie to IPC, it is understandable that socket addresses and the details involved might look difficult to grasp.
