Because the Internet address is always unique to a particular host on a network, the socket address for a particular socket on a particular host is unique. Additionally, because each connection is fully specified by the pair of sockets it joins, every connection between Internet hosts is also uniquely identified.
The combination of an IP address and a port number is called a socket address. The client socket address defines the client process uniquely just as the server socket address defines the server process uniquely as shown in Figure.
Also, Where are sockets used?
Sockets are commonly used for client and server interaction. Typical system configuration places the server on one machine, with the clients on other machines. The clients connect to the server, exchange information, and then disconnect. A socket has a typical flow of events.
Hereof, Where is socket programming used?
Socket programs are used to communicate between various processes usually running on different systems. It is mostly used to create a client-server environment. This post provides the various functions used to create the server and client program and an example program.
What is the use of socket and server socket?
Sockets provide the communication mechanism between two computers using TCP. A client program creates a socket on its end of the communication and attempts to connect that socket to a server. When the connection is made, the server creates a socket object on its end of the communication.
Likewise, What is socket and server socket?
Socket programming is a way of connecting two nodes on a network to communicate with each other. One socket (node) listens on a particular port at an IP, while other socket reaches out to the other in order to form a connection. The server forms the listener socket while the client reaches out to the server.

Why are sockets used?
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.
Can processes on the same machine use socket programming?
That’s right, sockets are a way for two processes to communicate regardless of whether it’s over the network or within the same machine.
What type of IPC does socket programming fall under?
The socket type is SOCK_STREAM, which, in the Internet domain, uses Transmission Control Protocol (TCP). — supports a two-way flow of messages. A on a datagram socket may receive messages in a different order from the sequence in which the messages were sent. Record boundaries in the data are preserved.
How socket is created?
A socket is created with no name. A remote process has no way to refer to a socket until an address is bound to the socket. Processes that communicate are connected through addresses. In the Internet family, a connection is composed of local and remote addresses and local and remote ports.
What is IPC socket?
A Unix domain socket or IPC socket (inter-process communication socket) is a data communications endpoint for exchanging data between processes executing on the same host operating system. Valid socket types in the UNIX domain are: SOCK_STREAM (compare to TCP) – for a stream-oriented socket.
What is a socket server?
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.
What is socket address?
A socket address object identifies a socket endpoint for communication. In the case of AF_INET for instance, the socket address object comprises the host address (or interface on the host) and a port number which specifies a particular open socket in a running client or server process.
What is socket address explain with example?
Socket address is the combination of an IP address and port number. Telephone connection is the combination of a phone number and particular extension. Number socket is an internal end point for sending or receiving data at a single node in computer network.
How many sockets does a server have?
65535
What is socket with example?

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.

Does socket programming support multi programming?
You will see that the second client cannot be connected until the first client closes its connection. To allow simultaneous connections we should know multithreaded programming. Here in the following Multithreaded Socket Programming , you can connect more than one client connect to the server and communicate.
