Sockets are the constructs that allow processes on different machines to communicate through an underlying network, being also possibly used as a way of communicating with other processes in the same host (through Unix sockets). … Whenever new clients land in the second line, the process can then let it come in.
How do sockets work?
Sockets are commonly used for client and server interaction. … A socket has a typical flow of events. In a connection-oriented client-to-server model, the socket on the server process waits for requests from a client. To do this, the server first establishes (binds) an address that clients can use to find the server.
How are sockets implemented?
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.

Why socket is used in Linux?
Sockets allow communication between two different processes on the same or different machines. To be more precise, it’s a way to talk to other computers using standard Unix file descriptors. … This is because commands such as read() and write() work with sockets in the same way they do with files and pipes.
Is socket an API?
The socket API is a collection of socket calls that enable you to perform the following primary communication functions between application programs: Set up and establish connections to other users on the network. Send and receive data to and from other users.
How do I run a client server?
To execute the server, compile the complete server source code and run the executable file. The server application listens on TCP port 27015 for a client to connect. Once a client connects, the server receives data from the client and echoes (sends) the data received back to the client.
What is Sockaddr?
sockaddr is used as the base of a set of address structures that act like a discriminated union, see the Beej guide to networking. You generally look at the sa_family and then cast to the appropriate address family’s specific address structure.
