Detailed explanation-1: -TCP sockets are connection-oriented sockets and hence, require an explicit association between the two socket endpoints. Two connected sockets learn the address of each other during the connection-setup and so they can send data to each other without having to specify the address of the other socket.
Detailed explanation-2: -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. When the address is established, the server waits for clients to request a service.
Detailed explanation-3: -A socket programming interface provides the routines required for interprocess communication between applications, either on the local system or spread in a distributed, TCP/IP based network environment. Once a peer-to-peer connection is established, a socket descriptor is used to uniquely identify the connection.
