Document Content and Description Below

Section One With the help of a neat sketch explain the steps and buffers involved when an application writes to a TCP socket. The steps for establishing a TCP socket on the client side are the foll ... owing:  Create a socket using the socket() function;  Connect the socket to the address of the server using the connect() function;  Send and receive data by means of the read() and write() functions.  Close the connection by means of the close() function. The steps involved in establishing a TCP socket on the server side are as follows:  Create a socket with the socket() function;  Bind the socket to an address using the bind() function;  Listen for connections with the listen() function;  Accept a connection with the accept() function system call. This call typically blocks until a client connects with the server.  Send and receive data by means of send() and receive().  Close the connection by means of the close() function. Below is each function described with its importance: 1. The socket() Function It specifies the type of communication protocol (TCP based on IPv4, TCP based on IPv6, UDP). The function is defined as follows: #include <sys/socket.h> int socket (int family, int type, int protocol); Where family specifies the protocol family (AF_INET for the IPv4 protocols), type is a constant described the type of socket (SOCK_STREAM for stream sockets and SOCK_DGRAM for datagram sockets.
