Answer B. Socket
A port number identifies some service running on a computer.
IP address identifies computers in a network.
The socket is a pair which has an IP address and port number.
So, each service in each computer connected to a network can be identified uniquely through a socket.
The object that effects a connection between and individual client and a server is a(n) A...
Remember client-server connection implementation:A1 socket = socket(AF_INET, SOCK_STREAM)2 socket.bind((ip,portNumber_))3 socket.connect((name, portNumber))B1 socket = socket(AF_INET, SOCK_STREAM)2 socket.bind((localIP, portNumber))3 socket.listen(3)a. What type of transport layer protocol is this?b. What is section A ?c. What is section B ?d. Is it possible to remove a line of code from any section? Please give explanation.e. In section B line 3, what is the meaning of “listen(3)”
With the aid of diagram, describe the connection-oriented socket process between server and client. b) Explain what are the difference between stream socket and datagram socket? Give an example for each of them.?
You are to write a Java program using the following instructions to build a bank-ATM server system with sockets. A bank holds accounts that can have deposits, withdrawals, or retrievals of balance. The bank server provides the account for transactions when a client uses and ATM machine. The ATM asks for the type of transaction and the amount (if needed), then creates a socket connection to the bank to send the transaction for processing. The bank performs the transaction on...
For Unix in a C/C++ environment echoServer and echoClient are provided below In this lab, we will modifiy echoServer.c and echoClient.c programs (for the server's port# not fixed). (1) Modify echoServer.c program to take one argument (a port number) to be used for its listening port when it starts. (2) Modify echoClient.c program to take two arguments (server's IP address and Port number) to be used for its connection. (3) Find a port free for the server using netstat (see...
Modify the socket-based date server below so that the server services each client request in a separate thread. import java.net.*; import java.io.*; public class DateClient { public static void main(String[] args) { try { /* make connection to server socket */ Socket sock = new Socket(“127.0.0.1”,6013); InputStream in = sock.getInputStream(); BufferedReader bin = new BufferedReader(new InputStreamReader(in)); /* read the date from the socket */ String line; while ( (line = bin.readLine()) != null) System.out.println(line); /* close the socket connection*/ sock.close(); ...
I have to modify a server program and chat program to work as the following instructions but I am completely clueless as to where to start. I'd appreciate any help on how to atleast get started. This must be done in java. Diffie-Hellman Two parties use a key agreement protocol to generate identical secret keys for encryption without ever having to transmit the secret key. The protocol works by both parties agreeing on a set of values (a) and (q)....
Using the programming language of your choice, write a client application which: Connects to a network service, then Asks for version information, then Receives the response, then Disconnects and Prints out the response. Detail: The program will take no input from the user. When your program is executed, it should connect to IP address 64.183.98.170 on port 3800. Upon successful connection, send the string: version\n where \n is an end of line marker. The server will respond with a string...

14. (10 Points) Suppose Proces A running on Host Process B running on Host Y vi running on Host Z is communicating with Process via a TCP connection. Let x, y, and z be the IP addresses o and Host Z, respectively. Assume the port number o the port number of Process B is 464 26145, and the port number of Process D is 80. a. What are the identifiers of the socket associated with Process B when it is...
