 Socket Programming using C/C++/Java / python. a. TCP Client, TCP Server b. b. UDP Client, UDP Server. Example: UDP Server using Python import socket   localIP     = &quot;127.0.0.1&quot; localPort   = 20001 bufferSize  = 1024   msgFromServer       = &quot;Hello UDP Client&quot; bytesToSend         = str.encode(msgFromServer)   # Create a datagram socket UDPServerSocket = socket.socket(family=socket.AF_INET, type=socket.SOCK_DGRAM)   # Bind to address and ip UDPServerSocket.bind((localIP, localPort))   print(&quot;UDP server up and listening&quot;)   # Listen for incoming datagrams while(True):     bytesAddressPair = UDPServerSocket.recvfrom(bufferSize)     message = bytesAddressPair[0]     address = bytesAddressPair[1]     clientMsg = &quot;Message from Client:{}&quot;.format(message)     clientIP  = &quot;Client IP Address:{}&quot;.format(address)          print(clientMsg)     print(clientIP)         # Sending a reply to client     UDPServerSoc
