Socket methods

These are the general socket methods we can use in both clients and servers:

• socket.recv(buflen): This method receives data from the socket. The method argument indicates the maximum amount of data it can receive.
• socket.recvfrom(buflen): This method receives data and the sender's address.
• socket.recv_into(buffer): This method receives data into a buffer.
• socket.recvfrom_into(buffer): This method receives data into a buffer.
• socket.send(bytes): This method sends bytes data to the specified target.
• socket.sendto(data, address): This method sends data to a given address.
• socket.sendall(data): This method sends all the data in the buffer to the socket.
• socket.close(): This method releases the memory and finishes the connection.
