b)Python supports many networking protocols through libraries such as a socket,SMTP etc and you can also write network programs directly by using TCP/IP or UDP sockets.

TCP VS UDP / CLIENT VS SERVER - PYTHON EXAMPLES
a)Python socket module makes it easy for you to write our own clients and server programs

MULTIPROCESSING IN PYTHON
a)Multiprocessing refers the ability of a system to support more than one processor at the same time. Applications in multiprocessing system are broken to a smaller routines that run independently.The operation system allocates this threads to the processors improving performance of the system
