Review for the Final Exam:

Terms and concepts - 
	
	network reference model, process layer, transport layer, network layer, 
	
	datalink layer, address or protocol families, protocols, domains, unix domain,
	
	internet domain, SOCK_STREAM, SOCK_DGRAM, socket descriptor or handle, socket file,

	protocol or domain specific address, IP address, port number, connection-oriented,
	
	connectionless, iterative server, concurrent server, network byte order

	TCP/IP, TCP, UDP, IP, IPv4, IPv6, header, checksum, acknowledgement, sequencing,
	
	three-way handshake, datagram, packet



System calls - 


sockets - socket(), bind(), listen(), accept(), connect(), sendto(), recvfrom()

I do not expect you to remember all the functions we used such as memset(), htonl(), etc
to successfully execute communication in the internet domain, but you much recognize that
such function calls are necessary.

Comprehensive questions:

The second part covers the whole semester by asking questions based on 
programming that you did for the individual assignments.  Make sure that
you remember and understand what you did in each assignment.
