hello
I have some question:
1. what data type is a port in the C language?
2. what is the compound data type of a socket in the C language?
3. what are the components of the compound type of the socket?
4. what is the correct syntax for making a telnet connection to the sendmail daemon of the mail host mail.cc.army.gov assuming that the daemon is listening to the SMTP well-known port?
5. why is it important, in terms of operating system resources, to close objects such as files and sockets when no longer required?
6. What are the main advantages and disadvantages of basing computer communications protocol on keyworkds and responses in English or other human readable language?
7. what is the purpose of:
> the connect() function call in a communications client.
> the listen() function call in a coomunications server.
> the accept() function call in a communication server.
8. what is the name of the network service that clients use to translate between network addresses and host names, and vise versa?
9. Why doesnt each client keep a copy of the database described in previous qn but relies on special servers for this information?
10. how the PageRank algorithm gives the Google search engine the ability to present pages in an order likely to be of best value to user?
11. how PageRank can be extracted from the connectivity matrix?
Thanks for the Help!
