this is for an assignment at my university ok im no computer whiz but ive managed to build myself a chat client using winsock. Now then. we are asked to explain why we used the network protocol we did. All ive done so far is research the minimum i needed to know to complete the assignment which was to build a chat client and that is done. Now hes asking this network question. Im assuming its the advantages and disadvantages of tcp/ip vs udp/ip is that right or are there other protocols that can use. i know mine uses tcp ip cos i have AFNET and SOCK_STREAM. the brief we have isnt very clear. Can you experts sort of decipher this "an apprasial and discussion into the most appropriate network protocols" cheers for any response

Tell them that TCP (connection-oriented or stream-based protocol) is reliable and robust compared to UDP. UDP (connnection-less or message-based protocol) is faster, but is unreliable. UDP is sometime a better protocol for simple messaging.

lets say chat client protocol, if you read his notes the guy gets off on massive words that in a sentece say nothing. im sure if there are people readjg this formum on the same course would all appeal this module as its been VERY poorly taught

so yes chatr client protocol. ok after the tcp / udp discussion what else is there?

the teaching hasn't been great, but it was clear from the lectures that he means tcp / udp... As they were the only two we were supposed to use (and even then he recommended tcp over udp). It's also mentioned in the Criterion Reference grid, though that's even less clear than the assignment brief!

In fact, if you were confused by the wording, you should have brought it up during the seminar sessions for the unit, where either Richardson or Nutter could have sorted it out for you!

Don't mean to dig mate, but it wouldn't have taken much work to get that info before xmas! :D

AP: It was defined during the lecture sessions that we would only be using the Internet Protocol Suite, which was then distilled down to being just TCP / UDP for the transport layer that we were to use...

kuphryn: please don't do his homework for him. The internet really makes it easy to coast through college, but would you want to work with someone who did that?
