Exam 1 - Computer Networks

S2188 over. i hope i can chuck the notes aside and not touch it. Like very no pride.. just aim to pass but it does not matter if i get a 1 or 5 cos it will be reflected as a pass in nus transcipt. anyway this course, our CA and project was pretty high so no need to put much effort inside.. i only studied 7 /13 chapters.. plus if i failed this time , i could easily retake the exam... Such is the favourable system of the European culture.. It was a whole load of acronyms.. need to know what UDP, TCP, SMTP, HTTP stand for... it is interesting to know more abt the internet but when u have to memorise such shit, it is damn duh.. i think i had to memorize abt 35 acronyms and what they meant briefly.. Initially i was damn relaxed the previous day cos' if we spotted calculations questions.. then towards the end of day, we began to panick cos we obtained the mid term past yr sample paper.. it WAS ALL WORDS.. gotta explain n memorize the acronyms.. that was when we started to memorize.. well in the end, wif not enuff slp again, n resigned to my fate, i went to take the exam in s4 at 0900 hrs. The exam was supposed to last 3 hrs but with only 7 qns, most pple left after 1 hr. not like nus, whereby time is always not enuff.. there was plenty of time..

Qn1 : Explain the following acronyms/concepts (6 pts)
i) UDP ii) QoS iii) NAT iv) ASN.1 (v) ARQ (vi)non-repudiance

The following questions 2 - 7 was a mixture conceptual based and memory work. Well , i love open ended questions cos' can crap when i have no idea what it means. Using my linguistic ability to confound Finnish markers when i only have the minimal gist of the idea, hopefully i can pass this time. BY RIGHT should be able to pass ..

DISCLAIMER: cos' blogging is dangerous , i shall say that the following event is purely fictatious

anyway i was a witness of the MCS (Mexican Copying system).. I was strategically placed between Roberto and Javier. and xz was beside javier so that equates to 2 leeches/clients and 2 hosts. i received a couple of copy requests from javier who also had his own cheat sheet in his pocket.. so i was greatly distracted by the occasional rustling of paper when he sneakily takes out to copy. not to mention the constant nudges he gives me and asks me the answer.. then he also tears bits of paper to pass to roberto and he kicks the paper under me.. this symmetric transfer of copy-info continues to n fro with 1- persistance, with me being the 3rd party host.. the handshaking continued throughout the exam and when xz completed his paper, he received an ARQ from client 2. apparently client 2 tore some paper n asked him to write the answers . Both SG hosts were broadcasting their answers and we even let the clients view our papers but the greedy clients wanted more bandwidth and wanted answers on papers. Apparently qn 1 could be easily duplicated but the other answers are too long and crappy so a connection could not be set up. Host 1 then set up connection break down n handed in his paper. Following that, host 2 decided to do the same too.

It makes me feel like yh.. hehe when me, yaya all depended on him for AM quiz... now i know what it feels like... it makes me feel like LWW! i cant imagine ppl depending on MY answers.. haha FYI 3 of my qn 1 answers were wrong so they also wrong!!
