Thanks for the clarification

Hi Chris, I am just wondering when someone will be in the office so we can pickup our midsemester tests, as I don't want to come bother you if you are busy not there. Thanks very much

ANONYMOUS wrote Yes; was discussed in this afternoon's tutorial.

Hello Chris, I was wondering if i could get some hint regarding question 17.Is it ineffective because intruders can easily capture the MAC addresses and also potentially configure their own devices to have that MAC address.

ANONYMOUS wrote Yes, primarily because a node's transmissions can interfere with the transmissions of other nodes that it can't hear. p18 of Lect 5.

ANONYMOUS wrote There'll be 10-12 questions, each worth 1, 2, or 3 marks. No question requires a lengthy answer, instead marks are awarded based on the difficulty of the question and the sophistication of your answer. As some examples, from the list of...

Hello Chris for the question 15 my two reasonings would be regarding the half node problem and half duplex connection where devices can either send or receive data at a time but not both. Do you suggest I am heading the right direction with the answer....

Hello Chris I wanted to know how much marks will be roughly allocated for each questions,I belive that will help meme understand how much points I should be writing in my answers. Thank you.

ANONYMOUS wrote Actually Q5. Both of your points are correct, though 1 2 16 is not really a very low probability (consider 10s of thousands of frames per second), and there is a better answer than the 2 points you've provided. YES (taken care of by o...

Hello Chris, I wanted to check if my reasoning is correct for the following questions 1.The design offers a good balance because 1 in 2 16 is still very low probability and a longer checksum would add to more overhead data addition 9. The network layer...

ANONYMOUS wrote Yes, a good answer. This second part wasn't asked in the question, but also correct. Good luck,

Written by Chris on a previous post on here The implementations of the standard CRC algorithms are certainly not examinable, and Labsheet-1 reinforced this by only treating the CRCs as 'black-boxes', which we called as functions, and they returned a ...

Hi Chris, I would like to request some help with q11 of the practice midsem questions. Can I ask whether my reasoning is correct and whether my response correctly targets your question? Your assistance is greatly appreciated. Q11. Within a sliding windo...

Are CRCs and polynomial codes assessable topics for the mid-sem? Thank you

Please don't refer to old materials, particularly by a number which may change for this year.

13. What is the primary difference between an Ethernet hub and an Ethernet switch? I understand the primary difference between an Ethernet Hub and a Switch is how they handle packets. A Hub will forward the packet to all ports except the port that the...

Doing some revision and would love clarification as to what level of depth we should be understanding Cyclic Redundancy Codes (CRC) for the unit, particularly the upcoming mid sem exam. Noticed the lecture recording mentioned not examinable prior to o...
