  1. For this quesiton I chose A, the only other option which makes sense is D. D has some truth in it because it says interpreters will find errors in source code befo they are run but the second one im unsure because when i compile a program with syntax error it throws and error, but it says execute source code which is misleading. Im really stuck on choosing between the both A seems so right I can see what is wrong with B and C but cant see what is wrong with answer D. can anyone help me and tell me if im correct or completely wrong.
  2. I previously posted this in the Computer science section however, as the admin said its more relevant to this post. The question is regarding Huffman coding, The answer I chose Was A because according to huffman coding you have to sort the frequency by lowest to highest and then take the two lowest out as leaves at the bottom of the tree and start with the highest frequency at top, the one that resembles this description is A, as H & N have the lowest in frequency. I have chosen A as the answer am I correct or is this wrong?
  3. Thank you very much solving it =] the way u explained it was so much better than I learnt this year made so much more sense about think of the gates when inverted sometimes tehy turn into simple ands. =]
  4. thank you I think I get it now..let me explain the answer is A btw am I right? becausee.. (A AND B) or Not (not A OR not B) the OR in the middle of the equation allows both sides to allow the 1 to be the output for every scnerio for example if A and B do not fulfill the requirement then the other part of the equation allow the scnerio ot be complete because the OR requires either the left or right to fulfill the boolean criteria thats why all the outputs are 1. all this time i have been thinking that the plus sign means that both have to satisfy the criteria in order to deliver the 1. So in this case A is the right answer because the equation either left or right always allows use to get an output of 1? Am i correct?
  5. Hi, ive moved this topic here as one of the admins said it belond here. Does anyone have any good resource on how to convert An analogue audio signal to a digital one. I came across this question and have no idea on how to solve it, just the input that one member from this forums which was much appreciated =]. Q. An analogue audio signal is converted to digital using sampling rate of 200hz with each sample using one of 64 different levels. How many bits are needed to encode ten seconds of sound(you should ignore the memory requirements for any metadata in your calculations)? Answers: a. 1,280 bits b. 5,000 bits c. 12,000 bits d. 128,000 bits so the calculation i did was 200 * 10 *64 = 128,000, which the answer is D. However, I was wondering if there is any other way to work the answer out. Thanks
  6. As humans we interact with software and hardware, however there is another layer which im trying to understand at the momment. for example: our interaction which one seems more correct. The question is : Which way do software, hardware and people work together. Now I have narrowed it down to two answers and my answer is C however, im unsure because there is another option and I will explain my thinking behind it. answer I chose was: C Users --> Application --> Operating System -- > Physical machine ( users interact with application which interact with OS which interact with Physical machine) another option was B Users --> Operating System --> Application --> Physical machines. I chose C because applications are installed on operating systems which allow us to interact with the computer. However, B suggests that we use the operating system to interact with applications this is what is confusing me because it is true that we need an operating system to interact with applications. My question is do we interact with the Operating system or Applications.
  7. if its not A and B or not(notA or notB) then it would just return 0 unless both are 1 or both are 0?
  8. from what I have understood the answer I came up with was D because : the inverse of A or B is is only shown in truth table D. for example whenever a or b is 1 it outputs 1, and when it is 0 it remains 0. Am I correct in thinking that or Am i still reading the equation wrong. Im reading the equations not(a and B) + not(a or b)
  9. yeah omg that is so stupid I seriously was thinking that E is a different client so it was confusing me so much so the answer has to be D and assuming that A and D are the same client. Because there is no way that object c is a firewal lol as answer B suggests
  10. thanks for clearing that up what about the plus sign in the middle and the question mark because thats what is really confusing me
  11. I chose D for this question because Im sure that object C is a database which is on the Server which is B and A is the client and B is another client... whats confusing me is that should the data return back to the client that requested the data why is the data requested by A going to E ? if anyone could help clarify this example I would appreciate it thank you, please let me know if im incorrect.
  12. For the following question I chose C as the answer. I tried using just clear logic. For example. Users --> applications --> operating system --> physical machine. as the interaction, any thought if I am wrong the only one that comes close to looking a bit understandable is B but im not sure if we interact with applications or the operating system...anyone can clarify the justification for the answer for me would appreciate it
  13. =] thank you for leading me to the right path your welcome =]
  14. B is incorrect :S, after seeing the article the only clear answer seems to be C because data is data(input) cpu instructions(procecessing) and this process is backwards and forwrds....
  15. For this question I chose B as the von neuman architecture talks about input process output... so Im thinking B represents this proces ass B. data <--> cpu <-->intstructuions The only one that bothers me is D because im not sure on how t say why it is wrong. Firstly, my understanding of D is data provided by the user and sent to the CPU through instructions but then again it goes against the Von Neuman architecture.. any thoughts?
