Correct if I am wrong: the exams are as follows; we write module 2 on the 13/10/2008 and module 1 on the 16/10/2008 .]]>

Was wondering if anyone could help me out?

Do you guys know if theres a college in JHB that offers all the computer courses of unisa?

Im registered for BSC in IT Management but cant find anyone that offers my degree.

If tried to google but no luck, Boston, Damelin are the colleges that the UNISA help desk suggested but they don't offer it.

Thanks for your time in advance.

Question 1 (Q1)

On the UNISA registration form, there is this question: Ã¢â‚¬Å“May your name, e-mail address and contact numbers be given to fellow students for academic purposes?Ã¢â‚¬?. State the response you gave to this question and briefly explain why you gave that response.

Question 2 (Q2)

Consider the statements:

Ã¢â‚¬Å“Discussing subject-related problems with other students doing the same course, helps me to learn the subject better.

This is especially the case in technical subjects such as those that involve programmingÃ¢â‚¬?.

What is your comment on these statements?

Question 3 (Q3)

Which of the following methods would you prefer to use for collaborative learning with other students? [You may choose more than one; can comment on it/them , and give your experience in using it/them, if any]:

Face-to-face (for example, in or outside a classroom) ; telephone; email; discussion forum (like those on MyUnisa or Osprey); Instant Messaging; Video conferencing; blogs; Wikis; Social networks such as MySpace and Facebook.

You may give your responses on this discussion forum or e-mail them to me at ssemus@unisa.ac.za

Thank you for your contribution.]]>

How did the rest of you do with assignment 1. Personally I was a bit disappointed, I think I under estimated the subject. You really need to focus on these number systems.]]>

1.) If the score is smaller or equal to 100, or bigger or equal to 90, then grade = A (which makes sense)

2.) If the score is smaller or equal to 80, or bigger or equal to 89, then grade = B (which does not make sense)

3.) If the score is smaller or equal to 70, or bigger or equal to 79, then grade = C (which does not make sense)

4.) If the score is smaller or equal to 60, or bigger or equal to 69, then grade = D (which does not make sense)

5.) If the score is smaller or equal to 0, or bigger or equal to 59, then grade = F (which does not make sense)

If you enter this algorithm into a programming language and provide it with sample scores, only scores from 90 to 100 returns a grade.]]>

After doing a bit of research on-line, it's easy to find some information of the types of Cohesion but not of the concept "Global Coupling".

I found this article related to Cohesion useful:

http://en.wikipedia.org/wiki/Cohesion_%28computer_science%29

I also found this one relating to Coupling, but nothing much about "Global Coupling", but you may be able to deduce the answer from this information:

Line reading "as the second operand of the store instruction"

should read "as the first operand of the store instruction"]]>

In the Tutorial letters we see answers with up to 9 decimal places (ie: 1/8 + 1/512 is 0,126953125 [no rounding]), and we will probably see this in the exams as well.

Here are two slow methods that I know of:

1) Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s

Thus, for 4096 it is 244140625 (how do you know that 4096 cannot divide evenly into any 10, 100, 1000 smaller than 1000000000000?)

Now multiply the top and bottom with 244140625 so that you get 244140625/1000000000000, thus the answer is 0,000244140625

2) Use long division (the more practical way for these huge numbers):

You will do a long division of 1.000000000000 by 4096 (treat the decimal point as if it's not there and just put it back again later). With this method at least you can specify the number of decimal places required for a particular answer, should it be specified.

For the sake of time and accuracy these manual calculations might be a problem for me during an exam.

Is there an easier way? (I haven't done any math for more than 12 years and am quite out of practice).

Any ideas or tips?]]>

While it is quite easy to do conversions between hex, decimal, octal and binary. It might become rather difficult without an calculator

I wonder to which extend the Number Systems will be covered in the exam?]]>

I thought I should make this thread for everybody's convenience.

I found an error on Page 21 in Example 2.4. They state 11001 base 2 is = 24 but it is = 25 base 10.

On page 32 under example 2.19 ==> Solution they want the equivalent Hex number form binary number: (1100 1110 0010) witch is = (CE2) base 16.

But in the solution they use:

(100 1110 0010) witch is = (4E2) base 16. They left one bit out in the solution.

Here is a link for a conversion table for Dec, Hex and Binary.

This is really cool is you want to check your answers for the activities in the first part of the Cos113W Tutorial Letter 501.
