I haven't written on here for a few weeks, these two modules (mainly MU123) are keeping me busy, thankfully I am at a place in the module material that I understand. This puts me in a good mood and does not make me want to throw my books, and my calculator out of the window, go out into the garden and stamp on them, pour petrol over them and then carelessly drop a match on them (too far?).

I am enjoying TU129, I have submitted my TMA for it, well, for the networking block anyway. I have one more block to do which is Linux, I started it the other day, but didn't get far as I needed to concentrate on TMA03 for MU123 (which I am still in the middle of doing and it needs to be handed in by the 6th March) I think I have done ok I won't really know until I get the TMA back marked. It was quite a short assignment with only 4 questions. one of which was to work out what the network address is if you have an IPv4 address of 192.100.50.200, with a subnet mask of 255.255.255.240. There was a section in the textbook "Microsoft Windows Networking Essentials" where it told you and showed you how to work that out, it wasn't the easiest thing to get my head around but I think I have done it correctly.

I, as you all know (if anyone has actually found this blog and decided to read it) find mathematics a big headache I really find it hard, it makes me wonder why I'm doing it sometimes. All the other people on this module seems to get exactly what they are doing and understand the key concepts. I, on the other hand really have to study hard to understand it and even then I don't always get it. A prime example is on TMA03. Question 3 asks us to make a variable the subject of the equation! this question is only 5 marks which is nothing with some of the other questions which are 18 to 25 or even 30 marks. For some reason I have cannot get my head around making a variable the subject of the equation I won't write down what the equation is on here as I know what to get accused of some sort of collusion. I can't understand why you would need to change where one of the variables go, so what I mean is if the equation is. 10r=12e/13-21 so if I want to make e the subject of the equation then I have to get e on its own on the left-hand side where 10r is. It is driving me mad, I have looked online and I appear to be doing it right however if I make the variable the subject, I can then substitute a value for let's say, e is now the subject so, e=3 I then substitute that value into the right-hand side of the first equation and whatever the answer is, would be the value for r in the second equation, if I then sub in that value for r the what the answer is should be the original value for e.

It is all very confusing I should be speaking with my tutor tomorrow and hopefully I will have a better understanding and will be able to sort that question out.

I think I have gone on long enough! I'm off to bed.
