checksum finds integer values of all bytes/packets and of the data stream and adds etc...if the bits change the binary would change and thus the checksum value ? is that how ur thinking Makro

so certainty factors are 0-1 attached to a fact to show the likliness its true. Confidence variables are an attribute whos value is cumulatively added through each certainty factor right...So in a GUI a user can specify how certain they are it is going to rain and make the certainty factor ).7...

expert systems use fuzzy logic tho by using confidence and certainty factors to fire different rules :S oh well lol

i did both papers for these storyboards and each had the layout with the individual screens and just x's where videos were and other stuff to represent each thing in little detail and then a key on the side to say what each represented. each screen was say 4,4 cm so i dont think they will care...

when a forward chaining inference engine cannot reach a conclusion, does it then begin to use backward chaining?

how do we know what its refering to online (web) or online (electronic) :S

where are they stored? im guessing file server?

when you read those questions, i find it hard to distinguish what parts at the actual parts of the system needing to be discusses and what parts are components of another system i.e. HSC 2003 question 26 DSS, we are asked to discuss a company named PMR's system. Their system is developed...

when you get a picture of the diagram (participants, info pro's, purpose..that 1) "describe the following components and their relationship in the context of the scenario...Purpose, participants, data/info, info tech, organising, processing" - has any1 been advised how to answer these (6marks)...

hmm..what text book did you get it out of? because i did animation a while back and i always used path-based as the method of producing the animation..not saving. Each frame would still have to be saved as its own cell/frame and so size would be the same. Maybe it depends on the format because i...

if pathbased is just a way of generating the animation but are stored as separate frames in the final image, how do they require any less processing than cell-based?

is any system that datamines considered to be a DSS as it is getting information to aid in decisions?

for 2001 HSC paper 21 c) could you say that instead of the people at each segment of the parcel sending their data (collected from the barcode scanners) to the database, that infact it is a "download" distributed database system in that the head office computer's database is stored on the...

I think i understand everything now lol :) so cable internet stil uses phone line but just its range of frequencies (above the lower voice) is higher than ADSL and hence faster speeds? i.e. say the medium TP supports 1oo-300Hz (hypothetical ofcourse) - voice = 100-120Hz and ADSL: 120-200...

so i can get a i and i could eventuall do ii from just changing the different sides around as ratio's untill i got the needed equation. When we are doing this ii does every1 just trial and error with the corresponding sides of the similiar triangles untill they end up with the needed equation...

heres another state domain and range y=2root(25-x^2) what different does the 2 make?

woah but u can make x^2 = 4 into x =root4... so confused aye lol

graph y = root(4-x^2) and state range. heres how i have taught myself to do it from answers i) y = o, solve for x to get x=+-2 x = 0 to solve and get y=+-2 so this is a circle right/ but then they take only the top half...is this because of the root? are we meant to know a semi circle is a root...

could you post up an answer to a long answer question from success 1 so we can see the level of depth they wanted...thanks
