Khizer sahab and syed 1995 bohot bohto shukria.
Can i have the mark scheme too?

real time transaction involves transaction such as giving money and recieving something on the spot
while real time process control means sensors are involved in maintaining the process...

thank u so much

Q) Describe how computers are used to generate graphics and animation effects for use in
films and arcade games.
A) – animation effects produced by animator using key frames (which define start point and end
point of a movement e.g. open the mouth)
– use of tweening/morphing (differences in appearance between key frames are calculated
using tweening/morphing)
– use of avars (animation variables)
– successive sets of avars control movement of animated character
– adding of surfaces to avars using rendering (realistic image)
– generation of avars using markers on real moving objects …
– … or using joystick to manually produce stick models
– software prevents need to produce hundreds of hand drawn sketches
can nay1 xplain me ths questn acc to mark schem the way it is answwrd????????

khizer shahab & bogus Good luck for the paper Insha Allah tomorrow's paper will be extremely easy and we will get A*

 

[ashiqbal]

guys sorry for being late, was practising past papers
.
can u please answer the question that a few pages before, there was a question of downloading files from computer to mobile phones in two ways, so should we only describe bluetooth, as the answer said? i think there must be another way like connecting mobile phone to computer via USB port, and copying, as two reasons were asked
.
another question:
if there is a description of anything in the marking scheme of a point in brackets, do we have to include the point in brackets to gain marks? and also, can we gain a mark by only writing the description in bracket and not the point
.
third question, should preparing from 2011, 2010, and specimen paper be enough for last minute revision as i had done these papers a long time ago, and was practising old past papers from w07.

 

[ashiqbal]

also, what if we merge two points into one point, and the second point is right and the first one is wrong, will we get the mark??

 

[ashiqbal]

please yaar ignore to naa karo! !

 

[moni]

any guess paper kinda stuff? last minute revision?

Bluetooth was an example given by me, it was not in the marking scheme, the two which i thought were Bluetooth and USB cable, and that's the same which 3 of my freinds thought.

Another could be Sending an email from the Mobile to the PC.

not an examiner, give an example and i might be able to help.

Nothing is enough going through the notebooks might be a lil more important as most theory questions come from that .. i am doing that right now. and Yes I guess if you think that's enough its enough

Now answer my question.


List 3 Differences between Simulation And Virtual Reality.

 

[ashiqbal]

(c) Any one from e.g.:
– (medical) training
– walk throughs (e.g. virtual tours of a house)
– simulators (e.g. flight)
– 3D arcade games
– investigating problems in nuclear/chemical plants
would either walk throughs or either virtual tour of house be enough?

and also for comparison, do we have to give two points from each column for two marks, or one point from each column will gain two marks?
eg: (it is a bit jumbled )
compiler interpreter
– needs to be re-compiled every – translates instructions one
time a change is made at a time ….
– code can be executed on its own – then executes the
instructions immediately
– translates whole code in one go – only finds errors as each
instruction executed
– translates source code into – easier to edit/debug
object code/machine code
– produces error list at end of compilation

What i always say .. screw the marking scheme!

Compiler translates whole program at once / interpreter does it line by line.
Difficult to Debug / Easier to Debug
Needs to compile only when changes are done / Need to interpret everytime regardless of any changes.
Errors shown at the end of compilation of whole program / Errors shown as soon as detected.



ANSWER MY QUESTION PLEASE.

List 3 Differences Between Virtual Reality And Simulation

 

[ashiqbal]

Now answer my question.


List 3 Differences between Simulation And Virtual Reality.

thats not fair! actually virtual reality itself uses simulation!
anyway:
vr:
-3D visual world
-created using computer simulation
-used to perform tasks that are otherwise difficult to perform or hazardous
-eg. medical training, tour inside house

sim:
-studying behavior of system
-using models from computer to predict outcomes
-eg. flight simulation, weather forecast, etc

haha yeah that's the puzzling thing .. its one question which has circulated around but never got answered

btw i like your Signature.

What is the difference between solid state and miniature hard disk drives?

Wiki A type of Web 2.0 site that allows one or more
contributors to create and edit a set of interlinked
web pages.

blogs :short of "web logs" a websites with occasional entries similar to diaries

Podcast: A series of audio or video fi les that is published
on a website and made available as a feed.

bit streams a series of bitsover a time .a live braodcast is distributed as a stream

digital media sharing websites,: resources on internet which holds flash software to view videos and picture and in which tagging can be done for sharing are called digital media sharing websites ( it is what i think pls correct me if i am wrong in it)

tagging is a method of indexinga content of a website to make them easier to find ..

hoped they helped ashiqbal
