i dont have a scanner sorry!

but there were some forms on page no/4 check those out!

airline is real time processing...this is bcz in real time the input, process and output are carried quickly enough to influence or control the source of the input data.(airline booking system affects worldwide)
Patient readings in ICU uses online processing(it does not affect worldwide)......It allows a computer device to be under the immediate control of the main computer.

This is the difference between online and real time processing.
this is what our teacher said about real time and online processing...

i think that these both are swapped
online is booking
real time is the ICU thingy
im not sure, but just checlk

[angell]

yeah its the opposite 4 zara's post:D thats how they make SENSE

[saadmannan]

so can u tell me one thing
do we have to fill the form as it is output form???

[angell]

Yeah u have to fill in the lines or fields that u create!!!

[saadmannan]

is there anything that is included in the syllabus but have not been asked since 2003

[angell]

i have no idea!! im sorry...havent gone through it THAT deeply! Sorry, again!

how an expert system is created?
>Users are interviewed for their requirements
>Data is collected from the experts
>Knowledge base is designed
>Rule base is designed
>Inference engine is designed
>Input screens and output formats are designed
>Testing of the system is done by sample inputs

hoe does it work?
>The input data is compared with the knowledge database
>It(the system) will ask for more questions if required
>It will come to some conclusion.

u 4gt 2 mention that according 2 da rule base da answer is given

A1.no...my sylabus got changed to 0419 and it has routers and hubs....and i tudy from the notes and do pastpapers
A2.yes which evr i get
A3.i hav my skool notes in my ntbk...as said by zara b4 go to tht website...its really good
A4.i hav no idea
A5.yup...bcuz of da new sylabus

try doing the pastpapers from freeexampapers.com

about hubs, Bridge, Gateway, switches and routers


Gateway: It connects networks of difrnt kinds.eg connecting a network of PCs to a mainframe computer.

Bridge: It connects networks of the same type but in different topologies.like ur skool computers different computer labs (LAN networks) are connected together maybe 1 is a star and da other is a ring topology

Router: It connects several networks. It is smart enough 2 pick da right path of communications traffic, If there is a partial failure of the network, a router looks for an alternate route.

Hubs: Connect the stations in the LAN working by broadcasting ie radio signals

Switch: It is like a hub but its more intelligent 2 no the IP addresses.


I hope that this helped..

This is what im doing, seeing questions from the past papers and memorising the mark scheme. It's useful because questions are being repeated

i am absolutely doing da same!!!!!!!   

cuz my teacher sucks

and i am having  tough time with algorithms..........................

r their any techniques to do it
or xxtremely good notes.....plzzzzz inform

u may want 2 have a look at this link its really helpful 4 last minute revisions

Thank u Enia, thats what i was looking for.

Anyone explain the difference between an input and output form, please?

input forms r the ones u c when applying 4 smthng <<<when ur name is written>>>while da output form is da hw da form appears after the data is added the final form


hope this helped

can someone please give the exact definaion of online batch and real time processing

look batch processing is wen data is collected in ""batches"" then processied all in one go when there is no1 working on da computers like in payroll systems

realtime processing is wen small errors arent accepted and may cause a lot of damage like in car manufacturing .. robot arms cannot put the nail in another place as a slight delay will ruin da car shape

online processing is wen there is a slight delay while da data entered is being prcessed like in cinema booking systems....there might b a slight delay as da order would b checked wid other ""booking windows"" to ensure that a seat isnt booked twice


i hope that this helped

[angell]

thank u!!

[Eamyzz]

umm is it really true tht real time affects world wide and like online proceesing doesnt. cuz tht just doesnt make any sense. i mean so what happens if u use real time in ICU in hospitals?

can i have more detailed or technical and the way data is handled in both of the real processing and online processing?

and it would really be great if i have like 2 applications or uses and examples for each of the both processing?

Thanks

It is used in ICUs in hospitals becoz if there is a second delay da patient may die so it wont take tym as sonn as anythng is detected watever action has 2 b taken is taken bt imagine if it was onlyn processing....it will frst read it then detected and there may b a slight delay which may cause a apatient 2 die!!!!!


dd u gt it?

[Eamyzz]

thank u!!

u r wlcm hope it helped
