please also state that for calculating a check digit would a method be given in paper ...reply fast !!

Yes .. its always divide by 11 and the digits start from the right side ..


So if the Check digit is

6 5 4 3 2 1
1 5 7 9 5 ?

Similarly

8 7 6 5 4 3 2 1
5 3 2 7 7 2 3 5

Parity Check.

 

[khizer shahab]

no i am asking that a example would be stated in question paper or not bcuz i found an example written in question paper !!!

 

[khizer shahab]

Parity Check.

A* pakka!!!

Yes it will be dude. It has always been that way .. but this year the papers are difficult so they might change stuff

 

[syed1995]

A* pakka!!!

Insha Allah .. Aameen Aap kay muu mein ghee shakkar

differentiate b/w word processor and DTP [2]

 

[syed1995]

Man i can't wait to do the paper ... ! I am just praying to Allah that All of us over here can score an A* or A and nothing below that !!!

btw khizer shahab you did atp or project? and if project how many marks did you get ?

 

[syed1995]

differentiate b/w word processor and DTP [2]

the differences are getting diminished day by day but still ..

DTP has a feature called Master Page, where if you add a logo/clip art to one page it will be copied to all which word processing doesn't have.
Word Processing it is so that usually you work line-by-line/page-by-page .. while in DTP you can put a picture on one page and then work on 5 pages ahead and then compile them later.

I was about to study DTP when you asked it was on word processing.

project 47 marks

 

[syed1995]

project 47 marks

nice !! means you already have 24/25 .. !! now need to score atleast 66/75 !! which is like 88/100

If Cell D2 is to be graded in this way ...

The Grading IF
> 90 then A*
> 80 then A
> 70 then B
> 60 then C
> 50 then D
Below 50 then "U"

what will be the If Condition inside the Cell D2.

this is a tricky question .. bear in mind all those brackets!!

i didn't got this ...~~~~

lemme try

if marks>=90 then grade = A*

like this .....???

Give Atleast Three Differences between
1. High Level Language And Low Level Language
2. Interpreter And Compiler
3. Assembly Language And Machine Code

4. Give 3 Advantages of High Level Language And 3 Disadvantages of Low Level Language.
5. What is the function of INT(X) in pseudocodes. (hint oct/nov 2011)

Answer these 5 questions!!

yea

differences

1)HLL is user friendly while LLL isnt
HLL is written in english while LLL is in binary
HLL requires to be converted but LLL isnt

2)compiler translate all in one go while interpreter line by line
compiler take less time to complete its task while intrprt takes longer time
intrpt doesnt directly produces machine code it first translate into assembly lang(i think so )

3)assembly language is low level language with have some instruction in short word and uses of mnemonics while machine code is binary
assembly lang cant be understand by computer , machine code can
assembly language requires assembler while machine code not

ADVANTAGES OF HLL

1 user friendly 2 easier to remember 3 easier to debug
DIADVANTAGES OF LLL
cant be remember, difficult to debug, not user friendly


5)that was written for" integer of"

uff a difficult one !!!
