Dr. ravi,

based on ariel questions, 

"there are 9 different paper for a season of a year, and there are 2 exam season in a year. For example, like in 2011, there're 9 different papers for May/June, and there're 9 different papers for Oct/Nov. Do we need to answer all of these paper for all 3 years?" or we just need to choose one paper based on our region only?

Maybe someone could post the links for the papers here ? That would be great :D 

[Ariel Logujin Takom]

I gave the link already bro. Just that I'm not sure which one to download :/

http://www.computingrevision.co.uk/

can this site be used for revision? relevant or not?

[Ariel Logujin Takom]

Sir, it seems that there are no question paper from 2013. The one I downloaded (which wrote the number "13" on it) isn't a question paper. :/

[Ariel Logujin Takom]

Oh yeah.. Are we supposed to write the answers on a full-scape paper or should we just type it in MS Word?

[Ariel Logujin Takom]

I found an awesome and easy to understand presentation on Buffers and Interrupts. Happy revising! :D

Sir,

 It is stated that parity block is 99% successful to identify errors in the bytes being sent, BUT in what sort of situation can a two dimensional parity block fail to identify an error ?

[Ariel Logujin Takom]

Yuga, try to refer to this video. Not sure what your question is, but this video explained parity check clearly.

Public u, v, c As Integer
Public a, b As String

Private Sub Command1_Click()

MsgBox "This is a programme to identify the shape and area of a square or rectangle"
a = InputBox("Please enter the length of the shape")
u = Val(a)
b = InputBox("Please enter the height of the shape")
v = Val(b)
If u = v Then Call funcsqr(u, v)
If u <> v Then Call funcrect(u, v)

End Sub

Function funcsqr(ByVal u As Integer, ByVal v As Integer) As Integer
c = u * v
MsgBox "The input data shows that it is a square with area " + Str(c)
End Function


Function funcrect(ByVal u As Integer, ByVal v As Integer) As Integer
c = u * v
MsgBox "The input data shows that it is a rectangle with area " + Str(c)
End Function

The coding I posted is to show how to use the Call function/procedure.
