[Ravichandran]

Dear students of Block 6 AS computing, welcome to the computing class. I am your facilitator Dr.Ravichandran ( you can call me Dr.Ravi), I will be your course facilitator for AS computing and A2 computing. I will start communicating with you in this discussion forum - where you can start posting your queries and useful resources.

You are highly encouraged to interact with me and also with your peers as the class begins from 30th July 2013.

All the best and keep moving. Do not hesitate to ask and send your queries if you have one.

I need your assistance to solve this problem. Given a string of numbers in sequence order. find the missing numbers."9899100101103104105107108".

[Ravichandran]

No problem

to dr ravi

i won't be around KY this weekend. i'm going back home this week so i'll not be able to use vbnet to test the programming task that dr ravi gave us today since my laptop doesn't have the vbnet thing. but, i'll work the task out except for running the program in vbnet.sorry for troublesome

[Ravichandran]

good attempt Farhan, Keep moving and all the best.

dr Ravi, I've done the programming task on the problem  to generate a list of prime no. from 1-100.

Here I attached the program:

Private Sub Command1_Click()
10 x = x + 1
i = 1
20 If (x / i) = Int(x / i) Then p = p + 1
i = i + 1
If i <= x Then GoTo 20
If p = 2 Then Form1.Print x
If x = 100 Then MsgBox "number of prime number are done": End
p = 0
GoTo 10
End Sub

After the test, I just can't help but feel like making a VB program to find the number of vowels for a given word or sentence... and it works to a certain limit.

V1$ = "a"
V2$ = "e"
V3$ = "i"
V4$ = "o"
V5$ = "u"
A = InputBox("Please input a word or sentence")
B = Len(A)
i = 1
10 C$ = Mid$(A, i, 1)
If C$ = V1$ Then x = x + 1
If C$ = V2$ Then x = x + 1
If C$ = V3$ Then x = x + 1
If C$ = V4$ Then x = x + 1
If C$ = V5$ Then x = x + 1
i = i + 1
If i > B Then MsgBox "The word has" + Str(x) + " vowels": End
GoTo 10

The 1st question of the test is to find the biggest number from each digit of a given 2-digit number. And yes, I made a program for it and it works 100%.

A = InputBox("Please input a 2 digit number")
B = Val(A)
C$ = Left$(B, 1)
C = Val(C$)
D$ = Right$(B, 1)
D = Val(D$)
If C = D Then MsgBox "Both digits are the same": End
If C > D Then MsgBox Str(C) + " is the bigger number": End
MsgBox Str(D) + " is the bigger number": End

Dear Block 6 computing students,

                                                    All the students in the class did well in the first class test. If I am not mistaken one student ended up doing wrong- However, he had made good attempt. Just needs personal attention.

The marks of the students are as follows.

1) Yuganesh 11/15

2) Muhammad Lukman 14/15

3) Suhen N/A

4) Farhan 15/15

5) Megat 8/15

6) Ahmad Ammar 15/15

7) Nabil 10/15

8) Maizatul 9/15

9) muhammad aiman 12/15

10) Syed Muhammad 15

11) ariel  14/15

12) Raid 13/15

13) Muhammad ameet 15/15

I think I have to sit with you guys on a one-to-one basis to discuss on this question paper and how you can get to the next level with better result.

[Ariel Logujin Takom]

Thanks for the result Dr. Looking forward to know what my mistakes are tomorrow. :)

Why is my results N/A ? :(

thanks sir :)

In the first class on theory last week, I learnt about the various types of memory which are RAM, ROM, PROM and EPROM. I was also exposed to the differences of Random Access (floppy, CD) and Sequential Access (magnetic tape, cassette).

[Ariel Logujin Takom]

Finally we start to learn theories! We've learnt about the block diagram of computer and different type of memories of the computers. 

By the way doctor, I just want to ask, why is it that the computer's memory has different characteristics? Some of them are labeled as GDDR5, GDDR3, GDDR4, and with numbers like 1500MHz. What do they mean?
