Question

need help with some doubts on cpp

Answer 1

ready ? :)

Answer 2

Yes :-).

Answer 3

1 min

Answer 4

Okay :P

Answer 5

i have a match the following qn:


A B C

1.dot matrix printer high quality print Optical

2.monitor text editing pixels

3.laser printer Pointing 24 pin

4.mouse resolution
impact 52x
toner

Answer 6

I have doubt in matching B and C

Answer 7

as far as i tried

do matrix impact
monitor resolution pixels
laser printer high quality print
mouse pointing

Answer 8

laser printer is optical i suppose

Answer 9

Mouse > Pointing > Optical (Ever heard of Optical Mouses?)
Laser printer > 52x toner > Higher quality printing (100% sure)
Dot matrix printer > 24 Pin (100% sure)
Monitor > Resolution > Pixels

Optical Mouses:
http://en.wikipedia.org/wiki/Optical_mouse

Answer 10

so i suppose dot matrix goes with impact and text editing is left out

Answer 11

ok?

Answer 12

Hmm.
Dot matrix printing is also called: "impact matrix printing".

As for text editing I'm not sure :S

Answer 13

ok an example for ROM other than BIOS ?

Answer 14

op ?

Answer 15

Hmm.
I'm thinking firmware and some processors.
When talking about ROM you mean "Read Only Memory"?
Honestly I don't know that much about circuits :/

Answer 16

yeh i meant read only memory

qn specially for u >> i am 97 % sure but just confirming

An instruction to CPU consists of an _____________ which tells 'what to do ' and an ________ which refers to 'on what it should be done '.

Answer 17

the exact qn is give any two applications of ROM , I know 1 :used in BIOS

Answer 18

I'm thinking bootstrap.

Answer 19

but doesnt that come under BIOS ?

Answer 20

i am thinking of flash memory now

Answer 21

Okay this is how I see it:
When turning on your computer the CPU reads the address FFFF:0000h.
The address is 16 bytes. This isn't enough for the BIOS...
This address jump or tells the CPU were the actual BIOS is.
After reading the BIOS it writes it to the memory.

Answer 22

i read somewhere flash memory use electrically erasable ROM

Answer 23

what abt the other qn ?

Answer 24

reply ........

Answer 25

op is it lag issue or are u thinking ? :)

Answer 26

I'm thinking.
It's would have been easier if there were choices :/

Answer 27

isnt it opcode and operand ?

Answer 28

Possible but that's too specific.
Maybe it's:

An instruction to CPU consists of an ALU which tells 'what to do ' and an BIOS(memory unit) which refers to 'on what it should be done '.

Answer 29

i think my answer is what they expect in the test

Answer 30

Possible :-).
There's honestly could be multiple answers.It depends on how much you've learned in this subject...

Answer 31

http://en.wikipedia.org/wiki/Opcode i am sure

ok what abt this :

3.A DTP centre works for inputing ,editing and publishing text and images .High quality printers and graphical input devices are required to operate a DTP centre .Considering these factors ,write a technical specification of computer and peripherals required for starting a new DTP centre

Answer 32

.....

Answer 33

I thinking :P.
Okay so is the question asking what would be needed to run the hardware?
I'm not really sure I understand what it's getting at...

Answer 34

its getting at the specifictaion and carries 3 mark ....dont u remember the specification we talked abt for home computing and professional ? But here I think we need modifications

Answer 35

and add ins for DTP facility

Answer 36

Hmm.
Okay let me think.

Answer 37

....................

Answer 38

Okay the peripherals needed for a DTP(Desktop publishing) center are:

Digital Cameras
Printers
Office Equipment
Scanners

\(\text{Computer Systems}:\)
I can't put it exactly what's needed but:
Keyboard, Mouse, Tablet
Memory / Storage
Monitors
Are factor to take into consideration.
Since you are working with images, that can quickly amount to a lot of data.

Most professional designers use a Mac...

Answer 39

i will have to leav for 30 min ..i am typing the rest doubts below :

1) How will you distinguish between field and a record ?

2)match devices with slots

DEVICES SLOTS
1.Display PCI
2.NIC IDE
3.Pen drive AGP
4.Hard Disk Serial

3)cout<<"Result is"<<(mark>=50)?"PASS":"FAIL";

Identify operators ,literals and identifiers in above code segment

4)the ability of a program to act differently depending on situation is known as _______

i think its polymorphism

5)distinguish between
a)Integer I2(I1);
B)Integer I2=I1;
c)I2=I1

Answer 40

There hard drive would normally hold terabytes of data.
So a bigger hard drive is always used, things like 2TB and 3TB are good amounts.

There monitors normally use a higher resolution.
This is for images, and when editing images.

Keyboards:
QWERTY keyboard or Dvorak?
If you are going to editing text you'll need to be fast.

Answer 41

Ok where should i take the specified values from home pc or professional ?

Answer 42

1) How will you distinguish between field and a record ?
A record contains fields...
For example:
If you have a database for a car repair shop.
A record in the database might be for a specific car in your shop.
The record would include fields such as year, make, model, color, and etc.

Answer 43

ok i have to go now ..will try to come back as soon as possible

Answer 44

Okay :-).
I'll keep answering them :D

Answer 45

:D

Answer 46

2) Match devices with slots
DEVICES SLOTS
1.Display PCI
2.NIC IDE
3.Pen drive AGP
4.Hard Disk Serial

Display >> AGP [Accelerated Graphics Port] (AGP is being used less more and more people are going with PCI express now]

NIC (network interface card) >> PCI

Pen drive >> A pen drive is also called a flash drive or more likely a USB. [Universal Serial Bus] So:
Pen drive >> Serial

Hard Disk >> IDE [Ever heard of an IDE hard drive and SATA hard drive?]

Answer 47

doesnt pen drive match to USB ?

Answer 48

Pen drive go with serial.

Answer 49

but i tought USB ports were for pen drives

Answer 50

3)
cout<<"Result is"<<(mark>=50)?"PASS":"FAIL";
Identify operators ,literals and identifiers in above code segment
Operators:
Are like: " +, -, *, /, %, ="
Operators assigns a value to a variable.
The beauty of C++ is it doesn't relay on words! Making it more international :-)
Identifiers:
http://msdn.microsoft.com/en-us/library/565w213d.aspx
Literals:
http://msdn.microsoft.com/en-us/library/c70dax92(v=vs.80).aspx

4)
The ability of a program to act differently depending on situation is known as _______.
I think it's inheritance....

5)
Distinguish between:
a)Integer I2(I1);
B)Integer I2=I1;
c)I2=I1

Uh-oh, lost the connection… Trying to reconnect now.

Answer 51

LOL I got cut off :/
Okay hold on :P I'll type it up again :D

Answer 55

sorry i ran out of medals :P

Answer 56

*bell rings:time to sleep

Answer 57

already? weak... was waiting for op to finish up.

Answer 58

op i have to leav will read ur reply tomorrrow ..thanks in advance

Answer 59

@Opcode is it over?

Answer 60

Wait!
I'm checking something :/
I think I may have mixed it up with some other language :/
But here:
A) Means to take the variable and multiple it's self.
B) Means that the variable is equal to it's self.
C) It's the same as B.

I'm thinking I may have mixed it with LUA :S
Konrad? Anyhelp :3

Answer 61

@KonradZuse i have to wake up early tomorrow ..going o some places

Answer 62

yey !!

Answer 63

it's only 12:30 I just wpoike up :(

Answer 64

its 11 pm here

Answer 65

I'm sure there's a difference between B and C.
I'm just burned :/

Answer 66

@Opcode lols that was not the answer i was looking for ,

i need something like using constructor method calling
,copy constructor, etc

Answer 67

related to that stuff

Answer 68

not common man's language :P

Answer 69

ok bye hav to leav ..bye !

Answer 70

*facepalm*

Answer 71

I realized something... I left this :O
Anyway a copy constructor is when you pass the values of another object to the constructor as arguments.
Here is a simple example:
```
void main
{
integer i1; //Default constructor is called
integer i2(i1);// Copy constructor is called
}
```
Now to answer your question:
```
Distinguish between:
A)Integer I2(I1);
B)Integer I2=I1;
C)I2=I1
```
Both A and B call the copy constructor because "l2" is being created at the time.
Although the difference is B is dynamically initializing the values of object l1 to l2.
For "C" you would need to overload the '=' operator or the compiler would(will) copy the member variable directly.

Sorry for the late reply, I was tipsy yesterday :/

Answer 72

no..and thanks ! today is my last day of preparation ..i got my final tomorrow ..hope u will be here so that i can get cleared of all my doubts !!

Answer 73

So did you understand?
Anyway good luck.

ya i had kind of 70% sure ..just needed to read it thanks

Answer 75

Okay.
