What is the difference between connecting to RDBMS using ODBC and native drivers?
Read Best Answer
Editorial / Best Answer
Answered by: David W.
- Mar 29th, 2006
ODBC is an open standard for software providers to follow when creating an intermidate layer between the database and the application using the database. Having "open standards" usually means that different applications can write their code the same way no matter which database they are using, as long as that database comes with an ODBC driver.In contrast, native drivers are built with one specific database in mind. Thus, applications written to use the native driver will only work with one particular database. You will lose flexibility in your code's ability to switch database vendors, but you might gain performance enhancements due to the fact that the driver is custom made for the database and may be able to take advantage of an "insider's view" of the database software.

Data Modelling is designing of the data content and structure of the database.
The data model documents the structure of and interrelationships between the data - it is presented as a combination of simple diagrams and written definitions and is independent of any DBMS software or hardware considerations.

What is the difference between collision domain and broad cast domain?

A collision domain is a logical area in a computer network where data packets can "collide" with one another, in particular in the Ethernet networking protocol. The more collisions in a network the less efficient it is.
A broadcast domain is a logical area in a computer network where any computer connected to the computer network can directly transmit to any other in the domain without having to go through a routing device.

How do you implement "Queue" functionality by using "2 Stacks"
Read Best Answer
Editorial / Best Answer
saradalincoln- Member Since Jun-2007 | Jul 17th, 2007
hi,
1. Take 2 empty stacks.
2. Fill the 1st stack with some items (eg: input 100, 101, 102, 103)
3. Now read the items from 1st stack in LIFO order and write to 2nd stack.
(By this the 2nd stack will get the items in the order .. 103, 102, 101, 100)
4. Now read the items from 2nd stack in LIFO order i.e. the output will be
100, 101, 102, 103.
(this is the queue order FIFO with respect to the actual items entered in 1st
stack.)

Why contructors does not supports visual functions?

Editorial / Best Answer
Sandhya.Kishan- Member Since Mar-2012 | Apr 17th, 2012
Constructor does not support virtual functions because we need an object to invoke a virtual method in the first place and more over constructors are used to initializing objects,which is a static type.Virtual functions are invoked on the dynamic type of the object,hence the object may not be properly initialized when a constructor call is made.Since the derived part of the object would not be initialized during the execution of base class constructor,hence calling any virtual method from base class constructor does not work well.

Two-Dimensional Arrays
A Two-dimensional array X (7,9) is stored linearly column-wise in a computer's memory. Each element requires 8 bytes for storage of the value. If the first byte address of X (1,1) is 3000, what would be the last byte address of X (2,3)?

Thinks of a situation where you need to do some work just once in a function irrespective of how many times that function is invoked then u can have a static variable which will keep a track of it. eg int main () { static int once = 0; if (!once) { once++; /*code need to be executed once*/ } /*reset of the code*/ }

Define Raster and Vector Data.
Define raster and vector data. Explain what is the difference between raster and vector data?
Read Best Answer
Editorial / Best Answer
Sandhya.Kishan- Member Since Mar-2012 | Jul 4th, 2012
Raster data is a set of horizontal lines composed of individual pixels, used to form an image on a CRT or other screen.Raster data makes use of matrix of square areas to define where features are located. These squares are typically of uniform size, and their size determines the detail that can be maintained in the dataset.Raster data represent square areas, they describe interiors rather than boundaries. Vector data use X and Y coordinates to define the locations of points, lines, and areas (polygons) that correspond to map features, vector data tend to define centers and edges of features.They are excellent for capturing and storing spatial details

There will be a lot of changes in fact. First of all, all the variables the function was suing needs to be pushed into the stack. (we need all these variables when we return from the other function). The Program counter will be pushed to stack too... (When the "return" of second function occurs we should know where to 'return' to)These are the basics which are bound to happen when a function calls another.

What is virtual Memory under Linux?
Read Best Answer
Editorial / Best Answer
Answered by: Hitesh
- Jan 3rd, 2007
Linux supports virtual memory, that is, using a disk as an extension of RAM so that the effective size of usable memory grows correspondingly. The kernel will write the contents of a currently unused block of memory to the hard disk so that the memory can be used for another purpose. When the original contents are needed again, they are read back into memory. This is all made completely transparent to the user; programs running under Linux only see the larger amount of memory available and don't notice that parts of them reside on the disk from time to time. Of course, reading and writing the hard disk is slower (on the order of a thousand times slower) than using real memory, so the programs don't run as fast. The part of the hard disk that is used as virtual memory is called the swap space
