Dell's Laptop

Dell has gone all Mad. I had received a mail from them and they were giving this laptop at a dirt cheap price of about 39900/- and looking at the configuration this is pretty impressive. http://www.dell.com/content/products/productdetails.aspx/inspnnb_1525?c=us&l=en&s=dhs&cs=19 . I evaluated my friend's Dell Laptop and they are extremely crispy more than all the Laptops in this section. I just love this Lappy. The way things are going maybe after some days we can get one lappy free with another....[:D] just a comment. But the computer was giving a Crisp performance thanks to its 2GB RAM. But some of the excellent features are

• It is extremely light
• An LED charger indicates the Battey performance
• Dell has much more Crisp user oriented Business programming Computer.
• GSM SIM Card identification/pairing...

WINDOWS VISTA

Hi Everybody,

I am updating the Blog after a long long time. Well I have something new for you all. I am going to talk about Microsoft's new Operating System, the long awaited and hugely hyped Windows Vista...

Well I somehow bumped across Windows Vista Ultimate Edition a few days back and I was just checking out some of the features of Windows Vista...As you must have already seen the exciting Screenshot of this O.S and must be thrilled but here I will give you some good and bad points of Vista as well..They are as follows

GOOD POINTS:

a)This latest Edition of the OS has a tremendous look and feel. The Aero/Glass interface simply rocks and is very Sofisticated as well. The Black Taskbar and the awesome Picture Quality of the Wallpapers suites today computing aptly. Essentially the Glass interface adds value to the design and the look..Thus this OS is very aptly suited for Laptops since this supports Vibrant Technology Screens and the Resolution is very good even in Laptops TFT Monitors.

b)This OS has a terrific sound Quality and the noise Reduction is simply Great. Thus the Music and the Videos Experience is far far better than that of XP...

c)The OS has some good Features like Skipping or ignoring portions which are corrupted. This also works in case of Copying and does not stop due to Cyclic Redundancy Errors!!!

Mathmatical Precision of Numbers

Hey Everybody check this out.....
I am going to talk about Mathematical Precision of Computer Programming Languages in this Article...I saw some Articles where there were some people who wanted to know the Factorial of 100...So I solved the problem in 3 languages to check the Mathematical Precision and this is what I got as Result.....

/*---------------------------Program in C--------------------------*/
#include
#include
void main(void)
{
double num,fact,i;clrscr(); fact=1.00;
printf("\n\n\tPlease Enter the Number: ");
scanf("%lf",&num);
for(i=1;i<=num;i++)
fact=fact*i;
printf("\aThe Number is: %lf ",fact); getch();
}/*-----------------------End of Main-------------------------*/

OUTPUT: 9.33621544394410220000000000000000e+157

/*-------------------PROGRAM IN JAVA--------------------------------*/
import java.io.*;
class Factorial{
public static void main(String args[]) {
double a=0,i,f=1;
try {
System.out.print("\n\n\tPlease Enter the Number: ");
DataInputStream d=new DataInputStream(System.in);
a=Integer.parseInt(d.readLine());
}catch(Exception e) { }
for(i=a;i>0;i--)
f*=i;
System.out.println("The Factorial of "+a+" is "+f);
}
}/*-----------------------End of Class Factorial----------------------------*/

OUTPUT: 9.336215443944118E157

//------------------------PROGRAM IN C#.NET--------------------------//

using.System.Data;
class Fact
{
private double num,fact,i;
public Fact( )
{
this.fact=1;
}
public void input( ){
Console.Write("\n\tPlease Enter the Number upto which you want to See: ");
num=int.Parse(Console.ReadLine( ));
}
public void calculate( ){
for(i=1;i<=num;i++)
fact*=i;
Console.Write("\n\tThe Factorial of"+num+" is :"+fact);
}
public static void main(String [] args) {
Fact fac=new Fact ( );
fac.input( );
fac.calculate( );
}
}/*--------------------------End of C# Program-------------------------------*/

OUTPUT: 9.336215443944102E+157

//-----------------------------------------------------------------//

Comments: So you see from the above examples that the Languages are getting Richer and more Advanced the Mathematical Precision decreases. The Modern Languages are meant for all Practical Purposes and real Life problem Solving so they are not very Precise but they deal with the Data more Effectively...............

The Wonder that Wi- Fi is!!!!!

Hi friends, This is the first time that I had a practically experienced the wonder of Wi-Fi systems. It so happens, that one of my friends have set up a Wi-Fi Spot in their Home using a Broad Band Modem, a Wireless router, three Desktops and a Laptop. He has 2 Computers on Windows and 2 on Linux, that too different versions, one running on Fedora Core and the other on Knoppix Linux. It's just marvelous how these things connect to each other all having different OS. Can U believe it, I was accessing Internet from Linux and simultaneously sharing application and files with my Friends over the LAN. I could even share data with the Laptop & that too Wirelessly..Stop Marvelling and Start Feelin Well if you want to know more about Wi-Fi and want this kinda setup in your Home then follow the link http://www.geocities.com/sudipnandy2008. You may also mail him at sudipnandy@gmail.com . Well if you want to learn more than what he knows then you better take a free networking course online or spend money into some round the corner Training Centre ....

Technical Troubles Concerning VOIP

Hi I welcome you all Tech Savvy people:
Many of you by now must have used VOIP to talk to relatives in foreign countries but this what I got unearthing a Magazine about the security Problems.
VOIP is used by many portals and claiming to give you access Voice over Internet absolutely free or at Dirt cheap rates thus making it very easy for people to talk to relatives and Friends in other nations. Well this is where the problem lies.

Explanation:
The VOIP's work in an enviorenment where Terminal computers called as Nodes access the System via low level local host Servers and this access is called Network Protection Access(NPA) which was absolutely safe just a few years back. But the sudden booming demands for faster and Secure Network Access by various sources like
Wired Networks over Intranet, Remote Networks over Internet
Wireless Networks all require safe and sound network access. What the customer doesn't realise is the trouble which an IT company has to undergo to keep Hackers and Viruses at Bay for the Benefit of Users. Potentially every node accessing the Network is a Platform as well as a System Bug which can anytime gain access to the System via Secure Line Connection but it is the Job of IT Professional to stop unauthorized access. Thus the sudden demand of VOIP's potentially make every node untraceable as VOIP does not access the system through Secure Line Server and use hell of a Bandwidth to be used into talking thus creating a Secure connection via Port 80. The (NPA) thus can't protect the Servers and the Client's on the other ports connected in the Server secure connection as the Local Host Servers are not used for Firewalls and Spam Filtering. So next time you use VOIP think about the Havoc you may create to the Mother System......
