Hidden Sound track in Windows Xp
Windows XP has a hidden sound track which plays as background music during Windows XP installation process, but most people can’t hear this music because they have a sound card that does not have drivers preinstalled on XP .
There are 2 ways by which you can find this hidden sound track:
1.Go to start->search.Search for title.wma .But remember to include hidden files and folders in your search.
2.Navigate to C:\Windows\system32\oobe\images, go to Tools > Folder Options > View, check Show Hidden Files and Folders options and then uncheck Hide Protected Operating System Files. You will now notice a file called title.wma, that is the hidden sound track.

Lets play with Characters and Strings!
Single character-
input- getchar(variable name) or variable name= getchar()
output- putchar(variable name)
Multiple characters (Strings)-
Note: A String is nothing but an array of characters.
input- gets(variable name)
output- puts("text here...") or puts(variable name)
Formatted I/O functions:
1. scanf(): This function is used to input formatted data from the user or in other words we can say that this function can be used to input any type of data.
Syntax- scanf("Format specifier", &Variable name);
DATA TYPE FORMAT SPECIFIER
char %c
string %s
int %d
float %f
double %lf
2. printf(): This function is used to display formatted output or in other words we can say that this function can be used to display any type of data in a formatted manner.
Syntax- printf(".........Format specifier......control string.....", variable name);
Escape Sequences:- \n, \t, \b, \a can also be used.
More About Data Types:
DATA TYPE USED TO STORE SIZE RANGE
Char (%c) Single character 1 Byte -128 to 127
Int (%d) Integers 2 Bytes -32768 to 32767
Float (%f) Single Precision 4 Bytes 3.4E-38 to 3.4E38
Decimal numbers
Double (%lf) Double Precision 8 Bytes 1.7E-308 to 1.7E+308
Decimal numbers
Examples:
WAP to get the name of user entered and display the same.
#include<stdio.h>
main()
{
char nm[10];
gets("Enter your name:\n");
gets(nm);
puts("Name: ");
puts(nm);
getch();
}
WAP to get the name, enrollment number, address, gender, course name, marital status and fees from the user.
#include<stdio.h>
main()
{
char name[10], add[20], gn[5], course[10], ms;
int en;
float fee;
printf("Enter your Enrollment number\n");
scanf("%d", &en);
fflush(stdin); \\To clear the input stream
printf("Enter your name:\n");
gets(name);
printf("Enter your address:\n");
fflush(stdin);
scanf("%s", &add); \\Another way to enter any string
printf("Enter your gender:\n");
fflush(stdin);
gets(gn);
printf("Enter your course name:\n");
fflush(stdin);
gets(course);
printf("Enter your marital status:\n");
fflush(stdin);
ms=getchar();

All about VPN
What is VPN ?
VPN is a short form of Virtual Private Network, as a name suggest it is related to privacy. It extends your private network over the public or shared networks example Internet, and you can use these networks as if they were your private network and it will include all the security, management policies and functionality of the private network. It have point to point connection through the dedicated connection or encryption, or it can contain both these. The point to point connection can be between any of these two :-
two networks, two servers, two clients, or between client and server.
Technically, VPN connection is over the large area i.e. Wide Area Network (WAN) but for the user it appears as if it is a private link, therefore the name comes 'virtual private network'.
How it works
VPN is basically used to connect the two device and send the data. Lets say, you work in a company and want to send some important information immediately to the company server so that your team can analyze and use the information, so first thing to use VPN is, you need to have VPN software installed in your system.When you try to connect with your company server, your VPN software try to establish a connection with your VPN server using the tunneling protocol in which all the management policies, authentication and encryption of the connection is incorporated. After the remote device or computer is successfully authenticated a secure connection, also called tunnel, is established. Now whatever information you try send, will transfer through this tunnel and that will be encrypted at the sender's end and correspondingly decrypted at the receiver's end. Hence, even though we are using the untrusted channel for the connected are data is much secure.
The types of VPN are :
L2TP VPN - Layer 2 Tunneling Protocol VPN;
PPTP VPN - Point to Point Tunneling Protocol VPN.
Open VPN -It is a free & open source virtual private network program for creating a server-to-multiclient or point-to-point encrypted tunnels between host computers.
Why to use VPN or What is the need ?
1. Anonymously use network
VPN hide your identity from the hackers or ISP which keep the track of your IP address. It also provide the option change your IP every minute.
2. Increase Security
VPN creates a tunnel to exchange data and everything passing through tunnel encrypted at the sender's end and decrypted at the receiver's end. Hence,data is invisible to the outsider, therefore add an additional layer of security.
3. Bypass region restriction
If you want to see movies or visit any website which is restricted in your area you can use VPN. Some VPN services provide option to select the regional IP address. So, find out region where your website or web page is not restricted and change your IP address accordingly.
4. Provide a Virtual firewall
VPN protect your IP address, so whenever you use VPN your computer or your device address will not be seen.
5. Prevent password sniffing for Hot spot users
Nowadays, hot spots are present every where which is very convient to use but at same time it very dangerous because a hacker may sniff through the network and steal your important information like password.VPN concept of using tunnel prevent the sniffing of your send and received data, hence decrease the risk.
