SPEED UP YOUR BOOT PROCESS

After your login into windows sometimes you may get annoying messages from softwares saying that it is going to expire and so many unwanted windows will open.you can overcome this problem by going to RUN type MSCONFIG a window will open then press the STARTUP tab it will list the softwares that os will load on startup itself,then unmark the against all the softwares you have installed other than the antivirus programs which is to kept marked.This procedure will increase your bootup time as well as saving the time in closing the unwanted windows.

TYPES OF CRYPTOGRAPHY

Cryptography is defined as the secret way of writing.It involves three steps such as encryption,transmission,decryption.The cryptographic process involves an element called key for encryption and decryption.The key is like a password for a folder. It is primarily divided into three different types.They are
1.Symmetric encryption
2.Asymmetric encryption
3.Hybrid encryption
SYMMETRIC ENCRYPTION
In this method the same key is used for both encryption and decryption.By doing so the key should be transmitted from sender to receiver through the network,which is easy for the hackers to obtain the key and decrypt it.This method is very faster because same key is used for both encryption and decryption but is very insecure.This method is on longer in use.


ASYMMETRIC ENCRYPTION
This is a very effective method since the receives will generate a pair of keys(private key and public key).He sends the public key to the sender from whom he wish to receive the data,hacking of this key will not effect because it will only be able to encrypt the data.The sender encrypt the data with public key and transmit over the lines to the receiver.Upon receiving the data the receiver decrypt the message with his private key.The two keys are designed in such a way that the private key will not be derived from public key with the algorithms such as RSA algorithm.This type of encryption is like a padlock where anyone can easily lock(encrypt) just by pressing but the key is required for opening(decrypt).The main disadvantage of this type is that it is atleast 1000 times slower than symmetric method.

HYBRID ENCRYPTION
This method combines the advantages of the above two methods.In this method the data is symmetrically encrypted and the symmetric key is asymmetrically encrypted with the public key of receiver.At the receiver end with the help of his private key the symmetric key is taken out and that key is used to decrypt the data.This method is as fast as symmetric method because here only the key is asymmetrically encrypted which is very small in size and also this method has the security features available in asymmetric method.

Difference between forward slash(/) and backward slash(\)

Many of us has a confusion where to use forward slash and where to use backward slash.The backward slash is used to navigate to the resources out of our system for e.g consider the url http:\\www.google.com\adsense it is used to reach resource outside of your system.The forward slash is used reach the resource within your machine for e.g c:\windows\system32.I hope you understand the difference

Windows xp found no hard drive error

Last week my friend frustrated with the experience of using vista decided to downgrade his hp notebook computer to xp.while installing he was stopped by "windows doesnt found any harddisk" error.he approached me for help.After searching i found a solution and a very interesting fact behind the error.XP doesnt have driver for SATA hard disk,which has to embedded in live cd to recognize the hard disk.The solution for this is to disable SATA native support in bios setting before the system starts to boot.The above setting will disable SATA support and now your hard drive will be recognized by xp.To use xp with SATA you have to embed the driver for your sata with xp live cd using softwares such as nLITE etc.Also another friend of mine told after updating vista it is stable.Anybody who visits my blog please leave a comment even i havent viewed my blog i m typing this through mobile with opera browser.Viewers discretions are invited.
