Digital Rights Management (DRM) is the means copy right holders protect their content so that it only is consumed as intended. Encryption can play a part in the protection by scrambling the content in such a fashion as it can only be decrypted as the copyright holder see's fit.
someone give the answer I need it now!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Generally a feeder mechanism is a subordinate part of a larger production process. It provides and supplies materials to a production process, machine or person for further manufacturing and modification of a product to be carried out.
The layer of the OSI Model that deals with encryption, would be the sixth layer, the presentation layer. It deals with the SSL/TLS protocol which pretty much just turns your regular HTTP (hypertext transfer protocol) into HTTPS (hypertext transfer protocol secure.) It adds an encryption to certain web pages that would deal with you credit card or any other private information dealt with.
The exact mathematics of the encryption differ depending on the algorithm used, but in principle, this is how it works. An algorithm is used to generate a pair of keys that are related mathematically. In many cases they are factors of a very large number. One of the keys is the Public key, which is published to a key registry. The other is the Private key which is held by the owner alone. The important thing is that it is supposed to be impossible to derive the Private key from the Public key. When the owner wants to send a message, the use the Private key to encrypt it or to sign it. Since only the corresponding Public key can decrypt it, that establishes that the sender is who they say they are (because only they should have the Private key). If the sender used their Private key to sign the message, the receiver can use the Public key verify that the message has not been tampered with. On the flip side, some can encrypt a message to the owner of the Private key by using that person's Public key. Only the holder of the Private key can decrypt the message. This can provide confidentiality. Two correspondents can establish secure communications by using each others Public keys to encrypt their messages. Often the public key is deposited with a trusted Certificate Authority. Assuming the user trusts the key repository, they can use them to authenticate the key they are using as belonging to the person it is supposed to belong to. To get more details on the mathematics of encryption and decrption using Public Key Encryption, aka asymmetric encryption. Do a web search for the particular algorithm involved, be it SSH, PGP, TLS, or some other protocol.

If you are using an encrypted channel, then at some point everyone uses symmetric encryption. It is fast (compared to asymmetric).The first part of an encrypted conversation will probably use asymmetric encryption to provide the shared private key that is later on used for the bulk part of data conversations on an encrypted channel.
The word transferred is a verb. It is the past tense of the verb transfer.
In symmetric key techniques there is a single key and that key is kept secret. Symmetric key is a like a sub part of classical encryption.
