Abstract: This paper discusses peer-to-peer file sharing and distributed computing.
In the mid-1980s, the term P2P, or peer-to-peer, was used by local area network vendors to describe the computing nodes on their networks. Previous to that, the term was used to describe ARPAnet, the military-backed computer network that would become the model for today's Internet[1]. Today however, the term P2P has a very different meaning - it has come to describe applications designed specifically to exploit peer relationships between computers, using the Internet as an extension of the local network[2]. Its primary uses include not only the sharing of huge amounts of information, but also the sharing of free resources on a vast number of computers [3]. The reasons for its success are numerous and the problems that it creates are genuine.
Peer-to-peer networking has existed for years. The IP routing structure of the Internet is still peer-to-peer, albeit with several layers of hierarchy, and individual routers act as peers in finding the best route from one point on the net to another[4]. However, it is only recently, with the development applications that utilize P2P to create vast stores of media files, that it has become immensely popular. While these applications only account for a fraction of peer-to-peer networking's uses, they have received the majority of the attention.
PEER-TO-PEER FILE-SHARING
These peer-to-peer file-sharing systems have changed the way we think about sharing data over the Net and their success can be attributed to a number of factors. Firstly, these file-sharing systems have simple implementations that make them accessible to regular people. Not only is downloading a file using these systems simple, but uploading one is easy as well. Separate programs need not be used, and the process is often invisible to the user[5]. Further, because these systems are often used with media files such as MP3s, the same data exists on a number of different accessible computers. Because of this redundancy, accessing this data becomes reliable. In addition, because of the type of content that is being shared, a trust relationship is not required between the provider of the data and the person accessing it - there is little to no consequence to receiving a corrupted media file[6].
Perhaps the two most crucial elements of the success of such systems are that they allow an incredible number of files to be gathered through the amalgamation of the files on many computers, and that increasing the value of the databases by adding more files is a natural by-product of using the tools for one's own benefit[7].

Whereas for Nora is trapped in her own predicament and circumstances. She has no power or equality in society, or even in her own marriage and household. She has a financial obligation, the back loan she did behind her husband’s back. To obtain the loan she had forged her father’s signature on the IOU. Nora claims that she can’t claim her own life or live her own life so long as she remains married to her husband. She goes on to say how she feels all her life she’s been played with like a
Nora 's character is a little bit complicated. she is a representative of women in her time and shows how women were thought to be a content with the luxuries of modern society without worrying about men 's outside world. However, Nora proves that this idea is entirely wrong. Nora is not a spendthrift as all people think specially her husband. on the contrary, she has a business awareness and she is mature
The first online peer to peer file-sharing application was Napster. Napster allowed people to copy music from their CDs onto their computers in mp3 format. They then allowed other members of Napster to download these songs onto their computers. Once this caught on, millions of people were downloading thousands of songs a day. And as you can imagine, this did not make the record companies happy with the idea that people were getting their music for free instead of buying the CD. It also caused a problem with some of the recording artists. Most notably Metallica.
“I believe that first and foremost I am an individual, just as much as you are—or at least I’m going to try to be. I know most people agree with you, Torvald, and that’s also what it says in books. But I’m not content anymore,”(1017) bemoans Nora Helmer, the protagonist of the play, A Doll’s House, as she relinquishes social benchmarks by abandoning her husband. A Doll’s House, written by Henrik Ibsen, examines the central theme of individual desires conflicting with social ideals. In the play, A Doll’s House, Ibsen applies effective characterization to strengthen the characters; Kristine Linde, Torvald Helmer and Nora, which enable him to develop the fundamental theme. Ibsen develops the static characters; Kristine and Torvald, to establish

Peer-to-peer (P2P) is a substitute network design to the conventional client-server architecture. P2P networks utilize a decentralised model in which each system, act as a peer, and serve as a client with its own layer of server functionality. A companion plays the role of a client and a server in the meantime. That is, the node can send calls to other nodes, and at the same time respond to approaching calls from other companions in the system. It is different from the traditional client-server model where a client can just send requests to a server and then wait for the server’s response.
With the popularity of the Internet, sales for CDs, DVDs, Movies, and many other products have increased. Along with the increase of sales has brought forth an ever increasing problem of illegal media being downloaded. Programs such as Bittorent, Kazaa, and other direct-connect networking programs have allowed the transferring of such illegal media. Downloading song files from the Internet over a free peer to peer network is the moral equivalent of shoplifting music CDs from the local mall.
