Introduction:
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.
In a client-server network, the capability of the server will decline as the amount of clients asking for services from the server increment. In spite of that, in P2P systems overall network performance really enhances as an increasing number of nodes are added to the system. These companions can arrange themselves into a specific purpose groups(ad hoc) as they impart, work together and offer data transfer capacity with another to finish the current workload (sharing of files). Each companion can transfer and download at the meantime, and in a procedure like this, new companions can join the group while old companions leave at whatever time. This active re-association of group peer members is not opaque to ultimate consumer.
Another characteristic of a P2P network is its ability regarding fault-tolerance. At the point when a companion goes down or is detached from the system, the P2P process will continue by utilizing remaining associates. As an illustration, in a Bit Torrent system, any users downloading a certain documents are likewise serving as servers. At the point when a user discovers one of the associates is not reacting...

Before the present time of computers and various media player technology, trading music files on the internet was practically unheard of. Today MP3 music files have become file format that is widely “swapped” over the internet. The problem with trading MP3's is that it violates copyright laws. However, this hasn’t stopped the tens of millions of file sharing software users who continue swap MP3’s. MP3 piracy is a costly business for many companies, and the disadvantages outweigh the advantages of “P2P” file sharing. File sharing is a costly, illegal practice that hurts not only the consumers, but the artists as well.

Peer-to-peer (P2P) networks have had a staggering growth in the past few years. Since Napster, dozens of P2P networks have been created in its imitation. Due to the growing accessibility of broadband, which increases the speed of downloads, P2P networks generate nearly 1.8 billion downloads per month. Popularity and acceptance is still continually growing.

Peer-to-peer is a communications model in which each party has the same capabilities and either party can initiate a communication session. Other models with which it might be contrasted include the client/server model and the master/slave model. In some cases, peer-to-peer communications is implemented by giving each communication node both server and client capabilities. In recent usage, peer-to-peer has come to describe applications in which users can use the Internet to exchange files with each other directly or through a mediating server.
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
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.
TCP/IP is a network model which enables the communication across the Internet. The most fundamental protocol on which the Internet is built. This is made up of the 2 common networking protocols, TCP, for Transmission Control Protocol, and IP, for Internet Protocol. TCP maintains and handles packet flow linking the systems and IP protocol has the ability to handle the routing of packets. However The TCP/IP stack consists of 5 layers first being application layer, the transport layer, then the network layer, the link layer and finally the physical layer. The assignment focuses on the three middle layers and is divided into five parts. Firstly explaining how the TCP and UDP the most vital protocols needed to deliver and communicate.

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.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
All around the world people connected to the internet are downloading free digital content through P2P file sharing software.
