1. Introduction
From the beginning stages, the Internet was built through the idea of fulfilling peer-to-peer communication across large distances. Throughout the last decade, Peer-to-Peer (P2P) networking has grown to become worthwhile for use in business models and Internet applications. Studies performed by multiple major Internet Service Providers found that the amount of P2P traffic throughout the Internet is often higher than 50 percent [1]. The high usage is unsurprising, as P2P allows for a combination of the resources available on the computers of each connected user, as opposed to a client/server model where the users rely on the special servers to provide the resources. By presenting each user within the network as both a client and a server, P2P networking allows for applications and services to provide benefits such as real-time distributed processing, communication, collaboration, and content distribution.
2. Peer-to-Peer Network Definition
A P2P network can be defined as a network filled with autonomous peers that is completely decentralized and self-organized regarding resource distribution. The users within the peer-to-peer network form a virtual network that is independent of the actual physical network [1]. The aspects resource distribution and self-organization are key to a P2P network. As such, they are discussed in more detail below:
2.1. Resource Distribution
Within a P2P networking system, the resources to be shared throughout the network are equally distributed without providing unfair advantages for any peer. Each peer is interconnected through the formed virtual network and typically are dynamically given a new Internet address whenever connecting to the network [1, 2]. Due to this, P2P systems a...

...music. Napster worked through the use of a main server hosted by Napster that contained a central repository. Users would connect to this main server to search for a desired MP3 file and the server would search the server database for a different user in possession of that file. Once a user with the file was found, the two users would become directly connected and the file could be downloaded. Due to the use of this central server, Napster could be considered a type of “brokered” P2P networking, as the two peers only connect after Napster resolved the IP addresses between the two PCs [4]. Regardless of the moral or legal issues surrounding Napster, it is irrefutable that Napster was instrumental in how peer-to-peer networks work today.

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.

Before the 1990’s, if people want to listen to music, they just visit a music store and pick up a CD and then put it into a stereo equipment. However, the development of MP3 file format gradually changed the way people listen to music. This format lets everyone download music easily and it can be converted to CD as well. But, there is still a problem: searching MP3 files on the internet is maddening and people seldom can find the music they want. Therefore, the birth of Napster solved this problem, creating a virtual music community in which music fans could use the Web as a “swap meet” for music files. More importantly, Napster is easy to use and it’s free, which expands the range of audience in age. Bandwidth also contributed to Napster’s success. The greater the bandwidth, the faster the file can be transferred. So, Napster really changed the way people listen to music, discover music and interact with music.
What do P2P, File sharing, and Bit Torrent sites have in common? They all are file sharing websites that you can send and look at files with other billions of people. Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images and video), documents or electronic books. Bit Torrent is a website used that is kind of like a peer-to-peer file sharing ("P2P") site which is used to distribute data and electronic files over the Internet. Be warned, though because these websites
In this paper I will look at the issue of net neutrality and some of the ramifications of having net neutrality or not having net neutrality. I will first define what net neutrality is and why it has become such an issue in recent years. I will then provide brief arguments for and against net neutrality. I will then discuss why I believe that the argument in favour of net neutrality is the stronger argument and why I agree with it. Internet Neutrality is the idea that if users of internet service providers (ISPs) pay for a certain level of internet service, such as speed of service, than those users should expect access to the internet, without the ISP favouring, blocking or interfering with access to internet sites, product or services.
According to the text A Gift of Fire, Napster “opened on the Web in 1999 as a service that allowed its users to copy songs in MP3 files from the hard disks of other users” (Baase, 2013, p. 192, Section 4.1.6 Sharing Music: The Napster Case). Napster was, however, “copying and distributing most of the songs they traded without authorization” (A Gift of Fire, Section 4.1.6 Sharing Music: The Napster Case). This unauthorized file sharing resulted in a lawsuit - “eighteen record companies sued for contributory infringement claiming that Napster users were blatantly infringing copyrights by digitally reproducing and distributing music without a license” (Communications Law: Liberties, Restraints and the Modern Media, 2011, p. 359).
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.
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.
Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
All around the world people connected to the internet are downloading free digital content through P2P file sharing software.
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.
The Internet has revolutionized the computer and communications world like nothing before. The Internet enables communication and transmission of data between computers at different locations. The Internet is a computer application that connects tens of thousands of interconnected computer networks that include 1.7 million host computers around the world. The basis of connecting all these computers together is by the use of ordinary telephone wires. Users are then directly joined to other computer users at there own will for a small connection fee per month. The connection conveniently includes unlimited access to over a million web sites twenty-four hours a day, seven days a week. There are many reasons why the Internet is important these reasons include: The net adapts to damage and error, data travels at 2/3 the speed of light on copper and fiber, the internet provides the same functionality to everyone, the net is the fastest growing technology ever, the net promotes freedom of speech, the net is digital, and can correct errors. Connecting to the Internet cost the taxpayer little or nothing, since each node was independent, and had to handle its own financing and its own technical requirements.
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.
The TCP/IP is the most important internet operation protocol in the world. While IP protocol performs the mass of the functions which is needed for the internet to work. It does not have many capabilities which are essential and needed by applications. In TCP/IP model these tasks are performed by a pair of protocols that operate at the transport layer. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP). These two protocols are vital when it comes to delivering and managing the communication of numerous applications. To pass on data streams to the proper applications the Transport layer must identify the target application. First, to be able to attain this, Transport layer assigns an application an identifier. In the TCP/IP model call this identifier a port number. Every individual software process needing to access the network is assigned a un...
