ABSTRACT
Downloading is the most important thing when you are using the Internet. It is the simple truth that everyone who has experienced in it knows. In Vietnam, there are over 50,000,000 Gigabytes which were downloaded from the Internet to computer each month [1]. At the early days of Internet, computer scientists have focused on creating a new technology to help people to share data with the best benefit and the highest speed. Nowadays, there are two technologies which are the most popular in the world. They are Direct Protocol and Peer-to-Peer (P2P) Protocol. This essay will provide a general knowledge of each technology and some suggestion to choose the best Download Programs.
INTRODUCTION
OVERVIEW
The essay was divided into 4 main parts. Part I focuses on the History of File-Sharing Technology. Part II addresses the definition of each technology and explains the differences between them. Part III discusses some good and bad features of Direct Protocol and P2P Protocol. Part IV explores how to use some popular download programs via each protocol and provides a brief conclusion.
HISTORY
When the 8-inch floppy disk was developed by IBM, sharing files was pretty easy – you copy the original data files, and then borrow the disk. Obviously, there were only a few computers around back then, but this happened again almost two decades later, when optical and flash media became nothing out of ordinary.
A few years later, in 1978, CBBS becomes the first Bulletin Board System (BBS) [2], but BBS access is limited to phone lines until early 1990s. Anyway, almost two decades ago, BBS was probably the most widely used file sharing method.
In 1979, Tom Truscott and Jim Ellis came up with Usenet. It is a network that was initially based on the UUCP protocol for dial-up connections and has, since being transported over the Internet, used a specialized client-server protocol, the Network News Transfer Protocol (NNTP). Its main purpose was the exchange of text based messages, but through attachments allowed users to encode files and distribute them to participating subscribers of Usenet Newsgroups. Usenet remains one of the largest carriers of file sharing and Internet traffic. Legal challenges to P2P systems have spurred a resurgence of Usenet. Usenet itself has also been the target of legal challenges pertaining to its use in file-sharing.
In 1985, the FTP protocol becomes standardized, and in 1988, IRC is born.
In 1990, the real thing starts with the formal proposal of the World Wide Web, followed by the introduction of the MP3 standard, at the end of 1991[3].
In June 1999, Napster was released as a centralized unstructured peer-to-peer system, requiring a central server for indexing and peer discovery. It is generally credited as being the first peer-to-peer file sharing system. In the case of Napster, an online service provider could not use the "transitory network transmission" safe harbor in the DMCA if they had control of the network with a server. Many P2P products will, by their very nature, flunk this requirement, just as Napster did. Napster provided a service where they indexed and stored file information
