How Peer to Peer (P2P) Works
Peer to Peer (P2P) Technology- How it works:
Ever wondered how P2P works? This guide will run down most of the major P2P services and how they work. Peer to Peer technology lets people share files over a network on the internet. Most people now use what is known as the second generation of P2P, which is unlike its predecessors like such as Napter, the second generation has no centralized server, making it harder for it to shut down.
How first generation P2P services worked:
A connection is established by a peer finding another peer to connect to. Each peer exchanges active peer and their addresses. When a connection has been established, the user can then search for files. When a search has been submitted, it connects to all nodes on its connection list. The results are then displayed and a connection is made.
How second generation P2P services worked:
Gnutella2: Hubs are used to quickly search for files, eliminating the original "find peer and search" method. Instead, they store a list of files on all the "Leaves" (A peer) that are connected to it, thus dramatically reducing search time. Advantages: Unlike Napster, if a hub crashes, it's network stays alive. Disadvantages: Doesn't make network any more durable than the first generation of P2P. Gnutella2: www.gnutella.com
FastTrack: Programs such as Kazaa and iMesh use the FastTrack protocol. Normal peers connect to a supernode which acts jsut like a hub. Supernodes also connect to other supernodes, allowing search requests to move through the network very quickly. Peers then establish a direct connection to a client after a file has been found. Advantages: Any client can become a supernode. Disadvantages: Corruption of files occur. Clients include: Kazaa (www.kazaa.com), iMesh (www.imesh.com)
BitTorrent: .torrent files are used to store information about the file being shared. Once a torrent file is opened, the client connects to the tracker which tells the client where the file is located and what other peers/seeders there are. BitTorrent works by chunks of small files being transferred (even through multiple connections), while you are downloading. The files are checked for corruption as the download continues. Leechers are people who download and don't upload, and are highly frowned upon on some sites, disallowing them from downloading any further. Advantages: Very fast for popular, new files. Disadvantages: Trackers are unreliable and if it goes down, the file is lost. Clients include: Azureus (www.azureus.com), Shareaza (www.shareaza.com).
EDonkey Network: Edonkey runs on the same principle as first generation P2P, only anybody can become a server. Clients communicate with the server to download files, and random chunks can be downloaded in any order then put together in the end. Advantages: No file corruption, leech penalization. Disadvantages: It can penalize users unfairly. EDonkey: www.edonkey2000.com

3G EV-DO or How the Internet Got Its Wings!
The Internet, as most people know it, is history.
How to Choose Best ISP for Your Needs
Well, the Internet access industry is starting to shake its way out. The much-anticipated consolidation of access providers is nearing its end. In broadband, this means that most users have little or no choice of providers. Though many of the changes have been hard on user choice, this is not necessarily a bad thing. In some cases, it's better to have one stable and pricey provider than 100 unstable, cheap providers. The shakeout was painful for scores of users who often were left with no connection when they needed it most. And some providers left standing don't exactly have good track records, either.
Finger Protocol - TCP/IP Suite
The "finger" protocol is used to return information on users on a specific host. Information that can be gained by using the finger is to see if someone is actively logged on to a server, or find a valid username. The finger protocol is far less prevalent now than it once was due to some problems with the protocol. Back in 1988 an Internet worm exploited an error in the protocol, and additional it was used by mischievous people to find information about server users. Finger had the potential to provide one of these mischievous users with information such as login name, phone number, and the last time the user had logged on to the system.
Broadband is State-of-the-Art Internet Access: How Can a Broadband Cable Benefit You?
We are now well ensconced in a time when the Web is riddled with graphics, animations, sounds, and videos, bringing about a necessity for superior internet access such as that which broadband can provide. The fact is that anything less than the speed supplied by a broadband cable has become inadequate for today's Web users.
The Coming Television Revolution
The revolution is just getting started and will be begin to make its mark this year. By 2010, it will begin to take off. By 2025, it will be the standard for all TV viewing. It's called Internet Protocol Television, or IPTV for short. IPTV works with a set-top box connected to any broadband interface and to a TV. It will allow users to choose among thousands (and eventually hundreds of thousands) of hours of programming, including movies, sports, classic TV, etc., and download their selections from the internet to the hard drive of the set-top box.
DSL Internet is a Simple and Easy Way to Get Fast Internet Service
DSL ? which stands for Digital Subscriber Line ? is a great way to get high-speed internet service, without having to get a cable modem, or live in an area that has cable lines. DSL providers have very fast and comparatively cheap internet connectivity.
ICMP Protocol - Internet Control Message Protocol
The Internet Control Message Protocol communicates errors messages between systems that require attention. This error is not usually at the user level, the error is handled by the application layer. In the OSI Reference model, ICMPs are generally considered part of the IP layer.
Time to Redefine Telecom
Telecommunication, according to Wikipedia, is the extension of communication over a distance. In practice, it also recognizes that something may be lost in the process; hence the term 'telecommunication' covers all forms of distance and/or conversion of the original communications, including radio, telegraphy, television, telephony, data communication and computer networking.

Beta Testing First Mobile Internet Satellite Broadband, Part III
Back in 1999 when we beta tested the first wireless mobile office with satellite broadband Internet we had something that no one lese had. Today you can buy these systems for $5,500 fully installed on any RV. We probably had $10,000 in the first system and we had mobile satellite number 34. Today there are thousands of systems out there. Continuing the beta testing story of the first broadband satellite internet system.

It is using the full electromagnetic spectrum, which we mainly experience, through the twelve-chakra centres and in the DNA.
Why Choose Dial Up ISP Services
Dial up ISP service is the cheapest choice of any of the ISPs and may be a good option for that family on a tight budget. The software upgrades have definitely increased the speed of dial up ISPs, but their speed is still slower than some other options. Dial up ISP service can be purchased from several different companies including Earthlink, AOL, Juno, and others.
Approximately 4 million people in the UK use ADSL with an extra 2 million using a cable connection, meaning 6 million people in the UK have an always-on internet connection. Of these over 1.7 million are subscribed to BT's broadband package, making them the UK's main broadband provider.
