LimeWire and BitTorrent are the most popular applications that connect your computer to a Peer-to-Peer network. The simplest explanation of this is that you basically share your computer with a large multitude of computer users numbering in the hundreds of thousands. You get to download whatever you like from their computers and they get to do the same to yours. You will find mp3's of just about anything your heart desires, any movie you are interested in and just about any software you like and all of it FREE of CHARGE. There are a couple of problems that you might encounter:
1. Downloads that you copy to your hard drive from this network, are for the most part ILLEGAL. There are a few law suits going on about this and we will have to wait for their outcome. Just keep in mind that Napster had to start charging for similar services in order to stay in business legally. Remember also that some people just like you were sued by the BIG BAD record companies and forced to pay many thousands of dollars for allowing this kind of networking on their computers.
2. You are creating a major security risk by allowing hundreds of thousands of strangers access to your computer.
It is difficult to disapprove of such a great and very useful tool; peer-to-peer networking is a great way of sharing large amounts of data. We have to DISAPPROVE of illegal sharing of data and thus: yellow light - use intelligently.
