P2P

P2P (peer-to-peer) is a type of network where "each workstation has equivalent capabilities and responsibilities".

MP3's

MP3 is a format that allows audio (usually music) files to be compressed so they are small enough to be sent over the internet or stored as digital files. It is popular because the compression method takes out the sounds that less audible to humans thus retained as much sounds that can be heard by human ear in a relative small storage.

They are shared frequently on P2P networks on the internet. A portion of your hard drive becomes a server, so each P2P member is both a server and a client, both serving and receiving mp3 files. Napster is an example of a "pure" P2P network. Through this type of decentralized system, you are able to communicate from node to node, with out the use of a server.

Home networks

Usually home networks work on P2P because one of them can't be spared to just be a server. Files are shared form each computer held in a shared folder.

WEB 2.0

webmail

Web-based or webmail is email that is accessed through the web and stays on the web. The main benefit is that the user can access their mail at any location with a computer that has a internet connection. The first webmail service was Hotmail and is still one of the most popular.

Discussion boards

replacing newsgroups, a discussion board is an online bulletin board where you can read and leave messages for the public or members of that site. The first discussion boards were available on bulletin board systems.

IM

Instant Messaging - Anyone on a given e-mail system can send a message and have it pop up instantly on the screen of anyone else logged onto that system. examples of instant messaging systems are AOL, MSN and Yahoo
PROS: allows a faster way of communication than email, and can reduce long distance bills CONS: lack of privacy, many IM products don't communicate with another, and can destroy concentration when working.

Blog

A blog (short for weblog) is a personal online journal that is frequently updated and intended for general public consumption. Blogs are defined by their format: a series of entries posted to a single page in reverse-chronological order.Blogs generally represent the personality of the author or reflect the purpose of the Web site that hosts the blog. Topics sometimes include brief philosophical musings, commentary on Internet and other social issues, and links to other sites the author favors, especially those that support a point being made on a post.
Before blogging became popular, digital communities took many forms, including Usenet, commercial online services such as GEnie, BiX and the early CompuServe, e-mail lists and Bulletin Board Systems (BBS).

VoIP

Voice Over Internet Protocol is a type of internet telephony in which the net is used to make phone calls, either one on one or for audio-conferencing. You can make long distance phone calls that are surprisingly cheap or even free.
Skype is one of the most popular program that use VoIP, and is currently expanding into the wireless cellular division. The expansion of the WiMax network will dramatically change the current market of cellular technology.

Webcast

Webcasting is where customized text, video, and audio samples are sent to you automatically on a regular basis. You choose the categories or channels of websites that will automatically send you updated information. It saves time because you don't have to search for the information.
