shared by Toni H. on 28 Sep 10 - Cached
  • Voice over Internet Protocol (VoIP, Voice over IP) is a general term for a family of methodologies, communication protocols, and transmission technologies for delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone. Internet telephony refers to communications services — voice, facsimile, and/or voice-messaging applications — that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end.[1] VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream. Codec use is varied between different implementations of VoIP (and often a range of codecs are used); some implementations rely on narrowband and compressed speech, while others support high fidelity stereo codecs.

    Consider creating a video for the project if you're in the wireless group that could be submitted for this award - includes a prize and trip to Florida. We'd love for someone in this group to win the award from Flat Classroom project. it is about how wireless broadband can be used in education. Great idea for a video.

    Competition for envisioning the future of wireless broadband - what could you do with high speed wireless broadband. This competition carries a prize and a trip to Florida this next February - application due November 1st, so a quick turn around. My good friend, Louise Maine, shared this with me. It is a great opportunity. Please share it.

    FCC is considering to allow free Wireless Internet but of course the large wireless carriers are against such a move.

    "We need to reserve some spectrum for free broadband services," Martin said. "This would be lifeline broadband service . . . that would be designed for lower-income people who may not otherwise have access to the Internet."

  • In the 2000s the Internet grew to an astounding level not only in the number of people who regularly logged on to the World Wide Web (WWW) but in the speed and capability of its technology. By December 2009, 26 percent of the world’s population used the Internet and “surfed the web.
  • The rapid growth of Internet technology and usage had a drastic cultural effect on the United States. Although that impact was mostly positive, the WWW caused many social concerns. With financial transactions and personal information being stored on computer databases, credit-card fraud and identity theft were frighteningly common.
  • Hackers accessed private and personal information and used it for personal gain. Hate groups and terrorist organizations actively recruited online, and the threat remained of online terrorist activities ranging from planting computer viruses to potentially blowing up power stations by hacking computers that ran the machinery. Copyright infringement was a growing concern

  • At the turn of the century, most users accessed the Internet by a dial-up connection in which computers used modems to connect to other computers using existing telephone lines. Typical dial-up connections ran at 56 kilobytes per second.
  • raditional communications media such as telephone and television services were redefined by technologies such as instant messaging, Voice over Internet Protocol (VoIP), mobile smartphones, and streaming video.
  • The Internet changed the production, sale, and distribution of print publications, software, news, music, film, video, photography, and everyday products from soap to automobiles.
  • With broadband, Internet users could download and watch videos in a matter of seconds, media companies could offer live streaming-video newsfeeds, and peer-to-peer file sharing became efficient and commonplace. News was delivered on websites, blogs, and webfeeds, and e-commerce changed the way people shopped. Television shows, home movies, and feature films were viewed on desktop or laptop computers and even on cell phones. Students researched online, and many parents began working from home for their employers or started their own online businesses.
  • It was also becoming increasingly easy for users to access it from Internet cafés, Internet kiosks, access terminals, and web pay phones. With the advent of wireless, customers could connect to the Internet from virtually any place that offered remote service in the form of a wireless local area network (WLAN) or Wi-Fi router.
  • In January 2001 Apple launched the iPod digital music player, and then in April 2003 it opened the iTunes Store, allowing customers to legally purchase songs for 99 cents. Although federal courts ordered that music-sharing services such as Napster could be held liable if they were used to steal copyrighted works, Fanning’s brainchild realized the power of peer-to-peer file sharing and the potential success of user-generated Internet services.
  • Email was the general form of internet communication and allowed users to send electronic text messages. Users could also attach additional files containing text, pictures, or videos. Chat rooms and instant-messaging systems were also popular methods of online communication and were even quicker than traditional email. Broadband made other popular forms of Internet communication possible, including video chat rooms and video conferencing. Internet telephony or VoIP became increasingly popular f

    Smarr is one of the people who can legitimately claim the benefit of foresight. He is one of the internet's architects, one of the academics who connected their universities using slow, slow dial-up modem links, just to see what would happen next. He has seen this communication highway grow, and is still at the forefront of research as he explores what he calls "ultra-broadband", asking the question: what will cyberspace look like when it is 10,000 times its current speed?

  • "It has been good for revising what we've been learning because it's with another teacher.

  • "This project is proving that it is possible to interconnect many schools simultaneously," said Beyers.

In addition to increased productivity and reduced business costs, organisations also benefit from a more motivated workforce seeking a better work/life balance.
