Voice over Internet Protocol - Wikipedia, the free encyclopedia - 0 views

  • 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.

  • Global Crossing was founded by Gary Winnick and three business associates in 1997 through Pacific Capital Group, Winnick's personal venture group, which had experienced mixed results in its twelve-year history. In 1997, Global Crossing raised $35 million of capital from the CIBC Argosy Merchant Funds (later Trimaran Capital Partners). The heads of the CIBC Argosy Merchant funds were former associates of Winnick from his days in the 1980s as a salesman at Drexel Burnham Lambert under Michael Milken. CIBC would ultimately realize a gain estimated to be $2 billion from its relatively small equity investment in Global Crossing, making it one of the most profitable investments by a financial institution in the 1990s.[

The World Is Flat - Wikipedia, the free encyclopedia - 2 views

  • The World Is Flat: A Brief History of the Twenty-First Century is an international bestselling book by Thomas L. Friedman that analyzes globalization,
  • #1: Collapse of Berlin Wall--11/9/89: The event not only symbolized the end of the Cold War, it allowed people from other side of the wall to join the economic mainstream. #2: Netscape--8/9/95: Netscape and the Web broadened the audience for the Internet from its roots as a communications medium used primarily by 'early adopters and geeks' to something that made the Internet accessible to everyone from five-year-olds to ninety-five-year olds. The digitization that took place meant that everyday occurrences such as words, files, films, music and pictures could be accessed and manipulated on a computer screen by all people across the world. #3: Workflow software: The ability of machines to talk to other machines with no humans involved was stated by Friedman. Friedman believes these first three forces have become a "crude foundation of a whole new global platform for collaboration." #4: Uploading: Communities uploading and collaborating on online projects. Examples include open source software, blogs, and Wikipedia. Friedman considers the phenomenon "the most disruptive force of all." #5: Outsourcing: Friedman argues that outsourcing has allowed companies to split service and manufacturing activities into components which can be subcontracted and performed in the most efficient, cost-effective way. This process became easier with the mass distribution of fiber optic cables during the introduction of the World Wide Web. #6: Offshoring: The internal relocation of a company's manufacturing or other processes to a foreign land to take advantage of less costly operations there. China's entrance in the WTO allowed for greater competition in the playing field. Now countries such as Malaysia, Mexico, Brazil must compete against China and each other to have businesses offshore to them. #7: Supply-chaining: Friedman compares the modern retail supply chain to a river, and points to Wal-Mart as the best example of a company using technology to streamline item sales, distribution, and shipping. #8: Insourcing: Friedman uses UPS as a prime example for insourcing, in which the company's employees perform services--beyond shipping--for another company. For example, UPS repairs Toshiba computers on behalf of Toshiba. The work is done at the UPS hub, by UPS employees. #9: In-forming: Google and other search engines are the prime example. "Never before in the history of the planet have so many people-on their own-had the ability to find so much information about so many things and about so many other people", writes Friedman. The growth of search engines is tremendous; for example take Google, in which Friedman states that it is "now processing roughly one billion searches per day, up from 150 million just three years ago". #10: "The Steroids": Personal digital devices like mobile phones, iPods, personal digital assistants, instant messaging, and voice over Internet Protocol (VoIP).

  • 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

  • A cell phone is a example of mobile and ubiquitous computing. A cell phone is mobile because it is able to be moved from one place to another. A cell phone is also ubiquitous because two people are able to communicate from different places by calling one another as well as SMS and video messaging. Lastly, a cell phone is classified as a computing device because it accepts input, processes that input into data that the cell phone can read, and produces output as information that a human can read.
  • Mobile and Ubiquitous Computing can be broken down into three separate words that can come together to make one topic. First, mobile means able to be moved. There are many technological mobile devices. There are cell phones, Ipods, portable DVD players, PDAs, laptops, and many other devices that can be moved or transported from one place to another. Second, ubiquitous means being present everywhere at once. Having the ability to stream live from a camera or cell phone to a website over the Internet makes that particular video ubiquitous.

    "The second steroid involves instant messaging and file sharing. Being able to share files from peer to peer is considered ubiquitous because the files can be everywhere and mobile because the files can be moved. Instant messaging is a huge breakthrough in the technological world. People can send instant messaging via cell phone, computer , PDA. This steroid revolutionized communication."
