Digitizing - Wikipedia, the free encyclopedia - 0 views

  • Digitizing or digitization[1] is the representation of an object, image, sound, document or a signal (usually an analog signal) by a discrete set of its points or samples. The result is called digital representation or, more specifically, a digital image, for the object, and digital form, for the signal. Strictly speaking, digitizing means simply capturing an analog signal in digital form. For a document the term means to trace the document image or capture the "corners" where the lines end or change direction.

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.

Podcast - Wikipedia, the free encyclopedia - 0 views

  • A podcast (or non-streamed webcast) is a series of digital media files (either audio or video) that are released episodically and often downloaded through web syndication. The word usurped webcast in common vernacular, due to rising popularity of the iPod and the innovation of web feeds.

Cell Phones in Learning - Liz Kolb - 0 views

  •  
    Cell phones have the capability to become the "Swiss army knife" for student research and organization. First, we explore using cell phones as data collection tools: audio recorders, digital cameras, and digital camcorders. Additionally, we consider how classroom projects can be developed for cell phones: creating ring tones, text messaging, mobile WebPages, and mobile surveys. Finally, we contemplate the future features of cell phones and how those features play a role in learning.

History of Google - Wikipedia, the free encyclopedia - 0 views

  • On Wednesday, January 18, 2006, the U.S. Justice Department filed a motion to compel in United States district court in San Jose seeking a court order that would compel search engine company Google Inc. to turn over, "a multi-stage random sample of one million URL’s", from Google’s database, and a computer file with, "the text of each search string entered onto Google’s search engine over a one-week period (absent any information identifying the person who entered such query)."[68] Google maintains that their policy has always been to assure its users privacy and anonymity, and challenged the subpoena. On March 18, 2006, a federal judge ruled that while Google must surrender 50,000 random URLs, the Department of Justice did not meet the necessary burden to force Google to disclose any search terms entered by its users

Mobile device - Wikipedia, the free encyclopedia - 0 views

  • A mobile device (also known as a handheld device, handheld computer or simply handheld) is a pocket-sized computing device, typically having a display screen with touch input and/or a miniature keyboard. In the case of the personal digital assistant (PDA) the input and output are often combined into a touch-screen interface. Smartphones and PDAs are popular amongst those who require the assistance and convenience of certain aspects of a conventional computer, in environments where carrying one would not be practical.
  • andheld devices have become ruggedized for use in mobile field management situations to record information in the field. They are used to achieve a variety of tasks for increasing efficiency that include digitizing notes, sending and receiving invoices, asset management, recording signatures, managing parts and scanning barcodes.

    Digital Underclass & great information from the BBC.

    Fascinating listens from the BBC - their essential guide to the 21st century. A fascinating term that I cannot recall hearing is the "digital underclass" -- People who have "no chance of every going online." They are predicting that these people will be responsible for the next shift in the balance of power in the new century.

    I highly recommend that elementary and middle schools at least sign up for a school code for woogi world - this is a great tool suggested by Hoover City schools for teaching digital citizenship. My daughter (my intrepid tester of all kid virtual worlds) loves it and says she thinks it is great for kids.

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).
