    • Internet Tools and Research
      • Dave Ricker
      • Community Relations
    • Overview
      • ARPANet--The global Internet’s progenitor was the Advanced Research Projects Agency Network (ARPANET) of the U.S. Department of Defense.
      • The first networking protocol used on the ARPANet was the Network Control Program.
    • Overview
      • In 1990, the ARPANET was retired and transferred to the NSFNET. The NSFNET was soon connected to the CSNET, which linked universities around North America, and then to the EUnet, which connected research facilities in Europe.
      • The use of the Internet exploded after 1990, causing the U.S. government to transfer management to independent organizations starting in 1995 .
    • Overview
      • Today, the Internet is a public, cooperative, and self-sustaining facility accessible to hundreds of millions of people worldwide. Physically, the Internet uses a portion of the total resources of the currently existing public telecommunication networks.
      • The Internet uses of a set of protocols called TCP/IP (for Transmission Control Protocol/ Internet Protocol). It was developed in 1983 by Robert Kahn, Vinton Cerf, and others, which quickly became the most widely used network protocol in the world.
    • Overview
      • For many Internet users, electronic mail (email) has practically replaced the postal service for short written transactions. Electronic mail is the most widely used application on the net.
      • You can also carry on live typed conversations with other computer users, using Internet Relay Chat (IRC). More recently, applications like Skype have allowed for live voice and video conversations.
    • Overview
      • One outstanding feature of the Internet is hypertext, a method of instant cross-referencing. In most Web sites, certain words or phrases appear in text of a different color than the rest; often this text is also underlined. When you select one of these words or phrases, you will be transferred, via a hyperlink, to the site or page that is relevant to this word or phrase.
      • Sometimes there are buttons, images, or portions of images that are “clickable.” If you move the pointer over a spot on a web site and the pointer changes into a hand, this indicates that you can click and be transferred to another site.
    • Browsing the Net
      • Web browsing is done with a Web browser such as:
      • Internet Explorer
      • Firefox
      • Opera
      • Netscape
      • Safari
      • Flock
    • Email Browsers
      • Types of email browsers:
      • Some Internet browsers
      • Outlook and Outlook Express (Windows)‏
      • Thunderbird (Both Windows and Mac)‏
      • Eudora
      • Postbox
      • Mail (Mac)‏
      • Gmail
    • Internet Search Tips
      • Search engines:
      • Tools and Tips: Use quotes for specific phrases and choose the words you search carefully.

    • RSS Feeds
      • According to Wikipedia:
      • ► RSS (most commonly translated as "Really Simple Syndication" but sometimes "Rich Site Summary") is a family of web feed formats used to publish frequently updated works—such as blog entries, news headlines, audio, and video—in a standardized format.
      • ► An RSS document (which is called a "feed", "web feed", or "channel") includes full or summarized text, plus metadata such as publishing dates and authorship. Web feeds benefit publishers by letting them syndicate content automatically. They benefit readers who want to subscribe to timely updates from favored websites or to aggregate feeds from many sites into one place.
    • RSS Feeds ► RSS feeds can be read using software called an "RSS reader", "feed reader", or "aggregator", which can be web-based, desktop-based, or mobile-device-based. A standardized XML file format allows the information to be published once and viewed by many different programs. The user subscribes to a feed by entering into the reader the feed's URI or by clicking an RSS icon in a browser that initiates the subscription process. The RSS reader checks the user's subscribed feeds regularly for new work, downloads any updates that it finds, and provides a user interface to monitor and read the feeds. ► RSS formats are specified using XML, a generic specification for the creation of data formats. Although RSS formats have evolved since March 1999, the RSS icon first gained widespread use between 2005 and 2006.

    • Blogs
      • According to Wikipedia:
      • ► A blog (a contraction of the term "weblog") is a type of website, usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. “blog" can also be used as a verb, meaning to maintain or add content to a blog.
      • ► Many blogs provide commentary or news on a particular subject; others function as more personal online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs.

      • This is an example of a blog that I have created to share pictures and other family information.

    • USB Drives
      • A flash drive consists of a small printed circuit board typically in a plastic or metal casing and more recently in rubber casings to increase their robustness. This makes the drive sturdy enough to be carried about in a pocket, for example as a key fob, or on a lanyard.
      • Only the USB connector protrudes, and it is typically protected either by a removable cap or by retracting into the body of the drive. Most flash drives use a standard type-A USB connection allowing them to be connected directly to a port on a personal computer.
    • USB 2.0 What is USB 2.0? Finalized in 2001, Universal Serial Bus (USB) 2.0 is a complete overhaul of the Universal Serial Bus input/output bus protocol which allows much higher speeds than the older USB 1.1 standard did. The goal of the new serial bus is to broaden the range of external peripherals that can be used on a computer. A hard drive can easily hit the USB 1.1 bottleneck whereas it now becomes more 'usable' under USB 2.0 conditions. How do I know if my PC has USB 2.0? Open Device Manager and expand the Universal Serial Bus section. There should be an "Enhanced" USB host controller present. What happened to USB 1.1? USB 1.1 allowed a maximum transfer rate of 12Mbits/second. It is now obsolete. How fast is USB 2.0? USB 2.0 has a raw data rate at 480Mbps, and it is rated 40 times faster than its predecessor interface, USB 1.1, which tops at 12Mbps.
    • Firewire The IEEE 1394 interface is a serial bus interface standard for high-speed communications and isochronous real-time data transfer, frequently used by personal computers, as well as in digital audio, digital video, automotive, and aeronautics applications. The interface is also known by the brand names of FireWire (Apple), i.LINK (Sony), and Lynx (Texas Instruments). IEEE 1394 was adopted as the High-Definition Audio-Video Network Alliance (HANA) standard connection interface for A/V (audio/visual) component communication and control. FireWire is also available in wireless, fiber optic, and coaxial versions using the isochronous protocols. Nearly all digital camcorders have included a four-circuit 1394 interface, though, except for premium models, such inclusion is becoming less common. It remains the primary transfer mechanism for high end professional audio and video equipment.
