Verify the authenticity of a website before you purchase a product or research distance-learning education for your next degree. Introduction When you're performing daily tasks online and browsing various websites, you may not always think to investigate as to whether the website is legitimate. As long as you're just reading content, it may not be a huge issue, but before you make a purchase with a website that you're not familiar with, it's best to do a quick check. You can verify that a website is legitimate by checking the InterNIC network information website. http://www.youtube.com/watch?v=_8yKNJCTck4 Key Terms Defined InterNIC - InterNIC is the "Network Information Center" of the Internet. It maintains records of online websites and allows individuals to file complaints against website registrars (the companies that provide services to website owners). Database - Databases are usually collections of journal and magazine articles, dissertations, reviews, and abstracts. A database consists of individual records. Key Terms Defined Internet - The Internet lets you transfer information around the world in seconds. It is a global collection of networks, both big and small. These networks connect together in many different ways to form the single entity that we know as the Internet. One of the greatest things about the Internet is that nobody really owns it. Registrar - is an ICANN or Internet Corporation for Assigned Names and Numbers accredited company who has the authority to register domain names. Registrars are competitive retailers of domain names like .info, .coop, .mobi, .name, .pro, .museums, and others. Key Terms Defined URL - Abbreviation of Uniform Resource Locator (URL) it is the global address of documents and other resources on the World Wide Web. The first part of the URL is called a protocol identifier and it indicates what protocol to use, and the second part is called a resource name and it specifies the IP address or the domain name where the resource is located. Examples: ftp://www.pcwebopedia.com/stuff.exe and http://www.pcwebopedia.com/index.html Key Terms Defined Legitimate - according to law; lawful: the property's legitimate owner, in accordance with established rules, principles, or standards and in accordance with the laws of reasoning. How to Tell If a Website is Legitimate Look for consistency in design. Your first line of defense is a critique of the flow and "readability" of the website. Ask yourself if images and text are arranged in a way that is easy to follow. Legitimate websites most often do not look as if they have been hastily thrown together. A website worth its weight will employ established rules of design with text, images and navigation. How to Tell If a Website is Legitimate Research websites that claim to be businesses before you perform transactions or provide information. The Better Business Bureau is a good place to start. Be absolutely sure a website is trustworthy before you enter any private information, including passwords. Hypertext transfer protocol secure (HTTPS) indicates a type of network security protocol. The "s" in "https" literally stands for "secure." Boolean Searches http://www.youtube.com/watch?v=jMV7X3W_be g Boolean searches - allow you to combine words and phrases using the words AND, OR, NOT and NEAR (otherwise known as Boolean operators) to limit, widen, or define your search. Most Internet search engines and Web directories default to these Boolean search parameters anyway, but a good Web searcher should know how to use basic Boolean operators. Boolean Searches How to do Boolean Searches You have two choices: you can use the standard Boolean operators (AND, OR, NOT, or NEAR, or you can use their math equivalents. It depends on you, the searcher, on which method you're more comfortable with. http://www.youtube.com/watch?v=vube-ZcJFk4 Boolean Searches Boolean Search Operators •The Boolean search operator AND is equal to the "+" symbol. •The Boolean search operator NOT is equal to the "-“ symbol. •The Boolean search operator OR is the default setting of any search engine; meaning, all search engines will return all the words you type in, automatically. •The Boolean search operator NEAR is equal to putting a search query in quotes, i.e., “Sponge Bob Squarepants". You're essentially telling the search engine that you want all of these words, in this specific order, or this specific phrase. Boolean Searches More Examples • Using AND narrows a search by combining terms; it will retrieve documents that use both the search terms you specify, as in this example: Portland AND Oregon Using OR broadens a search to include results that contain either of the words you type in. Example: Liberal OR Democrat Using NOT will narrow a search by excluding certain search terms. Example: Oregon NOT travel Using Boolean Advance Search
