  1. The Internet The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies. The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.

  2. Web Browser A web browser is the software program you use to access the World Wide Web. The first web browser was Examples of Web Browsers are: Internet Explorer Mozilla Firefox, Opera, Safari Google Chrome

  3. Website A website is a collection of related web pages, images, videos or other digital assets that has a common Uniform Resource Locator (URL). On the Web, you navigate through pages of information--commonly known as browsing or surfing--based on what interests you at that particular moment. Web pages are written in a computer language called Hypertext Markup Language or HTML.

  4. Search Engines A Web search engine is a tool designed to search for information on the World Wide Web. The search results are usually presented in a list and are commonly called hits. The information may consist of web pages, images, information and other types of files. Examples of Search Engines: Yahoo Google AOL Alta Vista MSN

  5. Common Search Parameters Keywords-A keyword search gives you the ability to search profiles for specific words or phrases. Exact Phrases-When you want to search for an exact phrase, you should enclose the entire phrase in quotation marks. Plus/Minus symbols Booleans Wildcards

  6. What is Boolean Search? 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. How do I do a Boolean Search? 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. For example: 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.

  7. USING “WILDCARDS” A wildcard is a character that may be used in a search term to represent one or more other characters. The two most commonly used wildcards are: 1) The question mark (“?”) may be used to represent a single alphanumeric character in a search expression. For example, searching for the term “ho?se” would yield results which contain such words as “house” and “horse”. 2) An asterisk (“*”) may be used to specify zero or more alphanumeric characters. For example, searching for the term “h*s” would yield results which contain such words as “his”, “homes”, “houses”, “horses”, “horticulturalists”, and “herbaceous”. It is usually best to avoid using the asterisk as the first character in a search string. A search term consisting of a lone asterisk and no other alphanumeric characters will retrieve every record from the database. USING “OPERATORS” Operators are used to combine search terms to identify a concept in a document. The two most commonly used operators are: To select documents that contain all of the search elements you specify, use the “AND” operator. For example, searching for “herb and garden” would yield results that contained BOTH words and would not return results containing only one of the words. 2) To select documents that contain at least one of the search elements you specify, use the “OR” operator. For example, searching for “herb or garden” would yield results that contained EITHER or BOTH words.
