Glossary

all-in-one search tool A tool that provides search forms for several search engines and directories all in one site. The tool also provides hyperlinks which allow you to go to the services directly.

annotated directories Often referred to as virtual libraries, these directories have brief summaries, descriptions, ratings, or reviews attached to Web pages and subject guides.

annotation A brief summary or description of a Web page or of any work listed in a database.

anonymous FTP A means of using FTP to make files readily available to the public. If you start an FTP session with a remote host, you give the log in or user name anonymous and enter your email address as a password. When you use a URL starting with "ftp://" and a domain name with a Web browser, an anonymous FTP session begins, and you don't have to enter a user name or password.

article A message or file that is part of a Usenet newsgroup.

asynchronous communication Communication where the sender and receiver don't participate at the same time, for example, email or voicemail.

attachment A file that is sent as part of an email message but that is not part of the main message. Usually images, programs, or word processor files are sent as attachments, because most email programs allow only plain text in the body of a message.

avatar An icon, image, or figure that you can use to represent yourself in a chat room.

B

bibliographic database An online database that lists sources of information and describes the information but that doesn't include the text of the information itself. Some bibliographic databases are annotated, which means that there is a brief summary of each work listed.

blog  A Web site that is updated frequently with new information about a particular subject or range of subjects.  Entries can be provided by the site owner, taken from other Web sites or outside sources, or contributed by users.  Content is displayed in reverse chronological order, and comments from readers are often encouraged.  While most blogs are text-based, there are also blogs that focus on music, art, video and audio. 

blogroll   A list of blogs that a blog writer, or blogger,  recommends to others. 

bookmark A hyperlink that is saved in the bookmark list, a file in your browser. You can use bookmarks to keep track of favorite or important sites and to return there whenever you are on the World Wide Web. See also: Favorite.

Bookmark list A list of hyperlinks to items on the World Wide Web.

Boolean logic  Search expressions that use Boolean operators (AND, OR, and NOT) in the search expression. Especially helpful in multifaceted or specific topics, Boolean operators help expand or narrow the scope of your search. A search for rivers OR lakes returns all documents with both words or either word in them. A search for rivers AND lakes returns documents with both words in them. A search for rivers AND lakes NOT swamps returns only documents that mention both rivers and lakes but omits those that also mention swamps.

browsing The process of clicking from one hyperlink to another on the World Wide Web. You can browse indiscriminately, or you can do structured browsing, using a hierarchical subject list in a directory.

C

cache A portion of memory (either in RAM or on a disk) set aside to hold the items retrieved most recently. For a Web browser, this refers to recent Web pages and images. The cache is used so that items may be retrieved more quickly without going back to the Internet. A browser can be set so that, in case an item hasn't changed, it will retrieve the item from the cache.

case sensitivity The ability of a search tool to distinguish between uppercase and lowercase letters. Some search tools aren't case sensitive; no matter what you type, the tool only picks up lowercase matches. Search engines that are case sensitive will strictly follow the search request; they'll return documents containing the words in the case in which they were entered in the search expression.

certificate authority A company that guarantees the identity of the holder of a digital certificate. A certificate is attached to a message or Web page and can be used to guarantee the authenticity of information.

chat room A conference or forum that allows two or more people to converse with each other at the same time by taking turns typing messages.

commercial database A database that requires you to pay a subscription cost before accessing it. See also proprietary database.

compressed file A file that has been processed by a program that applies an algorithm or scheme to compress or shrink a file. A compressed file must first be uncompressed or transformed before it can be read, displayed, or used. Files available through anonymous FTP are often stored in compressed form.

concept searching A feature enabling a search engine to find synonyms in its database. When you type in a word or phrase, the engine automatically searches for the word or phrase you want, plus words or phrases that may mean the same thing. For example, if the word teenage is in your search expression, the search engine would also look for the word adolescent.

content area The part of a Web browser window that contains the current Web page, including images, text, or hyperlinks.

copyright The right to copy or duplicate material such as images, music, and written works. Only the owners of the information can grant this right. Regardless of whether information on the Internet or a Web page is accompanied by a statement asserting copyright, it is still protected by the copyright laws of the United States, the Universal Copyright Convention, or the Berne Union.

delimited format A format often used to store tables of data. The data fields are separated by commas, tabs, semicolons, or some other delimiter. Spreadsheet programs usually include the facilities to import data that is in delimited format.

Dewey decimal classification system Originated by Melvil Dewey in the late nineteenth century, this classification system for library materials divides all knowledge into ten different classes, which are then subdivided into several sets of subclasses. Within these subclasses, decimals reflect still smaller subdivisions. The Dewey decimal classification system is most prevalent today in public libraries, whereas most other types of libraries, including academic ones, use the Library of Congress classification system.

digital certificate A device that is used to encrypt and decrypt information, and to guarantee the identity of the sender and the authenticity of the information.

directory Topical lists of Internet resources, arranged hierarchically. Directories are meant to be browsed, but they can also be searched. Directories differ from search engines in one major way -the human element involved in collecting and updating the information.

field searching A strategy in which you limit a search to a particular field. In a search engine, you might search only the URL field. In a library catalog, you could search for items by author, title, subject, call number, or any other data element that was designated as a field. By narrowing the scope of searchable items, field searching helps to eliminate the chance of retrieving irrelevant information.

file name extension The end of a file name in some operating systems where the name of a file ends with a period followed by (usually) two to four letters. The extension is used to associate an application program with the file. For example, the file containing this glossary is named glossary.doc. The file name extension is .doc. Clicking on the name of the file automatically opens the file with the Microsoft Word word-processing software.

H

helper applications Programs used with a Web browser to display, view, or work with files that the browser cannot display. For example, Netscape Navigator can display graphic or image files in GIF or JPEG format. If you accessed an image of another type through a hyperlink, then your browser would need a helper application to display it. As another example, some Web browsers can work with several protocols but not with Telnet. If you activate a hyperlink that begins a Telnet session, a Telnet client that is separate from the Web browser must be used. The Web browser can recognize when it's necessary to use specific helper applications.
