Access Counters
An access counter actually displays the number of visitors while an access tracker displays either a counter or a logo, but also provides more site statistics if you click on the counter or logo. Counters can be visible or invisible on the Web site. Most counters simply count accesses ("hits"), but a few counter services also serve as trackers and provide the number and percentage of visitors based on operating system (Win95, Win 3.1, Macintosh, etc.), browser (Netscape, MSIE, etc.), domain (e.g. COM, NET,EDU, ORG, and country-specific domains), as well as traffic by hour, day, week, and month.
Application Server
A computer in a Local Area Network (LAN) that hosts shared network applications. See Server.
Bandwidth
The transmission capacity of an electronic line such as a communications network, computer bus or computer channel. It is expressed in bits per second, bytes per second or in Hertz (cycles per second).
Bookmark
A stored location for quick retrieval of a Web site. Web browsers provide bookmarks that contain the Internet addresses (uniform resource locators, or URLs) of favorite sites.
BPS
(Bits Per Second) The speed of data transmission is measured in bps or baud rate. The larger the bps, the more data that can flow over the line in a shorter amount of time.
Byte

Capture Cards
Devices which take the analog TV signal and convert it to digital information.
CGI
(Common Gateway Interface) A standard for interfacing external applications with information servers. In other words, CGI allows a Web site application, such as a form, to "talk" to the server that actually performs the application.
Cryptography
The conversion of data into a secret code for secure transmission over a public network. The original text, or plaintext, is converted into a coded equivalent called ciphertext via an encryption algorithm. The ciphertext is decoded (decrypted) at the receiving end and turned back into plaintext.
Cyberspace
The Internet, or the digital world in general.
Data Compression
Storing data in a format that requires less space than usual. Useful in communications because it enables devices to transmit the same amount of data in fewer bits, or in backup utilities, spreadsheet applications, and database management systems to reduce storage and memory space used.
Decrypt
To convert encrypted data back into its original form.
Domain Name
An organization's registered unique name used for its Internet address. See URL.
Download
To bring a file or application from the Internet to a computer.

Host
A computer server that houses the information content of a Web site, and links the information to the Internet. May be part of the services provided by an ISP (Internet Service Provider).
HTML
(HyperText Markup Language) A document formatting language used on the World Wide Web. Web pages are built with HTML tags, or codes, embedded in the text. HTML defines the page layout, fonts and graphic elements as well as the hypertext links to other documents on the Web.
HTML Validation
A program that tests the HTML coding for accuracy and verifies hyperlinks.
Hyperlinks
A predefined linkage between two Internet locations. Web pages may either display the link using text or graphic images.
Hypermedia
The use of data, text, graphics, video and voice as elements in a networked system. All the various forms of information are linked together so that a user can easily move from one to another.
Interactivity
Methods of exchanging information with and engaging visitors to a Web site. These methods range from filling out online forms to sophisticated scripting programs that create dynamic content tailored to the individual visitor.
Internet
A network of networks linking computers worldwide. The Internet is made up of more than 100,000 interconnected networks in over 100 countries, comprised physically of wires, routers, and servers.
ISDN Line
(Integrated Services Digital Network) An international telecommunications standard for transmitting voice, video and data over digital lines running at 64 Kbps (Kilobytes per second).
ISP
(Internet Service Provider) An organization that provides connection services such as Internet access, hosting of Web sites, software for navigating and publishing content on the Internet, and payment systems for electronic commerce.
JAVA
An object-oriented programming language for the Internet, developed by Sun Microsystems, that can be read on any computer platform.
Java applet
A small JavaScript program, such as a utility program or limited-function spreadsheet, which is embedded within an HTML page and executed under a Web browser. Applets can be downloaded as a prepackaged tool for the Web. Some particularly useless Java applets are called "crapplets."
JavaScript
A script language that is easier to use than Java, but not as powerful. JavaScript uses the HTML page as its user interface, whereas Java can generate a completely custom interface. JavaScript does not have the programming overhead of Java, but can be used in conjunction with it. For example, a JavaScript applet could be used to display a data entry form and validate the input, while a Java program processes the information.
JPEG
(Joint Photographic Experts Group) An format for computer graphics, and standard for compressing still images, that is becoming very popular due to its high compression capability. In other words, complex color photographs can be converted to relatively small files to be displayed on the Web.
Log File Parsers
A program that analyzes the records of computer activity, used for statistical purposes.
Megabytes
One million bytes of information. Also MB, Mbyte and M-byte. See also Byte.
Modem
(MOdulator-DEModulator) A device that connects a terminal or computer to a telephone line. It converts the computer's digital pulses into audio frequencies (analog) for the telephone system and converts the frequencies back into pulses at the receiving side. The modem also dials the line, answers the call and controls transmission speed. See also BPS.
Network
The transmission channels interconnecting all client and server stations as well as all supporting hardware and software.
Online
The ability to connect to digital information. Alternately, being available on or logged on to the Internet.
Operating System
The master control program that runs the computer. It is the first program loaded when the computer is turned on.
Pentium Processor
Pentium refers to the Pentium CPU (central processing unit) chip, produced by Intel, that conducts the actual computations within a computer. The Pentium CPU is a microprocessor chip that computes by performing trillions of switch openings and closings. It could also refer to the computer that uses the Pentium CPU.

A database organization method that links files together in order to perform cross-tabulation and queries, resulting in value-added information. Non-relational databases organize information in a flat file structure.
Search Engine
Automated searching programs that send "spider" programs out over the Internet to collect text from Web sites to store in a searchable database. Yahoo!, the first search site to gain world wide attention, actually uses humans to catalogue the information into hierarchical directories by subject.
Secure Sockets Layer (SSL)
An encryption system, developed by Netscape, which automatically encrypts data sent between two remote computers. SSL relies on RC4, a private encryption key method.
