URL
Uniform Resource Locator |
An Internet address (for example, http://www.kmkenterprises.com/support/), usually consisting of the access protocol (http), the domain name (www.kmkenterprises.com), and optionally the path to a file or resource. |
HTML
Hypertext Markup Language | Not technically a programming language, HTML is considered a markup language used to structure text and multimedia documents and to set up hypertext links between documents, used extensively on the World Wide Web. |
HTTP
Hypertext Transfer Protocol | A protocol used to request and transmit files, especially webpages and webpage components, over the Internet or other computer network. |
FTP
File Transfer Protocol
| The standard protocol used to transfer files across the Internet, or a similar network, between computer systems. |
POP or POP3
Post Office Protocol (v3)
| A standard interface between an e-mail client program and the mail server. POP3 provides a message store that holds incoming e-mail until users log in and download it. POP3 is a simple system with limited selectivity. All pending messages and attachments are downloaded when users check their mail. |
SMTP
Simple Mail Transfer Protocol | The standard e-mail protocol on the Internet. SMTP defines the message format and the message transfer agent (MTA), which stores and forwards the mail. SMTP servers route SMTP messages throughout the Internet to a mail server that provides a message store for incoming mail. The mail server uses the POP3 or IMAP4 access protocol to communicate with the user's e-mail program. |
IMAP or IMAP4
Internet Message Access Protocol (v4)
| A standard interface between an e-mail client program and the mail server. IMAP4 provides a message store that holds incoming e-mail until users log in and download it. Whereas POP3 downloads the entire message with attachments when mail is checked, IMAP4 can be configured to download only the headers, which display to/from addresses and subject. The user can then selectively download messages and attachments. |
MIME
Multipurpose Internet Mail Extensions | The most common method for transmitting non-text files via Internet e-mail. MIME encodes the files using one of two encoding methods and decodes it back to its original format at the receiving end. A MIME header is added to the file which includes the type of data contained and the encoding method used. |
JPG or JPEG
Joint Photographic Experts Group
| Pronounced "jay-peg," the JPEG format is a standard computer file format for storing graphic images in a compressed form for general use. JPEG images are compressed using a mathematical algorithm. A variety of encoding processes can be used, depending on whether the user's goal is the highest quality of image (lossless) or smallest file size (lossy). JPEGs are not suitable for graphs, charts and explanatory illustrations because the text appears fuzzy, especially at low resolutions. |
GIF
Graphics Interchange Format | Standard computer file format for graphic images. GIF files use data compression to reduce the file size. The original version of the format was developed by CompuServe in 1987. The current version supports animated GIFs (a graphics image that moves). Pronounced "giff" with a hard "g" by most Mac users and "jiff" by PC users, GIFs are widely used on the Web because the format uses its own form of compression. |
PNG
Portable Network Graphics | A bitmapped graphics file format endorsed by the World Wide Web Consortium. It is expected to eventually replace the GIF format, because there are lingering legal problems with GIFs. CompuServe owns the format, and Unisys owns the compression method. In addition, GIF is a very basic graphics format that is limited to 256 colors (8-bit color). PNG provides advanced graphics features such as 48-bit color, including an alpha channel, built-in gamma and color correction, tight compression and the ability to display at one resolution and print at another. |
MPEG
Moving Pictures Experts Group | A standard for compressing digital video. Pronounced "em-peg," it is the universal standard for digital terrestrial, cable and satellite TV, DVDs and digital video recorders (DVRs). |
CGI
Common Gateway Interface | Specification by which a Web server passes data between itself and an application program. Typically, a Web user will make a request of the Web server, which in turn passes the request to a CGI application program. The program processes the request and passes the answer to the server, which in turn sends it to the user. |
Perl
Practical Extraction and Reporting Language | High-level computer programming language, the most popular language for writing CGI scripts and the premier scripting (or interpreted) language of the World Wide Web. Because of its excellent text-processing capability, it is widely used by system administrators (for writing administrative tasks) and is especially suited for developing prototype versions of programs. Because it is an interpreted language, its programs are highly portable across different operating systems. |
PHP
PHP Hypertext Preprocessor | A scripting language used to create dynamic Web pages. With syntax from C, Java and Perl, PHP code is embedded within HTML pages for server side execution. It is commonly used to extract data out of a database and present it on the Web page. |
