LAMP (Linux/Apache/MySQL/PHP) is a popular Open Source Website platform combination of Operating System (Linux), Web server (Apache), database (MySQL) and scripting language (PHP).
Local Area Network. A network that connects computers in a small pre-determined area (like a room, a building, or a set of buildings). LAN’s can also be connected to each other via telephone lines or radio waves. Workstations and personal computers in an office are commonly connected to each other with a LAN. This allows them to have send/receive files and/or have access to the files and data. Each computer connected to a LAN is called a node.
A landing page is the page where a visitor first enters a website. Oftentimes, a special landing page is created to elicit a specific action from the new visitor (usually in connection with an advertising or marketing campaign).
1) time it takes for a data packet to move across a network connection; 2) visible delay between request and display of content and ad. Latency sometimes leads to the user leaving the site prior to the opportunity to see. In streaming media, latency can create stream degradation if it causes the packets, which must be received and played in order, to arrive out of order.
The vertical spacing between lines of text.
A link farm is any website setup specifically to increase the link popularity of other websites by increasing the number of incoming links to that site. While some link farms are single pages listing unrelated links, others consist of networks of sites that contain multiple links back and forth to one another. Search engines can generally recognize these types of schemes and often remove link farms from their directories and penalize the sites linking to and from them.
An element in an electronic document that links to another place in the same document or to an entirely different document. Typically, you click on the hyperlink to follow the link. Hyperlinks are the most essential ingredient of all hypertext systems, including the World Wide Web.
An Open Source computing platform based on the robust core of commercial Unix systems. Developed by a Finnish programmer named Linus Torvalds in the early 90's, the Linux core is typically distributed with hundreds of other 'packages', commonly known as GNU/Linux. There are dozens of popular distributions (or 'flavours') of GNU/Linux such as the popular RedHat, Mandrake, Slackware and Debian. GNU/Linux is become popular because it is free, flexible and secure.
A liquid layout is one that is based on percentages of the browser window’s size. The layout of the site will change with the width of the browser, even if the visitor changes their browser size while viewing the page. Liquid layouts take full advantage of a person’s browser width, optimizing the amount of content you can fit onscreen at one time.
"Localhost" is an alias for the address 127.0.0.1, an address that always indicates the local computer. This is the address that a computer can use to refer to itself. For example, when testing a Web application on the same computer as the server, you can use the address http://127.0.0.1 or http://localhost.
A file that records transactions that have occurred on the Web server. Some of the types of data which are collected are: date/time stamp, URL served, IP address of requestor, status code of request, user agent string, previous URL of requestor, etc. Use of the extended log file format is preferable.
In graphic design, lossless compression refers to a data compression technique where the file quality is preserved and no data is lost. Lossy compression, by contrast, eliminates some data can further decrease file size.
A term coined by graphics programmers to refer to a technique of shrinking file sizes by giving away some precision of detail. JPEG is an example of a file that is compressed this way. By reducing the so-called quality of a picture when you save it, you can make the file size smaller. Many photos can take of loss of fine detail before it becomes noticeable on a web page.
