LAMP - An acronym referring to a Web server solution consisting of Linux (operating system), Apache (Web server), MySQL (database), and PHP or occasionally PERL or Python (programing language).

Latency - A time delay between the moment an event is initiated, and when it actually occurs. In the context of digital multi-platform publishing, the concept of latency refers to the delay between the creation of content and its accessibility via a given platform.

By way of example, scraping content from Quark/InDesign layouts and manually creating a Web version (e.g. through a CMS) has much greater latency than simply creating the content in a central repository that can feed both the Quark/InDesign file and the Web content management system. The central repository has 'near-zero' latency as minimal effort is required to repurpose the content across different platforms.

Lossless - An adjective describing an image file compression scheme that reduces file size, without discarding image data. It is important to preserve valuable image data for future uses that often include different sizes and outputs than originally anticipated.

Lossy - An adjective describing an image file compression scheme that reduces file size, but in a way that discards image data. Lossy compression reduces the value of an image file by limiting options for future outputs.
