DLP

In terms of "data loss prevention" DLP is a computer security term referring to systems that identify, monitor, and protect data in use (e.g., endpoint actions), data in motion (e.g., network actions), and data at rest (e.g., data storage). DLP systems are designed to detect and prevent the unauthorized use and transmission of confidential information. 

In regards to "digital light processing" DLP refers to microprojections that are tiny but at a short range they give you a nearly cinematic experience. Digital Light Processing (DLP) is a trademark owned by Texas Instruments, representing a technology used in some TVs and video projectors. It was originally developed in 1987 by Dr. Larry Hornbeck of Texas Instruments, and became one of the leading technologies used in digital cinema projection.
