What does DLL (library assembly) stand for

shared by executable files and further shared object files (rather than relying on the linker, modules used by the program are loaded from individual shared objects into memory at load time or run time)
what does “load time” accomplish
part of the OS; places programs into memory and prepares them for execution
What was the cause of “dll hell”
many programs running in a single memory space
What does CLI accomplish
specification describing executable code and runtime, allowing for code written in multiple languages on multiple platforms to be run without being rewritten

what is an endpoint
system:system.servicemode:services
provide clients with access to the functionality a Windows Communication Foundation (WCF) service offers
what does ETL stand for
Extract, Transform and Load
via ETL (extracct, Transform, Load) describe each
Extracts data from homogeneous or heterogeneous data sources
Transforms the data for storing it in proper format or structure for querying and analysis purpose
Loads it into the final target (database, more specifically, operational data store, data mart, or data warehouse)
what is abstraction
the process of separating ideas from specific instances of those ideas at work
what does lazy loading accomplish
delays loading of images until they are in the viewport
what does lazy loading accomplish

what does XSLT stand for
Extensible Stylesheet Language Transformation
What does XSLT accomplish
for transforming XML documents into other XML documents, or other formats such as HTML for web pages, plain text or into XSL Formatting Objects, which may subsequently be converted to other formats, such as PDF PostScript and PNG.
The original document is not changed; rather, a new document is created based on the content of an existing on
