Term explanation
Closed questions are questions that can be answered with a limited set of responses — most commonly a simple 'yes' or 'no', or a selection from predefined options. They are used to gather specific, factual information quickly and efficiently. In presentations and training settings, closed questions are useful for gauging audience understanding, confirming agreement, or running quick polls. While efficient, they offer little depth and should be balanced with open-ended questions when richer feedback or discussion is needed.
LIZ AI helps structure presentations around the questions that matter. The Smart Presentation Composer frames content with clear, focused messaging — making it easier for audiences to follow arguments and reach conclusions.

It defines a standardized way for AI agents to connect to external tools, data sources, and enterprise systems — without requiring custom integrations for every connection. MCP acts as a universal interface: an AI agent with MCP support can securely access databases, APIs, document repositories, and business applications using a consistent protocol, regardless of the underlying system. This dramatically simplifies how AI is embedded into complex enterprise environments.

Learn moreA .pps file is a legacy PowerPoint slideshow format that opens directly in presentation mode rather than the editing view. Double-clicking a .pps file launches the slideshow immediately, which made it popular for distributing finished presentations to audiences. The .pps format was later replaced by .ppsx as part of Office 2007's shift to an open XML-based file structure.
Learn moreAn e-lecture is a recorded or live-streamed lecture delivered digitally, typically as video content that learners can watch on any device. E-lectures replicate the structure of traditional academic lectures but remove geographic and scheduling constraints. They are common in university distance learning programs, corporate training platforms, and MOOCs. E-lectures are often paired with supplementary materials, quizzes, or discussion forums to maintain engagement and assess comprehension.
