Operations Security (OPSEC): A systematic process for identifying, controlling, and protecting sensitive information in an organization's operations. It is used to prevent unauthorized disclosure of information that could be exploited by adversaries. Examples of OPSEC measures include encrypting communications and restricting access to sensitive data.

Operator Console: A terminal or interface from which operators can monitor and manage the state of a system, network, or process. The console provides a comprehensive view of the operation, typically in real-time, and often includes tools for troubleshooting, management, and configuration of components within the system.

Optical Character Recognition (OCR): A technology that enables the conversion of different types of documents, such as scanned paper documents, PDF files, or images captured by a digital camera, into editable and searchable data. This is commonly used in digital archiving, where physical documents are converted into digital formats for easier data retrieval and management.

Optical Scanner: A device that converts images, printed text, handwriting, or an object into a digital image. It's widely used to digitize physical photographs and documents so they can be edited, stored, and shared electronically. Its usage plays a crucial role in maintaining digital records and reducing paper clutter.

Organization for Economic Cooperation and Development (OECD): An international organization that works to build better policies for better lives. Their goal is to shape policies that foster prosperity, equality, opportunity, and well-being for all. They draw on almost 60 years of experience and insights to better prepare the world of tomorrow.
