Program Evaluation and Review Technique (PERT): A project management methodology that uses a network diagram to visualize the dependencies and interdependencies of tasks within a project. It is used to estimate the duration of a project and identify potential bottlenecks. Examples include PERT diagrams for software development projects, construction projects, and event planning projects.

Protected Extensible Authentication Protocol (PEAP): Protected Extensible Authentication Protocol (PEAP) is an authentication protocol that encapsulates Extensible Authentication Protocol (EAP) within an encrypted and authenticated Transport Layer Security (TLS) tunnel. It is used to enhance the security of wireless networks and VPNs by ensuring that client credentials are transmitted securely over potentially vulnerable or untrusted networks.

Prototyping: The process of creating a preliminary or working model of a product or system for the purpose of testing and evaluating its design and functionality. This is commonly used in the development of software and hardware products to ensure that the final product meets the desired specifications and requirements. Examples include paper prototypes and beta versions of software products.

Rapid Application Development (RAD): A software development methodology that emphasizes rapid prototyping and iterative feedback over traditional lengthy planning and design phases. It focuses on quickly developing and adapting software solutions using agile techniques and low-code platforms to meet evolving user needs efficiently.

Relational Database Management System (RDBMS): A type of database management system that uses a relational model to organize data into tables and establish relationships between them. Used in database management and data analysis. Examples -MySQL, Microsoft SQL Server, Oracle Database.

Relational database model: A data model that represents data as a set of formally described tables from which data can be accessed or reassembled in various ways without needing to reorganize the tables themselves. This model was conceived by E.F. Codd, and it forms the theoretical basis of relational databases. It uses a standard method to store and retrieve data and is widely used due to its simplicity, flexibility, and efficiency.
