 NFC stands for near field communication, which is a wireless communication technology that allows devices to exchange data or perform transactions when they are within a few centimeters of each other. NFC uses radio frequency identification (RFID) to create a short-range wireless connection. NFC is commonly used for contactless payments, smart cards, and digital wallets. References : The Official CompTIA IT Fundamentals (ITF+) Study Guide (FC0-U61), page 174.

Product key licensing is an example of utilizing a personalized code for continuous personal access to a software product. A product key is a unique alphanumeric code that is required to activate or register a software product, such as an operating system or an application. A product key ensures that the user has a legitimate copy of the software and prevents unauthorized use or distribution. Site licensing is a type of licensing that allows an organization to install and use a software product on multiple devices within a specific location, such as a school or a company. Open-source licensing is a type of licensing that allows anyone to access, modify, and distribute the source code of a software product, such as Linux or Apache. Single-use licensing is a type of licensing that allows only one installation and use of a software product, such as a game or an antivirus program. References: CompTIA IT Fundamentals (ITF+) Study Guide: Exam FC0-U61, Second Edition, Chapter 5: Database Fundamentals and Security Concepts, page 175

A database is a collection of data that is organized so that it can be easily accessed, managed, and updated. A database can store different types of data, such as text, audio, video, images, and documents, in a structured way that allows for efficient searching, sorting, filtering, and querying. A database can also enforce rules and constraints on the data to ensure its validity and consistency. A database is best suited to meet the need of a music studio that wants to store artist data as text, demos as MP3 files, and sheet music as PDF files in an organized and easily searchable format, because it can handle the variety, volume, and complexity of the data, and provide fast and accurate retrieval and manipulation of the data. References:
