Explanation
An ARM processor is a type of processor that uses a reduced instruction set computer (RISC) architecture, which means it executes fewer and simpler instructions than other types of processors. An ARM processor is designed to be energy-efficient, low-cost, and suitable for mobile devices. A tablet would most likely use an ARM processor because it is a mobile device that needs to conserve battery power and perform basic tasks. A laptop, a workstation, and a server are not devices that would most likely use an ARM processor because they are not mobile devices or they need to perform more complex tasks.

Explanation
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.
