Explanation
Large retailers use a process known as data mining to study trends. Data mining involves analyzing large sets of data to discover patterns, relationships, and insights that can be used to make informed business decisions. By examining customer behavior, purchasing patterns, and market trends, retailers can identify opportunities for growth, improve inventory management, and enhance customer satisfaction. Data mining helps retailers understand consumer preferences, predict future trends, and develop effective marketing strategies. It is a valuable tool for retailers to gain a competitive advantage in the market.

Explanation
Point-of-sale (POS) terminals, formerly known as cash registers, are often connected to complex inventory and sales computer systems. This means that when a transaction is made at the POS terminal, it can update the inventory in real-time and provide accurate sales data. This connectivity allows businesses to track inventory levels, monitor sales trends, and generate reports for better decision-making. POS terminals also streamline the checkout process by automating calculations and providing various payment options for customers. Overall, the use of POS terminals improves efficiency and accuracy in sales and inventory management.

Explanation
A PSS (Portable Shopping System) is a small, wireless handheld computer that scans an item's tag and pulls up the current price (and any special offers) as you shop.

Explanation
Computer forensics is a law enforcement specialty that involves the recovery and analysis of digital evidence from computers or other digital devices. This includes the ability to recover and read deleted or damaged files from a criminal's computer. Computer forensics experts use specialized tools and techniques to collect, preserve, and analyze digital evidence in order to support criminal investigations and legal proceedings.

Explanation
Analyzing the data or information is not one of the four major data processing functions of a computer. The four major data processing functions are gathering data, processing data into information, and storing the data or information. Analyzing the data or information involves examining and interpreting the processed data to derive meaningful insights or make informed decisions, which is a separate step beyond the basic data processing functions.

Explanation
RFID tags, when placed on an animal, can be used to record and track in a database all of the animal's movements. RFID stands for Radio Frequency Identification, and it uses radio waves to transmit data between the tag and a reader. The tag contains a unique identifier that can be associated with the animal's information in a database. This allows for efficient and accurate tracking of the animal's movements, making it a suitable technology for this purpose.

Explanation
Robotic technology allows surgeons to perform delicate operations by manipulating devices through computers instead of manually. This technology enables precise and controlled movements, reducing the risk of human error and allowing for minimally invasive procedures. Robotic surgery has revolutionized the field of medicine, offering improved surgical outcomes, shorter recovery times, and less scarring for patients.

Explanation
When technology is no longer protected by copyright and is available to everyone, it is considered to be in the public domain. However, the given answer states that it is "proprietary," which is incorrect. Proprietary refers to technology that is privately owned and protected by intellectual property rights, such as patents or trademarks.

Explanation
Nanoscience is the study of molecules and structures that have a size ranging from 1 to 100 nanometers. This field focuses on understanding and manipulating materials at the nanoscale, which has unique properties and behaviors compared to bulk materials. Nanoscience has applications in various fields, including medicine, electronics, energy, and materials science. It involves the study of nanoparticles, nanomaterials, nanotechnology, and their interactions with different systems.

Explanation
Artificial intelligence (AI) is the correct answer because it is the science that aims to develop machines capable of exhibiting human-like intelligence. AI involves creating computer systems that can perform tasks that would typically require human intelligence, such as problem-solving, learning, and decision-making. It encompasses various techniques and approaches, including machine learning, natural language processing, and computer vision, among others, to enable machines to mimic human cognitive abilities. AI has applications in various fields, including robotics, healthcare, finance, and transportation, and continues to advance rapidly in recent years.
