____________terminals (formerly known as cash registers) are often connected to complex inventory and sales computer systems

Data
Point-of-sale (POS)
Sales
Query

Correct Answer

A. Point-of-sale (POS)

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.

____________ tags, when placed on an animal, can be used to record and track in a database all of the animalâ€™s movements.

POS
RFID
PPS
GPS

Correct Answer

A. RFID

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.

Which of the following is NOT one of the four major data processing functions of a computer?

Gathering data
Processing data into information
Analyzing the data or information
Storing the data or information

Correct Answer

A. Analyzing the data or information

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.
