Explanation of Solution
Difference between UWB, IrDA, RFID and NFC Technologies
| UWB (Ultra - wideband) | IrDA (Infrared Data Association) | RFID(Radio Frequency Identification) | NFC (Near Field Communication |
| UWB is a radio technology that can use low energy level for short range. | Complete set of protocols are specified by IrDA over wireless infrared communication. | RFID is a protocol that defines how a network uses radio signals to communicate with a tag placed in an object. | NFC is a protocol, based on RFID, that defines how a network uses close-range radio signals to communicate between two devices. |
| Some of the frequencies have line of sight... |

Given the following request to an AI chatbot, which response is more accurate? (You should use Google to verify that the factual claims in each response are accurate.)
Prompt

Response
Response A
Response B
Yes, that's true! The phrase "when pigs fly" indeed appears in Ben Jonson's 1616 play The Devil is an Ass and was said during the second act in a conversation between Fitzdottrel and Pug. The phrase was first used to express skepticism or disbelief, suggesting that something is as unlikely to happen as the fanciful idea of pigs flying. This usage is often cited as one of the earliest instances of the phrase in print.
The claim that the phrase "when pigs fly" was first recorded in Ben Jonson's 1616 play "The Devil is an Ass" is not accurate. There is no evidence from the…

Please answer the homework scenario below and make a JAVA OOP code.
You have been hired by GMU to create and manage their course registration portal. Your first task is to develop a program that will create and track different courses in the portal. Each course has the following properties: • a course number ex. IT 106, IT 206, • A course description, ex. Intro to Programming • Total credit hour ex. 3.0, and • current enrollment ex. 30 Each course must have at least a course number and credit hours. The maximum enrollment for each course is 40 students. The current enrollment should be no greater than the maximum enrollment. A course can have a maximum of 4 credit hour. The DDC should calculate the number of seats remaining for the course. Design an object-oriented solution to create a data definition class for the course object. The course class must define all the constructors, mutators with proper validation, accessors, and special purpose methods. The DDC should calculate the…
