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... |

Additional resources in this week’s learning module will provide further perspectives on the impact of wind energy on different stakeholders. Students should refer to the syllabus for specific guidelines regarding length, format, and content requirements. Reflection Questions to Consider: What are the key institutional challenges in implementing offshore wind energy in the North Sea? How do formal and informal social rules shape the use of this shared space? What conflicts arise between different stakeholders (e.g., fishermen, naval transport, military, and wind energy developers)? How can policymakers balance economic, environmental, and social considerations when allocating space for wind energy?…arrow_forward
- Alphabetic Telephone Number TranslatorMany companies use telephone numbers like 555-GET-FOOD so the number is easier for their customers to remember. On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Write a program that asks the user to enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663.arrow_forwardI would like help to resolve the following casearrow_forward7.
