Projector:
Projector is a device used to display the text and images from a computer or mobile device screen on a large screen. With the help of a projector, an audience can see the image clearly.
- For example, projectors are used in many classrooms so that students can view the trainer’s presentation on the screen.
- Some projectors are large devices that are fixed to a ceiling or wall in the presentation hall.

In the past, encryption and decryption were mostly done by substitution and permutation of letters in a text message. study those classic cryptographic schemes Then, develop an automatic cipher using Javascript The cipher should be able to perform the following tasks:
generate keys
encrypt a given plaintext message with a key selected from the list of keys generated
decrypt a given ciphertext message with a known cipher key

- Case Study Instructions: Offshore Wind Energy in the North Sea For this case study, students will analyze the institutional challenges and social rules surrounding offshore wind energy development in the Dutch North Sea, as explored in the case study from the textbook (pages 44-46). 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_forwardAlphabetic 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_forward

Question 15 options: True False Part of the reason that many critics disliked 1950s gameshows was the fact that gameshows offered one of the few opportunities to see unscripted interactions with "real" (average/non-famous) people on television. Question 16 options: True False The Andy Griffith Show is an example of the "rural revival" shows that become enormously popular on 1960s American television. Question 19 options: True False During the Network Era, the hours before primetime each day were exclusively devoted to locally-produced programming, not programming dictated by an affiliate station's parent network.
