Chapter 4, Problem 4RQ

(A) A cellular system has 12 microcells with 10 channels per cell. The microcells are split into 3 microcells, and each microcell is further split into 4 picocells. Determine the number of channels available in system after splitting into picocelles.

Question 8 (10 points) Produce a relational schema diagram that corresponds to the following ER diagram for a Vacation Property Rentals database. Your relational schema diagram should include primary & foreign keys. Upload your relational schema diagram as a PDF document. Don't forget that the relation schemas for "Beach Property" and "Mountain Property" should each have primary keys. FYI: "d" in this notation denotes a subclass.

You are called by your supervisor to go and check a potential data bridge problem. What are the stepsyou will follow in order to check the database and fix any problems with it? Have in mind that youSHOULD normalize it as well.

Modern life has been impacted immensely by computers. Computers have penetrated every aspect of oursociety, either for better or for worse. From supermarket scanners calculating our shopping transactionswhile keeping store inventory; robots that handle highly specialized tasks or even simple human tasks,computers do much more than just computing. But where did all this technology come from and whereis it heading? Does the future look promising or should we worry about computers taking over theworld? Or are they just a necessary evil? Provide three references with your answer.

Objective: 1. Implement a custom Vector class in C++ that manages dynamic memory efficiently. 2. Demonstrate an understanding of the Big Five by managing deep copies, move semantics, and resource cleanup. 3. Explore the performance trade-offs between heap and stack allocation. Task Description: Part 1: Custom Vector Implementation 1. Create a Vector class that manages a dynamically allocated array. 。 Member Variables: ° T✶ data; // Dynamically allocated array for storage. std::size_t size; // Number of elements currently in the vector. std::size_t capacity; // Maximum number of elements before reallocation is required. 2. Implement the following core member functions: Default Constructor: Initialize an empty vector with no allocated storage. 。 Destructor: Free any dynamically allocated memory. 。 Copy Constructor: Perform a deep copy of the data array. 。 Copy Assignment Operator: Free existing resources and perform a deep copy. Move Constructor: Transfer ownership of the data array…

2.68♦♦ Write code for a function with the following prototype: * Mask with least signficant n bits set to 1 * Examples: n = 6 -> 0x3F, n = 17-> 0x1FFFF * Assume 1 <= n <= w int lower_one_mask (int n); Your function should follow the bit-level integer coding rules Be careful of the case n = W.
