- Explain the concept of object-oriented programming (OOP) and discuss its advantages in software development. Choose the correct statement regarding the advantages of object-oriented programming: A) OOP promotes code reusability and modularity but does not support encapsulation. B) OOP encourages procedural programming techniques and reduces code organization complexity. C) OOP facilitates code maintenance and enhances scalability by allowing easier modification and extension. D) OOP primarily focuses on optimizing memory usage and does not offer support for inheritance.Memory Hierarchy and Caches (thank you for the help) 1. This works under the principle that if an item was recently accessed from memory, those items that have an address close by will have a high probability of also being referenced soon. a) Temporal Locality b) Principle of Locality c) Memory Hierarchy d) Spatial Locality 2. A program only accesses a relatively small portion of their address space at any instant of time. a) Temporal Locality b) Principle of Locality c) Memory Hierarchy d) Spatial Locality 3. Utilizes multiple levels of memory with different speeds and sizes. a) Temporal Locality b) Principle of Locality c) Memory Hierarchy d) Spatial Locality 4. This works under the principle that if something was recently accessed in memory then it is most likely to be accessed again soon. a) Temporal Locality b) Principle of Locality c) Memory Hierarchy d) Spatial Locality 5. Even though looping instructions and the data used by the loops are likely to be accessed…you wrote a software simulation of a computer that executes programs written in Simpletron Machine Language (SML). In this exercise, we propose several modifications and enhancements to the Simpletron Simulator. In Exercises 19.30–19.34, we propose building a compiler that converts programs written in a high-level programming language (a variation of BASIC) to SML. Some of the following modifications and enhancements may be required to execute the programs produced by the compiler. [Note: Some modifications may conflict with others and therefore must be done separately.] Allow the simulator to perform exponentiation calculations. This requires an additional Simpletron Machine Language instruction.

- Task Description: Section A - SELECT ONLY ONE TASK TO IMPLEMENT FROM THIS SECTION 1) TopChoice Car Leasing Company (TCL) provides services of car leasing to employees of various organisations in the form of salary packaging. Employees have the choice of leasing a vehicle for a fixed amount under a flexible lease term and the cost of vehicle leasing can be deducted from the employee's pay check. At the end of each year of the lease term, employee can make an offer to purchase the leased vehicle based on the residual value of the vehicle after depreciation. There are two types of vehicles available for lease, sedan and SUV. TCL depreciates sedan by a 10% rate and SUV vehicles are depreciated at a 11% rate. Hence, they need a depreciation calculator. For instance, a sedan vehicle worth $25,000 will be valued at only $16,402.50 in 4 years. For a SUV vehicle worth $45,000, the depreciated value will be $28,234.01 in 4 years. You are to write a program to calculate a depreciation schedule…System Description Data Dictionary (Description of each table and attribute) Conceptual Model (Entity/Relationship Model) Logic Model (Relational Model) Database Schema Script (DDL). 3.5 A dentist’s office needs to keep information about patients, the number of visits they make to the office, work that must be performed, procedures performed during visits, charges and payments for treatment, and laboratory supplies and services. Assume there is only one dentist, so there is no need to store information about the dentist in the database. There are several hundred patients. Patients make many visits, and the database should store information about the services performed during each visit and the charges for each of the services. There is a standard list of charges, kept outside the database. The office uses three dental laboratories that provide supplies and services, such as fabricating dentures. Draw a complete E-R diagram for this example158. Concerns related to task synchronization or memory management is a. systemic b. functions c. properties d. tolerance
- For each of the following, choose the most suitable data structure(s) and explain the reason briefly. a) Customer servicing on first come first served basis. b) A text-editing program requires remembering the operations it performed in opposite order. c) A printer serving multiple users. d) A scoreboard keeping the scores of the top 10 players in a tournament.Assume the memory contains 6 holes with the sizes of 190, 550, 220, 420, 650, and 110 A sequence of requests for 4 blocks is to be satisifed: A = 210, B = 430, C = 100, D = 420. The following table has two rows for each of the four memory allocation strategies (first fit, next fit, best fit, worst fit). Fill in the table as follows: Block Allocated: Enter the letter of the memory block that will be placed in the indicated hole. If more than one block is allocated in a hole, include both blocks with no spaces (e.g. "DG"). If no block is allocated in a hile, enter "-". • Remaining Size: Enter the size of the remaining hole after all four memory blocks are placed. H1: 190 H2: 550 H3: 220 H4: 420 H5: 650 H6: 110 Block First Fit Blank 1 Blank 2 Blank 3 Blank 4 Blank 5 Blank 6 Allocated Remaining Blank 7 Blank 8 Blank 9 Blank 10 Blank 11 Blank 12 Size Block Next Fit Blank 13 Blank 14 Blank 15 Blank 16 Blank 17 Blank 18 Allocated Remaining Blank 19 Blank 20 Blank 21 Blank 22 Blank 23 Blank 24…1. Computerization of Health Records (70) (((Write a C program))) about A health care issue that has been in the news lately is the computerization of health records. This possibility is being approached cautiously because of sensitive privacy and security concerns, among others. Computerizing health records could make it easier for patients to share their health profiles and histories among their various health care professionals. This could improve the quality of health care, help avoid drug conflicts and erroneous drug prescriptions, reduce costs and in emergencies could save lives. In this exercise, you'll design a "starter" HealthProfile structure for a person. o The structure's members should include: • The person's first name • Last name Gender • Date of birth (consisting of separate attributes for the month, day and year of birth), • Height (in cm) Weight (in pound). o Your program should have a function that receives this data and uses it to set the members of a HealthProfile…
