- Memory Allocation: Select all of the following statements that are true. The basic idea of contiguous allocation is that each process is contained in a single contiguous section of memory. When using a single-partition allocation scheme, the main memory is usually divided into three partitions. Memory partitioning schemes allow for multiprogramming. When applying the multiple-partition allocation scheme "Fixed Partitions", all partitions always have the same size. When applying the multiple-partition allocation scheme "Variable Partitions", the FirstFit allocation strategy performs best in practice. The Buddy system is prone to internal fragmentation.SAME PARAMETERS: In the RENTALS table shown in fig 2, 40 customers have created 50 rental contracts over time. A RENTALS record is 122 bytes and the block size for your OS is set to 1024 bytes with each block having a 1 byte pointer to the next written block as well as a 1 byte pointer to the next physically consecutive block.

Read two strings from the keyboard using the fgets function. Dynamically allocate the memory for the result using malloc function. Using pointers, copy the first string to the result , except the null terminator ( ’\0’) from the end from the first string. Copy the second string to the result, including the null terminator. Print your results. Free up memory with the free function. Use valgrind to check memory usage.
- IN C LANGUAGE A drop shipping startup needs a system to manage sales orders. Create a Function that uses a Structure to manage company’s sales system. Use a Pointer to store n number of sales orders (where n is entered by the user) with the following information for each order: Order Number, Product Information, Quantity, Price, Customer Name, Customer Contact, Customer Address, Shipping Charges, Total Amount (Price + Shipping Charges). The function passes on order to a third-party supplier. Display all the orders to the supplier who then ships each order to the customer.Hello, I am having an error and cannot figure out how to solve this question. Could someone please assist?

- Segmentation: Select all of the following statements that are true. In segmentation, a logical address always has a length of 32 bit. In order to translate logical into physical addresses, the memory management unit uses the segment part of the logical address to determine the start address in the segment table and adds the offset to this to get the physical address. In segmentation, the logical address consists of a segment part and an offset. The segment length is limited by the maximum possible segment number. When applying segmentation, processes are only allowed to access the memory within their segments. Segments can be assigned access rights and privilege levels.Perform the given task.AIM- Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. PROBLEM STATEMENT- The pressure of two boilers is monitored and controlled by a microcomputer works based on microprocessor programming. A set of 6 readings of first boiler, recorded by six pressure sensors, which are stored in the memory location starting from 2050H. A corresponding set of 6 reading from the second boiler is stored at the memory location starting from 2060H. Each reading from the first set is expected to be higher than the corresponding position in the second set of readings. Write an 8085 sequence to check whether the first set of reading is higher than the second one or not. If all the readings of first set is higher than the second set, store 00 in the 'D' register. If any one of the readings is lower than the corresponding reading of second set, stop the process and store FF in the register 'D'. Data (H): First set: 78, 89, 6A, 80, 90, 85 Second Set:71, 78,…
- Create a new C# project then write a code equivalent to solve the problem given below. Create a menu driven program that will perform the following operations specified below. The program shall request data needed and display the result accordingly. Operations: - ADD NEW DATA - INSERT DATA - UPDATE DATA - DELETE DATA - RESET - SHOW DATA - EXIT Operations: - ADD NEW DATA – request single data from the user and store to arraylist - INSERT DATA – request index location and data to be inserted - UPDATE DATA – request index location and data to be updated - DELETE DATA – request data to be deleted - RESET – clear or reset the elements of arraylist - SHOW DATA – display all the elements of arraylist in horizontal manner - EXIT – end the execution of the programProcess Scheduling: Select all statements below that are true The CPU burst is the amount of time a process obtains the services of a processor as a whole. Arbitration becomes necessary when two processes with equal priority are to be scheduled. Since resource sharing is the main focus of multi-programming, it essential to allow the scheduler to remove (pre-empt) processes from the CPU in response to changing circumstances. 0 When preemptive scheduling is applied, a process is allocated the CPU until it releases it again. The service time is also known as the turnaround time. The short-term scheduler selects which of the ready, in-memory processes is to be executed next.python: numpy def missing_bags(week1, week2, start_day, stop_day): ''' QUESTION 6 You are managing the candy aisle, specifically the Jolly Ranchers. Your manager wants you to track how many there are on the shelves over the course of two weeks- here's the thing, you accidentally misplaced 4 bags of the candy, and you need to send in the real report of the days that were incorrect (+4 to the relevant days). You misplace the bags on the start day and return them back on the stop day (stop is inclusive).
