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.
Addressing and Address Binding: Select all of the following statements that are true. Direct addressing means that the address to be accessed is located elsewhere. Relocatable code must be generated if the memory location to be used is not known at compile time. Relative addressing means that the address to be accessed is specified as a distance from a reference address. Absolute addressing means that the address to be accessed is specified completely and without other reference addresses. Address binding is not possible during execution time. The logical address space is bound to a separate physical address space.
The address operator O is a variable that holds an address all of these O returns the memory address of a variable dereferences a pointer and allows access to the value of the variable the pointer points to

Local addresses The "A1" address system has coordinates that exist over the whole worksheet. If you have a block of data specified somewhere within that worksheet, it can be useful to be able to specify the addresses relative to that block. This can be done with INDEX(), which takes 3 arguments. The first argument is a rectangular range of data, for example A2:E8. The second and third arguments are numbers specifying an offset down then right from the top left of that data range. Unlike OFFSET(), the numbering starts at 1, so INDEX(A2:E8, 4, 2) refers to cell B5. Instructions Use the block of data for North East India + North Myanmar, from A11 to G19 as the reference. In cell I1, use INDEX() to get the number of Blues in Sikkim. In cell I2, get the number of White-yellows in Mizoram Hills. please show the formulas in excel thank you :) Area Locality Skipper Swallowtail White-yellow Blue Brush-footed Blues in Sikkim Indian Subcontinent Indian Subcontinent 307 94 99…
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.
Assembly language Part 1: When a variable is stored in memory, it is associated with an address. To obtain the address of a variable, the & operator can be used. Write a C program addressOfScalar.c by inserting the code below in the main function. Questions: 1) Run the C program, attach a screenshot of the output in the answer sheet. 2) Attach the source code in the answer sheet 3) Then explain why the address after intvar is incremented by 4 bytes instead of 1 byte.
PuTTY/Ocelot Assignment #2 Instructions: (using C language in the UNIX environment, Systems Programming) Through this programming assignment, the students will learn to do the following: Usage: mortgagepmt [-s] -r rate [-d downpayment] price In this assignment, you are asked to perform a mortgage payment calculation. All information needed for this will be passed to the program on the command line. There will be no user input during the execution of the program You will need a few pieces of information. The price of the home and the amount of the down payment. You will also need to know the interest rate and the term of the mortgage. To figure your mortgage payment, start by converting your annual interest rate to a monthly interest rate by dividing by 12. Next, add 1 to the monthly rate. Third, multiply the number of years in the term of the mortgage by 12 to calculate the number of monthly payments you'll make. Fourth, raise the result of 1 plus the monthly rate to the…
Instructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only. Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum Example data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1 Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.
