Suppose your system has a memory of size 100 MB using contiguous memory allocations and there are 4 fixed size partitions. Partition one of size 50, partition 2 of size 200, partition 3 of size 100 and partition 4 of size 150 Consider First 5 letters of your name. The ASCII code of the letters is the size of process and the alphabet is the name of process. The processes appear in alphabetical order. Q= How many processes will be loaded in the memory at a time? For contiguous memory allocation show the algorithms used to allocate memory partitions to each process and state which algorithm will work best and why? Also state the amount of internal and external fragmentation for the processes and partitions after allocation NOTE :MY NAME IS ALIZAHID
Read the description of the memory configuration and analyze the given diagram. Then, answer the following questions. If you are to add a new 10MB process in the memory, where could it possibly be added and why? What could be the size of the free block just before it was partitioned by X? Rationalize answer.
Given memory partitions of 100K, 600K, 400K, 500K, and 300K (inorder), howwould each of the First-fit, Best-fit, and Worst-fitalgorithms place processes of 117K, 412K, 325K, and 510K (inorder)?

Is it feasible to differentiate between the many types of dynamic memory allocation and allocators and to explain how they work?
Last solution had mistakes: For these questions, assume that memory partitions can be subdivided; multiple processes may fit in a partition if there is room. For example, if we had a 30-MB partition and a 20-MB process that fits in the partition, the partition’s new size is 10 MB after placing the process in it. If a second, 8-MB process arrives, we may place it in the partition, leaving 2 MB free in the partition. (The original memory partition then contains a 10-MB and an 8-MB process.) Consider a swapping system where memory has partitions of the following sizes: 180 MB, 100 MB, 40 MB, 200 MB, 300 MB, and 150 MB (in order). For first fit, how are processes of sizes 180 MB, 30 MB, 150 MB, 80 MB, 100 MB, and 70 MB placed (in order)? Indicate which requests (if any) cannot be satisfied. Repeat question (a) for best fit. Repeat question (a) for worst fit.
When it comes to the distribution of memory, just how does the process of dynamic memory allocation work?Is it feasible to differentiate between the many types of dynamic memory allocation and allocators and to explain how they work?
Create a memory mapping from the cache memory of 512 MB to the main memory of 4 GB using the four-way set associative approach with a block size of 1 MB. Consider that each memory location may be accessed using a byte address.
If you are to add a new 10MB process in the memory, where could it possibly be added and why? What could be the size of the free block just before it was partitioned by X? Rationalize your answer. Would you suggest the provisioning of virtual memory in this configuration? Why or why not? Is it possible to add a new 7MB process using the first-fit placement algorithm without swapping out any process? Why or why not? A new process is requesting a 3MB Illustrate the possible memory configuration using a horizontal segmented memory strip (like the diagram above), where a partition will be created for the new process under the following placement algorithms: best-fit and first-fit. Label your illustration clearly.
Write the C program to solve the question Memory management is the functionality of an operating system which handles or manages primary memory and moves processes back and forth between main memory and disk during execution. Memory management keeps track of each and every memory location, regardless of either it is allocated to some process or it is free. Given five memory partitions of 110 KB, 450 KB, 100 KB, 250 KB, and 500 KB (in order), how would each of the first-fit, best-fit, and worst-fit algorithms place processes of 212 KB, 417 KB, 112 KB, and 426 KB (in order)?Which algorithm makes the most efficient use of memory? Write a program to compare and justify your answer.
A disk has a capacity of two tera-byte size. Say the file system uses a multi-level inode structure for locating the data blocks of afile.The inode stores pointers to data blocks, including a single indirect block, a double indirect block, and several direct blocks in the 64 B of available space.Now, it is given that the disk has a block size of 512 B. The maximum file size that can be stored in such a file system in MB (round off upto 2 decimal places).
Consider a demand-paged computer system where the degree of multiprogramming is currently fixed at seven. The system was recently measured to determine utilization of the CPU and the paging disk. Three alternative results are shown below. For each case, what is happening? Can the degree of multiprogramming be increased to increase the CPU utilization? Is the paging helping? Justify.a.
