- Consider the following code snippet in C: char *base_url = malloc(11 * sizeof(char)); printf("Enter an 11 character URL: "); scanf("%s", base_url); char src[11]; char dst[11]; // copies base_url to src strncpy(src, base_url, 11); // copies src to dest strcpy(dst, src); printf("src: %s dst: %s\n", src, dst); Identify at least one potential buffer overflow vulnerability and explain why/how it can be exploited (i.e., not just that it’s a buffer overflow, but where the problem will manifest itself).18.10 Briefly explain the concept of linked allocation, noncontiguous file storage. For a file that is stored in blocks 5, 12, 13, 14, 19, 77, and 90, show what a linked allocation might look like.A file has r=30,000 EMPLOYEE records of fixed-length. Consider a disk with block size B=512 bytes. A block pointer is P=6 bytes long and a record pointer is P R =7 bytes long. Each record has the following fields: NAME (30 bytes), SSN (9 bytes), DEPARTMENTCODE (9 bytes), ADDRESS (40 bytes), PHONE (9 bytes), BIRTHDATE (8 bytes), SEX (1 byte), JOBCODE (4 bytes), SALARY (4 bytes, real number). An additional byte is used as a deletion marker. a) Calculate the record size R in bytes. b) Calculate the blocking factor bfr and the number of file blocks b assuming an unspanned organization. c) Suppose the file is ordered by the key field SSN and we want to construct a primary index on SSN. Calculate the index blocking factor bfr i.

Give an example where a malloc()-like allocator would fail due to external fragmentation. 2. Give an example where returning a block to the allocator results in reducing the number of free blocks. Assume an implicit free list is used.1. In indexed file allocation method, assuming that the block can only store 8 pointers as shown in the figure (see attached file) , what happens if the file needs 10 pointers? Give the advantages and disadvantages of this method. 2. What could be the advantage/s and disadvantage/s of using the following free space management schemes: a. Grouping b. Counting
- Assume that each block has B = 1000 Bytes, and the buffer pool has m = 1001 frames. What is theexact size of the largest file external memory sorting can sort within 3 passes, i.e., pass 0 to pass 2with pass 2 producing only 1 run?(T/F) In dynamic relocation, the base and bounds values are part of the process state. (Y/N) In base and bounds addressing, can the base and bounds values for a process change during the lifetime of a process? If a process attempts to access a memory location outside its own virtual address space, what is the result? 1) a trap 2) an exception (T/F) A user process can change its own base and bounds values. Suppose we are using base and bounds addressing. If the virtual address is 5321, the base register value is 100, and the bounds register value is 4500, then what is the corresponding physical address. (The values given are decimal values.)Write a C code to perform vector arithmetic: Define 3 vectors A[100], B[100], C[100]. Get n from as a command line argument. Example if n=10, then (./vector 10), and create n processes. (n will be one of Divisors of 100). Get operation from user: add, sub. Each process will create a number of threads. Number of threads per process = 100/(10 number of processes). Perform the operation on a chunk of the vector, for example, if n = 10, each process will create (100/10*10=1) 1 thread to add\sub 10 elements. Use execl to run the add or sub programs Parent should print A.B.C in a file. (yourname.txt) For example, n=5, operation sub Partition work equally to each process: PO create (100/10*5=2) 2 threads → Thread00 will executes A[0:9] B[0:9]-C [0:9] = Thread01 will executes A[10:19] B[10:19]-C[10:19] = PI create (100/10*5=2) 2 threads → Thread 10 will executes A[20:29] = B[20:29]-C [20:29] Thread11 will executes A[30:39] B[30:39]- C[30:39] = and so on. no…
- With linked allocation, each file is a linked list of disk blocks; the disk blocks may be scattered anywhereon the disk. The directory contains a pointer to the first and last blocks of the file.
