- 1. What are the different techniques to remove fragmentation in case of multiprogramming with variable and fixed partitions? DiscussTurn on the Non-executable Stack Protection Operating systems used to allow executable stacks, but this has now changed: In Ubuntu OS, the binary images of programs (and shared libraries) must declare whether they require executable stacks or not, i.e., they need to mark a field in the program header. Kernel or dynamic linker uses this marking to decide whether to make the stack of this running program executable or non-executable. This marking is done automatically by the gcc, which by default makes stack non-executable. We can specifically make it nonexecutable using the "-z noexecstack" flag in the compilation. In our previous tasks, we used "-z execstack" to make stacks executable. In this task, we will make the stack non-executable. We will do this experiment in the shellcode folder. The callshellcode program puts a copy of shellcode on the stack, and then executes the code from the stack. Please recompile call shellcode.c into a32.out and a64.out, without the "-z execstack"…What key aspect of both the binary search and the merge sort accounts for the logarithmic portion of their respective Big Os?
- Question: The purpose of this project is to design and implement a distributed storage system. The system's architecture is inspired bythe abstract architecture for distributed file systems. Among the components, we have a client and multiple instances of a server. We adopt an asynchronous peer-to-peerreplication among the server instances with a replication factor of three. The system supports two operations: read and writeobjects. Each object is represented in a JSON format and stored in a local file for each instance of the server. Note that the fileshave a limited size of 30 MB. As well each object has a key (a string) attached to it. Finally, we use Kafka as a middlewarebetween the client and the server(s) To write an object, the JSON content and the key are sent to the server through Kafka. When the write operation succeeds, theclient receives an acknowledgement from each server. A write operation with an existing key replaces the existing object.Moreover, the client sends a…What are the main advantages of using thread pools in high-concurrency applications?The UNIX kernel will dynamically grow a process's stack in virtual memory as needed, but it will never try to shrink it. Consider the case in which a program calls a C subroutine that allocates a local array on the stack that consumes 10K. The kernel will expand the stack segment to accommodate it. When the subroutine returns, the stack pointer is adjusted and this space could be released by the kernel, but it is not released. Explain why it would be possible to shrink the stack at this point and why the UNIX kernel does not shrink it.
- Discuss the trade-offs between using arrays and linked lists for dynamic data storage.Suppose that you have a very simple file system (VSFS) using i-node to manage disk data blocks, where the disk block size is 4096 bytes. Disk addresses and file block pointers take 32 bits (4 bytes), and the i-node contains 10 direct pointers, one single-indirect pointer and one double-indirect pointer. Assume an index block is the same size as a data block (both 4096 Bytes). If there is a file having 45,000 bytes of data and it has never been accessed, we only assume the file's i-node is in memory, but none of the rest of the file. If the user process wants to read the entire file into the memory, how many disk blocks (including both data blocks and index block(s)) would be brought into the main memory? O a. 11 O b. 10 O C. 12 O d. 1035 e. 1034Compilers and Assemblers translate each source file individually to generate object code files. Hence the object files need to be linked together before they can be executed. Theoretically, however, it is possible to skip the linking step and directly have compilers generate the final executable file. What would be the down side of taking the latter approach?
- Investigate how race conditions can be avoided by using a mutex and locks, as well as other thread management techniques in C++.What is the difference between user-level and kernel-level threading?In what situations is one kind better than the other?Compilers and Assemblers build object code files by translating each source file one at a time. As a result, running the object files requires linking them together first. However, it is theoretically feasible to bypass the linking stage and simply build the final executable file from the compilers. What would be the drawbacks of the second option?
