Consider the two internal organizations for
heap files (using lists of pages and a directory
of pages) discussed in the text.
1. Describe them briefly and explain the
trade-offs. Which organization would you
choose if records are variable in length?
2. Can you suggest a single page format to
implement both internal file organizations?
Create the programme shuffleSort. It initially checks to determine if the data is correct. If they are, the sort is complete. If not, the data is jumbled and the procedure is repeated. What is the longest possible run time? Is there a maximum running time? What is your reasoning? Would your answer alter if the data were shuffled every time and organised in a never-before-seen configuration?
Suppose a file with 65536 records is organized using multi-level indexing as the file is ordered
on a non-key field. Each record is 48 bytes long and the size of its key field is 4 bytes. The
indexing is built on the key field of the file. The size of the disk block is 2 KB, and the block
pointer size is 12 bytes. The file organization is unspanned. How many blocks will be required
for the inner and outer index respectively in a multi-level index?
512 and 2
b) 512 and 4
e) 1024 and 4
d) 1024 and 8

- For PyTorch and TensorFlow, I try to understand How is the overall file organization on disk for both frameworks? Do they store a bunch of smaller files, a few big files? Where is the metadata kept? Is there one file that has the metadata for the entire dataset/ is the metadata sprinkled in the various files. I appreciate if you can give me a detailed answer.arrow_forwardCompute total no of blocks} Consider a file of 8192 records. Each record is 16 bytes long and its key field Is of size 6 bytes. The file is ordered on a key field, and the file organization is unspanned. The file is stored in a file system with block size 512 bytes, and the size of a block pointer is 10 bytes. If the primary index is built on the key field of the file, and a multilevel index scheme is used to store the primary index, number of first-level and second level blocks in the multilovel index are the respectively 16 and 1 b. 32 and 1 16 and 2 8 and 1 c. d.arrow_forwardObject code files are generated by compilers and assemblers from source code. The object files need to be linked together before they can be executed. Compilers could, in principle, produce executables without linking. Can you explain the problems with the second method?arrow_forward
- Describe the concept of versioning in object serialization. How can versioning be used to handle changes in the structure of serialized objects over time?arrow_forwardThis is a discrete math problem. Please explain each step in detail, no cursive writing.arrow_forwardWrite a C program that implements the parent producer and child consumer algorithms. The parent process must copy an entire source file ("input.txt") to a destination file. In addition, the parent process must produce the file contents into shared memory as read from a source file (SRC_FILE) in chunks using the read() system call. The chunk size (CHUNK_SIZE) is the same for both read() and write(). It will be accepted as input by your program as a command-line argument.arrow_forward
- Explain the concept of versioning in object serialization. How can versioning be handled to maintain compatibility between different versions of serialized objects?arrow_forwardCompilers 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?arrow_forwardWrite an 8086 assembly language program to write a block of 2KB data into an existing file "database.dat". Explain the logic of the program with the algorithm.arrow_forward
- In an executable object file that is in executable and linkable format (ELF), which section defines the addresses of the stack and the heap? A. The data section B. The .text section C. These addresses are not defined in the executable object file. Instead, they are assigned by the operating system when the program is loaded in to me D. These addresses are not defined in the executable object file. Instead, they are assigned by the user when the program is running in memory.
