Provide an overview of the three most important file structure approaches.
Step by step
Solved in 2 steps
- Give Advantages of using pointers in file organization as compare to sequential file organization.Name a few of the drawbacks of traditional file-processing systems.Discuss the various file allocation methods used in file systems, such as contiguous allocation, linked allocation, and indexed allocation, highlighting their pros and cons.
- An inquiry has been carried out in order to discover the circumstances that gave rise to the hierarchical organization of the file space.Why is an overflow block utilized in sequential file organization when there is only one overflow record at the moment?Give some instances of the disadvantages of conventional file processing.
- What is the impact of a "log-based" file system?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 8Give an explanation as to why programmers are the primary target audience for file specification books and why it is essential to have them.
- JSON and CSV are both text-based formats for the storage of data. It's possible to open either one in a plain text editor. Given this similarity, why does a CSV file usually take less memory than a JSON formatted file for the same data? Under what conditions could a JSON file be smaller in memory than a cSV file for the same data?What comes to mind when you hear the word "data abstraction"? How can a file be broken down into its parts using the different tools that are available?Give some instances of the disadvantages of traditional file processing.
