- 166. A unit of storage that can store one or more records in a hash file organization is denoted as a. Buckets b. Disk pages c. Blocks d. Nodes167. The file organization which allows us to read records that would satisfy the join condition by using one block read is a. Heap file organization b. Sequential file organization c. Clustering file organization d. Hash file organizationPassword Cracking Each student should be able to access* one PassXX.hash file. This file contains 4 unsalted md5 password hashes (md5 is commonly used for hashing passwords, though it is a bit weak for modern use. It is very important to salt passwords before hashing them, since leaving them unsalted makes them easier to crack. However, many sites fail to do this). Your assignment is to use Hashcat (or another password cracking or password "recovery" tool) to retrieve the original passwords from the hashes, and submit the password/hash pairs. Each set of hashes contains 1 very easy password and 3 slightly challenging passwords of differing format. Link to hashcat: https://hashcat.net/hashcat/ Note: You will also need one or more dictionaries to perform a dictionary attack. *access: Files are accessible based on your last name. You should see a large number of files that are not accessible due to your account having a wrong last name, and one file that is accessible that lacks…
- 1. A hashing function converts a large ___ to a small ___. 2. A ___ occurs when two keys hash to the same address. 3. For an open hashing scheme, the records within each bucket are stored in key order ( true / false ). 4.

- Given 10,000 URL visit records, design a hashing-based method so that we can quickly retrieve URLS that are most frequently visited. Describe your design concerns in a txt file. Like how you would design the data structure and how you plan to process input and generate output. For instance, your input is a file containing 10,000 rows, where each row contains: URLaddress,visit_timestamp Note that one URLaddress can be visited multiple times.2 Hashing for URL Retrieval: Given 10,000 URL visit records, design a hashing-based method so that we can quickly retrieve URLS that are most frequently visited. Describe your design concerns in a txt file. Like how you would design the data structure and how you plan to process input and generate output. For instance, your input is a file containing 10,000 rows, where each row contains: URLaddress,visit_timestamp Note that one URLaddress can be visited multiple times.81. The process of finding some other position when hash address is occupied is classified as a. collision resolution b. address space resolution c. multiple hashing resolution d. chaining resolution
- The purpose of this project is to assess your ability to: Implement a hash table Utilize a hash table to efficiently locate data Analyze and compare algorithms for efficiency using Big-O notation For this project, you will implement a hash table and use it to store words in a large text file. Your hash table should use chaining for collision resolution. You may design any hash function you wish. Your program will read a file and insert each word into a hash table. Once the table is populated, allow the user to enter words to search for. For each word entered, your program should report the number of elements inspected and whether or not the word was located. Provide an analysis of your insert and search algorithms using Big-O notation. Be sure to provide justification for your claims.Code in JAVA please: Choose one of the following hashing technique and one hashing resolution technique to demonstrate hashing technique. You are required to use array of objects with minimum three data field. Your program should include the following options: - Add a new record. Search for a record. List all the records. Hashing Techniques: Pseudorandom + quadratic probingClose the virtual machines now and close the virtual box.
