Advances in computing technology which allow for a faster hash rate will provide faster transactions per second.   True ◻ False ◻

Create hash table and an appropriate hash function for use in storage and retrieval of character data. You will vary the size of the table and count the number of collisions that occurs with each table. Includes the following basic methods: init - mark all positions of the table as empty. hashMe - calculate the hash index based on properties of the data. getNextOpenPosition - in the event of a collision, search table for the next available piece of memory. showTable - prints out occupied positions in table. rehash - when collisions become frequent, allocate a new table with a larger size and then rehash the data from the current table into the new table using a hash function that is modified to take the new table's size into account. The Hashing function is: hashKey = function of data characteristics a) Create a hash table. Use your table to “sort” a list of names. A list of test names are below: joe bob harry mary brian tom jerry bullwinkle pam ellis dale bill barrack george gertrude…

Q6: If the password contains 3 different lowercase letters and its hash is "ae8e7blef9bf9fbd07770b1d60e62d27" based on MD5. Find the original password.

Q4: Based on MD5 hash algorithm, if we used 31 blocks and the padding size is 24 bytes. Find the message size. Q5: The password may contain UPPERCASE, lowercase, octal numbers, and following special characters "&, ?, %, #" find total possible combination number of password that contains 8 non repeated characters.

In your initial post, describe the function of hashing tools you can use to verify that two files are identical. For example, you can compare the hash value of a file on a website with the hash value of that file after you download it. If the hash values match, you downloaded the unmodified version of the website file. Research and discuss at least two examples other than the one provided.

The hash key of the value 30 in the following hash table is: 2 3 4 7 8 18 2 93 13 30 24 88 53 O 5 O Error O 6 O 3 O None of them

Question 2 and explain how you can tell it was manipulated thanks!

Mr. Akbar is senior software developer working on an ecommerce website he wants to add the following products on his website with following keys Mouse Keyboard 5882 Cable Webcam Monitor 4614 6713 4409 1825 To make searching better he asked his junior to find the 2 digit hash address of products by following techniques and share results with him a) Division method with m-97 b) Mid square method c) Folding method without reversing d) Folding method with reversing Question-3 (b) Consider your name, take ASCII value of each character and map all those values in a Hash table using division method. Mention each insertion step wise and if there is collision, mention that as well. Answer the following questions A) What should be the preferable Table size and why? B) What technique did you use to cater collision and why? C) What is the value of load factor D) Implement the above problem in java using generic hash function class

Insert the following data to an initially empty hash table with a size of 19. ALONGDATASTRINGFORTHEQUESTION Which cells remain empty when separate chaining is applied? O 2-9- 10 – 12 – 15 O 3- 10 - 11 – 13 - 16 O 4-11 - 12 - 14 – 17 O No empty cells
