Expert Solution & Answer

Chapter 9, Problem 61CRP

a.

Explanation of Solution

Advantage of a sequential file over an indexed file:

In sequential file, the data or records is stored in the serial manner. So, the following operation will be fast.

Searching records

The binary search is implemented on sorted records. Hence, this operation will be fast.

Updating records

Here also, the binary search is implemented. Hence, this operation will be fast.

Deleting records

Searching the records is fast in this operation.

In sequential file, the records are sorted on the value of one or more fields...

b.

Explanation of Solution

Advantage of a sequential file over a hash file:

For accessing the record from the sequential file, direct key or record number can be specified but in hash file, hash function is needed to solve.

A hash function is computed on some attribute of each record. It identifies the record location to be positioned.

The sequential file is used to read or write a flat sequential file whereas hash file is used to read or write a hash file.

In sequential file, the records will be loaded generally whereas in hash file, the data is loaded based on hash algorithm...

c.

Explanation of Solution

Advantage of an indexed file over a sequential file:

In indexed file organization, the records address are stored in distinct file and their data is accessed by using pointers.

Therefore, the record is accessed by less time while in sequential file the searching starts from first record until the record is found in key database...

d.

Explanation of Solution

Advantage of an indexed file over a hash file:

In indexed file, the index records take less time to access when comparing with hash file.

Indexing offers comparatively fast access to entries within a data storage structure but hash file takes more time to access the entries...

e.

Explanation of Solution

Advantage of a hash file over a sequential file:

Comparing with sequential file, the hash file is more secured and takes less time to access records...

f.

Explanation of Solution

Advantage of a hash file over an indexed file:

In index file, file index is generally stored as a distinct file on the similar storage device.

Then the index is transferred to main me...

We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure. Alice's public key (n,public_key) is (247,7). A code breaker manages to factories 247 = 13 x 19 Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.

Consider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks? Justify your answer.
