Q221.
What method is used in video compression to store only the differences between successive frames?

a.

Huffman encoding

b.

Run-length encoding

c.

Differencing methods

d.

Fractal compression

Discuss
Answer: (c).Differencing methods Explanation:Video compression uses differencing methods to compute the difference between successive frames and then store only this difference. This takes advantage of the fact that successive frames are often similar, reducing the amount of data that needs to be stored.
Q222.
Which compression technique is especially good for textured features in images?

a.

Huffman encoding

b.

Run-length encoding

c.

Differencing methods

d.

Fractal compression

Discuss
Answer: (d).Fractal compression Explanation:Fractal compression is especially good for textured features in images. It refers to any image that contains parts which, when suitably scaled, are similar to the whole. Fractal compression can store these self-similar parts with only a few numeric parameters, making it effective for compressing textured images.
Q223.
What is the basic standard for text storage?

a.

UNICODE

b.

ASCII

c.

RTF

d.

SGML

Discuss
Answer: (b).ASCII Explanation:The basic standard for text storage is the ASCII (American standard code for information interchange) character codes. It assigns internationally recognized 7-bit codes (decimal values 0-127) to standard printable characters and control characters.
Q224.
Which format is commonly used for storing structured text in an extensible way?

a.

UNICODE

b.

ASCII

c.

RTF

d.

SGML

Discuss
Answer: (d).SGML Explanation:SGML (Standard Generalized Markup Language) is commonly used for storing structured text in an extensible way. It allows users to define their own structures for documents and provides a flexible approach to organizing and storing data.
Q225.
Why is there a wide range of formats for bitmap storage?

a.

Bitmaps require a large amount of storage space

b.

Bitmaps include a variety of image sizes and color maps

c.

Bitmaps often have complex formatting information

d.

Bitmaps use different character encoding schemes

Discuss
Answer: (b).Bitmaps include a variety of image sizes and color maps Explanation:Bitmaps need to record various information, such as the size of the image, the number of bits per pixel, color maps, and the image itself. In addition, an icon may have a "hot-spot" for use as a cursor. Due to the different ways of encoding these features and the potential combinations of these encodings, there is a wide range of formats for bitmap storage.
Q226.
What is a common shared format for storing formatted text?

a.

UNICODE

b.

ASCII

c.

RTF

d.

SGML

Discuss
Answer: (c).RTF Explanation:Rich Text Format (RTF) is a common shared format for storing formatted text. It encodes formatting information, including style sheets, and can be used to transfer documents between different applications. However, it may represent a simplified version of the full document style.
Q227.
What is a valid reason for not indexing on too many items in a database?

a.

It adds to the size of the database, increasing storage cost.

b.

It reduces the efficiency of search algorithms.

c.

It hinders the ability to find records given partial information.

d.

It compromises the security and privacy of the data.

Discuss
Answer: (d).It compromises the security and privacy of the data. Explanation:One valid reason for not indexing on too many items in a database is to protect the privacy and security of the data. For example, certain sensitive information may be indexed for internal use but not divulged to the general public to ensure customer privacy.
Q228.
What is Soundex used for?

a.

To protect the privacy of customer information in telephone directories.

b.

To index words, especially names, based on their sound similarity.

c.

To quickly scan a list of files for specific words.

d.

To allow users to find records given partial information.

Discuss
Answer: (b).To index words, especially names, based on their sound similarity. Explanation:Soundex is a way of indexing words, especially names, based on their sound similarity. It allows the system to find words that sound similar to the given key, even if they are misspelled.
Q229.
What is the main characteristic of free text retrieval systems?

a.

They allow long passages of text to be stored in records.

b.

They rely on special key fields with associated indexes.

c.

They use structured text for storage.

d.

They center on unformatted, unstructured text and create word indices.

Discuss
Answer: (d).They center on unformatted, unstructured text and create word indices. Explanation:The main characteristic of free text retrieval systems is that they center on unformatted, unstructured text and create word indices. These systems keep an index of every word in every document, allowing users to search for documents containing specific words or phrases.
Q230.
What are the advantages of using compression techniques for storing data?

a.

Compression reduces the need for multiple storage formats.

b.

Compression ensures data integrity and prevents data loss.

c.

Compression reduces the transfer time for large files.

d.

Compression increases the capacity of storage devices.

Discuss
Answer: (c).Compression reduces the transfer time for large files. Explanation:One of the advantages of using compression techniques for storing data is that it reduces the size of files, which in turn reduces the transfer time for large files over networks or storage devices.
