111. TOLL Plaza simulation is an application of ________ .

Correct Answer: B. Queue
Solution:

In the context of data structure applications, а queue is typically used for scenarios requiring first-in, first-out (FIFO) behaviour, such as managing tasks in a service area. A toll plaza simulation, where vehicles are processed in the order they arrive, is a perfect application of the queue data structure.

112. Logistic regression can be binomial, __________ or multinominal.

Correct Answer: A. ordinal
Solution:

Logistic regression can be binomial, ordinal, or multinomial. The correct classification for logistic regression types includes "ordinal," which refers to a type where the categories have a specific order but are not necessarily evenly spaced, fitting well with the concept of ordinal logistic regression where the response variable categories have a meaningful order but unknown spacing.

113. ________ allows you to alter all the slides in the presentation.

Correct Answer: C. Slide master
Solution:

The slide master in presentation software like Microsoft PowerPoint is a feature that allows changes to be made across all slides in a presentation. This includes modifying the layout, background, color, fonts, and other design elements, which ensures consistency throughout the presentation.

114. In python elements of the list are written inside:

Correct Answer: A. [ ]
Solution:

In Python, elements of a list are enclosed in square brackets [ ]. A list is a collection which is ordered and changeable, allowing duplicate members. Lists are used to store multiple items in a single variable.

115. _________ is a drawing object which is usually printed as the background of text on all the pages of document.

Correct Answer: C. Watermark

A watermark in document creation is a recognizable image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), used primarily for security purposes or as a distinguishing characteristic.

116. If data is organized in rows, which function is used to search a value?

Correct Answer: A. HLOOKUP
Solution:

The HLOOKUP function in spreadsheet applications like Microsoft Excel is used to search for a value in the top row of a table or range of cells, and then returns a value in the same column from a specified row. This function is particularly useful when data is organized in rows and the task is to find specific values within those rows.

117. Full form of ASCII is:

Correct Answer: D. American Standard Code for Information Interchange
Solution:

ASCII stands for American Standard Code for Information Interchange. It is a character encoding standard used for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices that use text. Most modern character-encoding schemes are based on ASCII, although they support many additional characters.

118. _________ allows you to synthesize and analyze data from list or existing table.

Correct Answer: D. Pivot table
Solution:

A pivot table is a data summarization tool commonly used in data visualization and reporting. It automatically sorts, counts, totals, or gives the average of the data stored in one table or spreadsheet and displays the result in a second table showing the summarized data. Pivot tables are a crucial tool for data analysis in spreadsheet programs.

119. _________ command is used to duplicate the active document under different names?

Correct Answer: A. File-Save as
Solution:

The "File-Save As" command in computer applications is used to save the current document or file with a different name or in a different location.
