A decision tree is a graphical representation that depicts a hierarchy of independent conditions and the corresponding activities that occur based on the valid combination of these conditions. It allows for the visualization of different possible outcomes and paths based on the evaluation of certain conditions. Each condition acts as a branch in the tree, leading to different activities or actions depending on whether the condition is true or false. This hierarchical structure helps in understanding the flow of decisions and actions in a systematic and organized manner.Rate this question:

What is an algorithm used for?
- A.
Governing the transformation of input data flows into output data flows
- B.
Dislpaying one or more sets of actions that are executed based on the state of the conditions (true or false)
- C.
Outlining the final solutions that you must translate into a specific programming language with syntactical structures
- D.
Portraying a hierarchy of independent conditions and the activities resulting form each valid combination of conditions
Correct Answer
C. Outlining the final solutions that you must translate into a specific programming language with syntactical structuresExplanation
An algorithm is used to outline the final solutions that need to be translated into a specific programming language with syntactical structures. It provides a step-by-step plan or set of instructions for solving a problem or completing a task. The algorithm acts as a blueprint for the implementation of the solution in a programming language, ensuring that the solution is accurately and efficiently executed.Rate this question:

What are reserved words?
- A.
Algorithms written in structured English
- B.
Words you can pass using specific parameters
- C.
Algorithms and syntax used in a particular programming language
- D.
Words having special meaning to a particular programming language
Correct Answer
D. Words having special meaning to a particular programming languageExplanation
Reserved words are words that have a special meaning in a specific programming language. These words are reserved by the language and cannot be used for any other purpose, such as variable names or function names. They are typically used to define the syntax and structure of the language, and using them for any other purpose would result in a syntax error. Examples of reserved words in programming languages include "if", "while", "for", "int", "float", etc. These words are essential for writing code that follows the rules and conventions of the language.Rate this question:

What is an iterative primitive solution?
- A.
Step-by-step processing
- B.
A hierarchy of independent conditions
- C.
Code structured for repetitive execution
- D.
Alternative steps that may or may not be executed
Correct Answer
C. Code structured for repetitive executionExplanation
An iterative primitive solution refers to a code structure that is designed for repetitive execution. It involves using loops or iterations to perform a certain set of instructions repeatedly until a specific condition is met. This approach allows for efficient processing of tasks that require repetitive actions, as it eliminates the need for writing the same code multiple times. By structuring the code in this way, it becomes easier to manage and maintain, leading to more efficient and scalable solutions.Rate this question:

Data items arranged in the order in which they were stored and the same manner that they will be addressed describes the use of a/an
- A.
Linked list
- B.
Ordered list
- C.
Networkd list
- D.
Hierarchical list
Correct Answer
B. Ordered listExplanation
An ordered list is a data structure in which the data items are arranged in the order they were stored and will be addressed. This means that the elements are stored sequentially and accessed in a specific order. Unlike a linked list, an ordered list does not require any pointers or references to connect the elements. It provides efficient searching and retrieval of elements based on their position in the list. Therefore, an ordered list is the most suitable choice for the given description.Rate this question:

A tree sturcutre is best used to display database records that have what type of fields?
- A.
Repetitive
- B.
Duplicate
- C.
Indexed
- D.
Pointer
Correct Answer
A. RepetitiveExplanation
A tree structure is best used to display database records that have repetitive fields. This is because a tree structure allows for efficient organization and retrieval of data that has repetitive patterns. Each node in the tree represents a record, and the branches represent the repetitive fields within that record. This allows for easy navigation and searching of the database, especially when there are multiple occurrences of the same field value.Rate this question:
