    What is the simplest type of data structure? - ProProfs

    What is the simplest type of data structure?

    • Multiple arrayy

    • Square array 

    • Simultaneous array 

    • Linear array

    Correct Answer
    A. Linear array
    Explanation
    A linear array is the simplest type of data structure because it consists of a sequence of elements where each element has a unique position. It is a one-dimensional structure where elements are accessed sequentially. Unlike other types of arrays, a linear array does not have any specific pattern or arrangement, making it the most basic and straightforward data structure.

    What is another name for an array index?  - ProProfs

    What is another name for an array index? 

    • Term

    • Piece 

    • Key 

    • Point 

    Correct Answer
    A. Key 
    Explanation
    Another name for an array index is a "key". In programming, an array is a data structure that stores a collection of elements, and each element is accessed using its index or key. The key serves as a unique identifier for each element in the array, allowing for efficient retrieval and manipulation of data. Therefore, "key" is the correct answer as it accurately represents the role of an array index.

    What collection's is an array made up of?

    • Elements 

    • Units 

    • Wares 

    • Data

    Correct Answer
    A. Elements 
    Explanation
    An array is made up of elements.

    Which of these terms is used in naming an array? - ProProfs

    Which of these terms is used in naming an array?

    • Vector 

    • Parasite 

    • Pin

    • Pest

    Correct Answer
    A. Vector 
    Explanation
    The term "Vector" is used in naming an array. In computer programming, a vector is a data structure that represents a collection of elements of the same type. It is commonly used to store and manipulate arrays of data. Therefore, "Vector" is the correct answer for this question.

    Which of these formulas is used in computing index tuple? - ProProfs

    Which of these formulas is used in computing index tuple?

    • Biological 

    • Electrical 

    • Chemical 

    • Mathematical 

    Correct Answer
    A. Mathematical 
    Explanation
    The correct answer is Mathematical. Mathematical formulas are used in computing index tuples, which are typically used in data indexing and retrieval systems. These formulas help determine the position or index of a specific data item within a data structure, such as an array or a database table. By using mathematical calculations, index tuples can efficiently locate and retrieve data, making them an essential component in various computer science and information retrieval applications.

    What are two-dimensional arrays called? - ProProfs

    What are two-dimensional arrays called?

    • Duo 

    • Doubles 

    • Matrices 

    • Matrix 

    Correct Answer
    A. Matrices 
    Explanation
    Two-dimensional arrays are called matrices. Matrices are a type of data structure that store elements in a two-dimensional grid-like format, with rows and columns. They are often used in mathematics and computer science to represent and manipulate data that has multiple dimensions.

    Which mathematical concept's can be used as a two-dimensional grid?   - ProProfs

    Which mathematical concept's can be used as a two-dimensional grid?  

    • Matrix 

    • Logarithm

    • Differentiation 

    • Calculus 

    Correct Answer
    A. Matrix 
    Explanation
    Matrices can be used as a two-dimensional grid because they are arrays of numbers or variables arranged in rows and columns. Each element in the matrix can be accessed by its row and column index. Matrices are commonly used in various areas of mathematics, such as linear algebra and graph theory, as well as in computer science and physics. They are useful for representing and solving systems of linear equations, performing transformations, and organizing data in a structured way.

    What is another name for linear array? - ProProfs

    What is another name for linear array?

    • Squared array 

    • Three-dimensional array 

    • Two-dimensional array 

    • One-dimensional array 

    Correct Answer
    A. One-dimensional array 
    Explanation
    A linear array is another name for a one-dimensional array. It is called "linear" because it consists of a single line or sequence of elements, where each element can be accessed using a single index value. Unlike two-dimensional or three-dimensional arrays, which have multiple dimensions or levels, a one-dimensional array is a simple and straightforward data structure that stores elements in a linear fashion.
