16 Questions
What is the common goal of all data structures?
Efficiently organizing and storing data.
What is the fundamental concept behind the implementation of data structures?
Efficiently fetching and storing data using memory addresses.
How are array and record data structures based on computing the addresses of data items?
Through arithmetic operations.
What is the basis for linked data structures?
Storing addresses of data items within the structure itself.
What is the theoretical concept motivated by the efficiency of data structure operations?
Abstract data type.
What is an array in the context of data structures?
A number of elements in a specific order, typically of the same type.
What is the principal advantage of a linked list over an array?
Efficiently inserting and removing values without relocating the rest of the list.
What is the typical allocation for elements of arrays?
Contiguous memory words.
What is a record in the context of data structures?
An aggregate data structure that contains other values.
What is the term used for a linear collection of data elements where each node points to the next node?
Linked list
What is a data structure in computer science?
A data structure is a data organization, management, and storage format chosen for efficient access to data.
What is an abstract data type (ADT) and how does it relate to data structures?
An abstract data type (ADT) defines the logical form of the data type, while the data structure implements the physical form of the data type.
Give an example of a specialized data structure and its application.
Relational databases commonly use B-tree indexes for data retrieval, while compiler implementations usually use hash tables to look up identifiers.
How do data structures contribute to managing large amounts of data efficiently?
Data structures provide a means to manage large amounts of data efficiently for uses such as large databases and internet indexing services.
Why are efficient data structures key to designing efficient algorithms?
Efficient data structures are key to designing efficient algorithms because they provide a means to manage large amounts of data efficiently.
What do some formal design methods and programming languages emphasize as the key organizing factor in software design?
Some formal design methods and programming languages emphasize data structures, rather than algorithms, as the key organizing factor in software design.
