- What is data structure?
Data structure is an entity where data is aligned and organized in a certain way and can be easily manipulated depending on the requirements. A data structure can have numerous data sets.
2. What is a linked list?
A linked list is a sequence of nodes. Each node is normally connected to the next node forming a chain of data storage.
3. In details, explain the process of referencing all the elements in a one-dimension array?
You use an indexed loop to execute from index zero to the array size minus one to refer to all the elements.
4. List one area where data structure is applied?
Data structure is important when handling data and it can be applied in areas like:
- Statistical Analysis
- Numerical Analysis
- Database Management
- Operating Systems
5. Explain the term LIFO?
Last in First Out – The process is used to explain how data is accessed, stored, and retrieved. The latest data to be stored in a database is the first data to be accessed or retrieved.
6. What is a binary tree?
It is a type of data structure that has two nodes, the right and the left node. The binary trees are an extension to the linked list.
7. What is a stack?
A data structure where the top layer element can be accessed. Data gets to be stored in stack and every time a data is stored, it pushes the data downwards enabling the user to access the latest data from the top layers.
8. What is a multidimensional array?
An array that uses multiple indexes in order to store data in the database.
9. Is a linked list considered to be a linear or a non-linear data structure?
A linked list can be considered a linear or a non-linear data structure. For instance, if the linked list is used on storages, then it is considered to be a non-linear data structure. Whereas if the linked list is used against the access strategies then it will be considered as the linear data structure.
10. How does dynamic memory allocation help in data management?
By allocating structures blocks into more flexible composite structures making it easy to expand and contract as need be. Dynamic memory allocation further provides capabilities when it comes to storing simple structures data types.
