Question:
Which of the following is not a non linear data structure ?
Which of the following is not a non linear data structure ?
Show Hint
Non-linear = Branching (Trees, Graphs). Linear = Straight line (Arrays, Lists).
Updated On: Jun 6, 2026
- Binary tree
- Heap
- Graph
- char
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Data structures are classified based on how elements are organized and accessed.
1. Non-Linear Data Structures:
In these structures, data is not organized in a sequential or linear fashion. Elements can be connected to multiple other elements.
• Trees (Binary tree, Heaps): Hierarchical structures.
• Graphs: Networks of nodes and edges. 2. Linear Data Structures: Data is organized sequentially. Examples include Arrays, Linked Lists, Stacks, and Queues. 3. Analyzing "char": The term char is a primitive data type, not a complex data structure. However, in the context of this question's classification, a single character variable does not have the branching or hierarchical properties of trees or graphs. Among the choices, it is the only one that is not a non-linear organization of data.

- Choose the correct answer from the options given below:
(A). RAID 3 requires only a single redundant disk.
(B) In RAID 4 scheme, two different parity calculations are carried out and stored in separate blocks on different disks.
(C) RAID 5 distributes the parity strips across all disks.
(D) In RAID 2, the number of redundant disks are proportional to the log of the number of data disks. - In case of DMA, after the completion of the transfer, the processor is required to be notified of the completion. This is done through.
