Questions and Answers

What characterizes a linked list compared to other data structures?

It requires contiguous memory allocation for efficient usage.

Nodes are arranged in a strictly physical sequence.

It consists of a collection of nodes linked logically. (correct)

Memory for all nodes is allocated statically.

In terms of memory allocation, how does a linked list operate?

Memory is allocated only for the first node.

Memory for each node is allocated prior to the list's usage.

Memory is allocated for all nodes at once during initialization.

Memory is allocated for each node at run time. (correct)

Which of the following statements is true regarding the elements of a linked list?

Their sequence is determined by direct memory addresses.

They must be stored in contiguous memory locations.

They must follow a specific order defined by a sorting algorithm.

They do not need to be in a physical sequence. (correct)

Study Notes

Linked Lists

A linked list is a linear data structure that stores a sequence of nodes.
These nodes are connected in a logical order, but their physical location in memory can be non-sequential.
Linked lists are dynamic data structures. This means that memory is allocated for each node during runtime, allowing the list to grow or shrink as needed.
