Connected lists are an information structure that is dynamic, assigning the needed storage when the program is started.
Deletion and insertion node operations are often executed in a linked list.
Linear data structures for example stacks and queues are often executed with a linked list.
They might expand in real time without memory expense and can reduce access time.
Disadvantages:

They've a tendency to squander memory as a result of pointers needing additional space for storing.
Nodes in a linked list should be read from the beginning as linked lists are fundamentally sequential access.
Nodes are stored incontiguously, considerably increasing the period required to obtain individual elements within the list.
Issues arise in linked lists with regards to reverse crossing. Singly linked lists are extremely hard to navigate backwards, and memory is wasted in allocating space for a rear pointer, while doubly linked lists are rather easier to study.
