Linked lists are dynamic linear data containers.
They are linear because each item has one adjacent item in each direction (there is a predecessor, or none, and a successor, or none, to each item, but never more than one in each direction).
They are dynamic because the size is not generally fixed and potentially infinite. To manage such a dynamic structure, memory for new items is allocated at runtime, and the different items are connected, or linked, through pointers.
In a single linked list, a single pointer points from one item to the next item.
In a double linked list, one pointer points from one item to the next item, and a second pointer points to the previous item in the list.

What is a linked list used for?
A linked list is used in computer science to store data as a series of related nodes. Linked lists are used as the basis for abstract data types when programming. The chief advantage of a linked list is that data can be added or removed from the list without having to reorganize the whole list. A drawback to linked lists can be that it is difficult to sort, organize, or recall specific information from the list.
How the pointer used in the linked list?
The pointer in linked list is used for traversing through the elements of the linked list. In a singly linked list, only a next pointer exits. So this pointer can be used for traversing only in one direction in the list. In case of a doubly linked list, a next and previous pointer exits. These pointers are used for traversing in both direction in the list.
Convert single linked list to double linked list?
You copy a singly linked list into a doubly linked list by iterating over the singly linked list and, for each element, calling the doubly linked list insert function.
What is difference between linked list and singly linked list?
Answersingly linked list has the node inserted only at one end. and the pointer corresponds to the next pointer.but in a doubly linked list, the node pointer points to the both previous and the next node.singly linked list has two nodesdoubly linked list has three nodesA doubly linked list makes sense when you need to traverse the list in both directions. You aren't able to do that with a singly linked list.
What is the difference between linked list and Ordinary list?
A list is an abstract data structure, usually defined as an ordered collection of data. A linked list refers to a specific implementation of a list in which each element in the list is connected (linked) to the next element.

Where linked list using?
linked list are used for creation of stack,queues to use memory in optimum manner linked list are used as they are dynamic in nature

So this pointer can be used for traversing only in one direction in the list. In case of a doubly linked list, a next and previous pointer exits. These pointers are used for traversing in both direction in the list.
What is heterogeneous linked list?
Heterogeneous Linked List is a linked list data-structure that contains or is capable of storing data for different datatypes.void pointer is basically used in these types of linked list as we are not sure of which type of data needs to be stored
Convert single linked list to double linked list?

What is a link list in terms of computer science?
in computer science a linked list is a data structure consisting of group of nodes which together represent a sequence. under the simplest from each nod
What is the difference between doubly linked list and circular linked list?
A doubly linked list is a linked list in which each node knows where both of its neighbors are.A circular linked list is a linked list in which the "tail" of the list is linked to the "root". (Note that both the tail and root of the list are undefined/arbitrary in a circular linked list)Doubly linked lists are actually not necessarily related to circular linked list (aside from both being based on a linked list structure). In fact, you can have a circular doubly linked list, where each node knows where both of its neighbors are andwhere the list wraps around to connect to itself.
How many linked list are used in data structure?
How many apples are used in fruit.
Which is the easy insertion operator single linked-list or double-linked list?
It is easier to insert into a singly linked list.
What is the difference between linked list and Ordinary list?
A list is an abstract data structure, usually defined as an ordered collection of data. A linked list refers to a specific implementation of a list in which each element in the list is connected (linked) to the next element.
Explain the linked list and multi linked list structures?
I tried my best to explain all Linked List. For Single Linked List http://www.fansonnote.com/2012/02/single-linked-list/ For Double Linked List http://www.fansonnote.com/2012/02/double-linked-list/ For Multi Linked List http://www.fansonnote.com/2012/02/multi-linked-list/ Hope it will help. Thanks.
