If every element in a DS has almost two adjacent neighbors then it is called a linear DS. . . Hence doubly linked list is a linear DS

To check if a DS is linear or not just do a simple test . . . check if the data elements of the given DS can be accessed in a sequential manner, if it can, then its a linear DS.

A doubly linked list can be accessed in a sequential manner, hence it is a linear linked list.

Although you have to deal with the complexity but you curb many problems that the users may experience. For eg. imagine how much data is stored in the servers of facebook. . .its massive . . .and ye...

complexity is at the user side in understanding not for the compiler.

data structure is a way of organising and using the memory effectively and efficiently.

It is called conditioning. This question is actually related to electronics and you can find it in "Telecommunication Networks".

type casting.

your qtn itself has the answer.. wen insertion is restricted to one end, then it obviously has to be input restricted dequeue..:)

a.input-restricted queue.

Yes each entry in a link list is called node and this node consist of two parts-info, and next add.

True

Linear data structure is such that they are contiguous either by their arrangement in successive memory locations or by means of pointers. To help you understand it better, let say you were given a bo...

Linear data structures are in which all the data are arranged in sequence manner.for example:linked list,stack queue
Non linear data structure are in which all the data are arranged in random manner.for example :trees,graphs.
