PARAMETER	ARRAY	LINKED LIST
Define	Array is a collection of elements having same data type with common name.	Linked list is an ordered collection of elements which are connected by links/pointers.
Memory structure	In array, elements are stored in consecutive manner in memory.	In linked list, elements can be stored at any available place as address of node is stored in previous node.
Insertion & Deletion	Insertion & deletion takes more time in array as elements are stored in consecutive memory locations.	Insertion & deletion are fast & easy in linked list as only value of pointer is needed to change.
Memory Allocation	In array, memory is allocated at compile time i.e. Static Memory Allocation	In linked list, memory is allocated at run time i.e. Dynamic Memory Allocation.
Types	Array can be single dimensional, two dimension or multidimensional.	Linked list can be singly, doubly or circular linked list.
Dependency	In array, each element is independent, no connection with previous element or with its location.	In Linked list, location or address of elements is stored in the link part of previous element/node.
