Basically, an array is a set of similar data objects stored in sequential memory locations under a common heading or a variable name.

While a linked list is a data structure that contains a sequence of the elements where each element is linked to its next element. There are two fields in an element of the linked list. One is the Data field, and the other is the link field, Data field contains the actual value to be stored and processed. Furthermore, the link field holds the address of the next data item in the linked list. The address used to access a particular node is known as a pointer.

Another significant difference between an array and a linked list is that Array has a fixed size and required to be declared prior, but Linked List is not restricted to size and expand and contract during execution. Below is a summarized table showing differences clearly
