+## Real Life uses of Linked List
+Music Player – Songs in the music player are linked to the previous and next songs. So you can play songs either from starting or ending of the list.
+GPS navigation systems- Linked lists can be used to store and manage a list of locations and routes, allowing users to easily navigate to their desired destination.
+Task Scheduling- Operating systems use linked lists to manage task scheduling, where each process waiting to be executed is represented as a node in the list.
+Speech Recognition-  Speech recognition software uses linked lists to represent the possible phonetic pronunciations of a word, where each possible pronunciation is represented as a node in the list.
