what are data structures and why are they important ?

In every day life we do certain job by implementing a strategy and  plan so then only we could live a pleasant life that doesn't ruin our routines .
what are the algorithm we follow in real life , they are best-shortest-path strategy to take a quickest road,Divide and Conquer as a business strategy to handle employers with manager and managers from different department,stack(what we eat doesn't comes out through mouth at end of the day),queue structure to buy a ticket and several more...

Similarly computers do follow a strategy  where in the real world they are as follows:-
windows media player playlist follows queues.
Computer memory follows stack structure.
Rip is a networking protocol that uses distance vector routing protocol.
arrays follows linked list.
windows search follows searching algorithms.
Fb also uses Data structures traversal,search,reorder algorithms.
and several more.....
