+# Data Structure
+
+Data Structure is a way of collecting and organizing data in such a way that we can perform operations on these data in an effective way.
+
+A Data Structure is a named group data of different data types which can be processed as a single unit. A data structure has well-defined operations, behavior and properties.
+
+Different Data Structures are as follows:

+
+### Operations on Data Structures
+
+The basic operations that are performed on data structures are as follows:
+
+* **Insertion:** Insertion means addition of a new data element in a data structure.
+
+* **Deletion:** Deletion means removal of a data element from a data structure if it is found.
+
+* **Searching:** Searching involves searching for the specified data element in a data structure.
+
+* **Traversal:** Traversal of a data structure means processing all the data elements present in it.
+
+* **Sorting:** Arranging data elements of a data structure in a specified order is called sorting.
+
+* **Merging:** Combining elements of two similar data structures to form a new data structure of the same type, is called merging.
