In the sorting phase, chunks of data small enough to fit in main memory are read, sorted, and written out to a temporary file. Merge sort first divides the array into equal halves and then combines them in a sorted manner. To do this requires competence in principles 1, 2, and 3. Following terms are the foundation terms of a data structure. Data structure can be defined as the group of data elements which provides an efficient way of storing and organising data in the computer so that it can be used efficiently. This page will contain some of the complex and advanced data structures like disjoint. Merge sort is a divideandconquer algorithm based on the idea of breaking down a list into several sublists until each sublist consists of a single element and merging those sublists in a manner that results into a sorted list. Divide means breaking a problem into many small sub problems. Quick sort algorithm is fast, requires less space but it is not a stable search.

Linked list is a very commonly used linear data structure which consists of group of nodes in a sequence each node holds its own data and the address of the next node hence forming a chain like structure linked lists are used to create trees and graphs. Algorithms, on the other hand, are used to manipulate the data contained in these data.
