This paper reviews the different ways of building data in computer systems, or aspiring to the data structure, as well as the searching methods in this data, which is known as algorithms. Data Structures and algorithms are integrated to form computer programs and in broader terms, explains what is generally known as programming abstraction.
Data structures discuss the ways and mechanisms that we use to organize data in an integrated form in computers systems and exploitation of memory locations in an easy and structured ways such as arrays, stacks, queues, lists, linked lists and other. Algorithms, on the other hand, are the ways in which the instructions and operations are carried out to handle information and data on the different types of data structure.

Chapter Summaries
1. Introduction: This chapter introduces the concepts of data and data structures, highlighting their importance in organizing and managing information. It emphasizes the relationship between data structures and algorithms, explaining how they work together to solve problems efficiently. The chapter also defines data structures, contrasting them with the raw data they organize. Examples are provided to illustrate the practical application of organizing data using structures like arrays, strings, and records to tackle complex informational challenges. The chapter concludes by stating the paper's objectives of exploring various data structures and algorithms.
2. Abstract Data Types (ADTs): This chapter focuses on Abstract Data Types (ADTs), defining them as mathematical models for data structures with similar behaviors. It explains the importance of ADTs in software development, emphasizing their role in simplifying complex data handling. The chapter highlights the concept of abstraction, the process of creating a model to define a problem before tackling the implementation details. The discussion expands on the benefits of using composition and abstraction in software development, showcasing how it facilitates efficient, understandable, and easily modifiable code by separating concerns and abstracting away implementation details. Common ADTs like sets, trees, stacks, queues, and heaps are mentioned as examples. The chapter also explores the difference between abstract data types and their concrete implementations.
3. Data structures: This chapter delves into the concept of data structures as the physical implementation of ADTs. It classifies data structures into three main types: linear, tree, and graph. The chapter then focuses on linear data structures, discussing arrays, strings, records, tables, lists, stacks, and queues. A detailed explanation of one-dimensional arrays is provided, using student scores as an example. The chapter shows how to define and use arrays in Java, including how to access and manipulate elements within the array using indexing.
