predefined tasks‚ usually with very specific requirements. Since the system is dedicated to specific tasks‚ design engineers can optimize it‚ reducing the size and cost of the product. Embedded systems are often mass-produced‚ benefiting from economies of scale. Personal digital assistants (PDAs) or handheld computers are generally considered embedded devices because of the nature of their hardware design‚ even though they are more expandable in software terms. This line of definition continues to blur

Lecture 1 1.1 INTRODUCTION Data structure is the branch of computer science that unleashes the knowledge of how the data should be organized‚ how the flow of data should be controlled and how a data structure should be designed and implemented to reduce the complexity and increase the efficiency of the algorithm. The theory of structures not only introduces the data structures‚ but also helps to understand and use the concept of abstraction‚ analyze problems step by step and develop algorithms to
