So these data types are the key to everything right? What are they, exactly?įirst of all, note that programs manipulate information, and information in a program is represented with entities. Alan Kay, The Early History of Smalltalkĭata types combine data entities (units units of information) together with the algorithms that define the behaviors of these entities. Why not thousands of them, each simulating a useful structure? Why not divide it up into little computers, as time sharing was starting to? But not in dozens.

Choosing the wrong algorithms and data structures makes a program slow at best and unmaintainable and insecure at worst.Įxpressed more powerfully: Bob Barton, the main designer of the B5000 and a professor at Utah had said in one of his talks a few days earlier: 'The basic principle of recursive design is to make the parts have the same power as the whole.' For the first time I thought of the whole as the entire computer and wondered why anyone would want to divide it up into weaker things called data structures and procedures.

For systems to be economical, the data must be organized (into data structures) in such a way as to support efficient manipulation (by algorithms).

Computing systems are concerned with the storage and retrieval of information.

In the table above, data structures and algorithms were mentioned together.

Knowledge of data structures and algorithms is essential to gaining any sort of proficiency in nearly every one of the other topics in this table!Įxercise: Wait, that table was kind of neat, right? Computer Science has something for everyone! Which of the topics above sounds like it might interest you? Data Structures and Algorithms is not “just another topic.” It is one of the most central and important topics in all of Computer Science.

They are presented here for reference only-please don’t try to memorize this table! In the breakdown, Data Structures and Algorithms appears as a single, tiny topic:Īlgorithms and Complexity AL Algorithmic Analysis Īrchitecture and Organization AR Digital Logic and Digital Systems Welcome to the study of data structures and algorithms, a discipline within Computer Science.Ī while ago, the ACM created a taxonomy of Computer Science, identifying eighteen knowledge areas. Today will just be a preview of what is to come. We wish to get a sense of what is meant by the terms “algorithm” and “data structure,” why the associated topics are so important in computer science, and what sorts of things make up the study of these fields.
