It's not very difficult but it's quite different than the idea of using an array to access a place in memory. This is the level of sophistication that's not reached by a lot of programmers. Most novice programmers don't get this far. The next element in the sequence each time. And the only thing you can do is get to the next element in the memory.

They're not stored next to one another in memory. So the whole idea is that the size of the structure is variable, is just as many links as you have.

And we're going to work with Java code and then later on we're going to talk more detail about how things are represented in a machine. That's the Java name for the memory address. In Java, these things are called references. So in this case, Alice is linked through the memory address to Bob, and Bob is linked to the memory address to Carol, and Carol's link is null so that indicates the end. In this case, what we have in the computer is a memory address of another object and on the left is the names where the objects are located in the memory, and every object has associated with it, the name of another object in memory. There, we're going to associate with each object a link to a different object. A linked data structure is a different thing. The thing is fixed size, but you can get quickly to any item in there, that's a sequential data structure. And the items are stored one after another consecutively in the memory. The memories have names, and here the names all begin with C. So, here this is pointing ahead a little to a small machine that we're going to talk about in detail later in the course. In your computer's memory they just go consecutively in the memory of the computer. Sequential data structure are an array, we put all the objects right next to one another. So, the idea is a distinction between sequential and linked allocation of memory to hold data. It's a fundamental data structure with all kinds of applications, and that's the one that's going to solve this problem for us. The new data structure that we're going to use to implement stacks and queues, is called a linked list. No certificate will be offered upon completion. The course emphasizes the relationships between applications programming, the theory of computation, real computers, and the field's history and evolution, including the nature of the contributions of Boole, Shannon, Turing, von Neumann, and others.Īll the features of this course are available for free.

We conclude with machine architecture (including machine-language programming and its relationship to coding in Java) and logic design (including a full CPU design built from the ground up). Next, we introduce classic theoretical models that allow us to address fundamental questions about computation, such as computability, universality, and intractability. Our intent is to demystify computation and to build awareness about the substantial intellectual underpinnings and rich history of the field of computer science.įirst, we introduce classic algorithms along with scientific techniques for evaluating performance, in the context of modern applications. It covers the second half of our book Computer Science: An Interdisciplinary Approach (the first half is covered in our Coursera course Computer Science: Programming with a Purpose, to be released in the fall of 2018). This course introduces the broader discipline of computer science to people having basic familiarity with Java programming.
