Computer Science Essentials: Data Structures

Improve your data handling and organisation knowledge by learning the fundamentals of data structure.

Colourful blocks are lined up in a bar chart formation in a pink and green room.

Develop core organisational skills needed for a career in software development

Efficient data organisation is vital when handling large amounts of data, particularly within large organisations.

On this course, you’ll delve into data structure processes, improving your data handling skills and boosting your career prospects in data and development sectors.

Reinforce your understanding of data structures using the key concepts of memory and logarithms

Before diving into data structure, you’ll explore Big O notation, memory, and logarithms, ensuring you have the foundational knowledge to understand in-depth data structure applications.

By applying this theory, you’ll be equipped to assess code base complexity and improve project delivery estimates.

Examine different data types, including linear data structure and primitive data structure

Data can be grouped into primitive or non-primitive data structures and a working knowledge of both will give you the edge against less experienced candidates at interview.

You’ll discover the features of both types of data and learn the operations within linear and non-linear structures.

By understanding this terminology, you’ll be able to easily scale your work up to handle big data and provide solutions within large organisations.

Learn common operations in data structures, from linked lists to stack and queue

Data structure is a cornerstone of a developer’s coding knowledge, improving your understanding of code and helping you create solutions to complex data problems.

You’ll explore common operations including arrays, hash tables, heaps, and graphs, learning how to apply them in real-world scenarios.

By the end of this course, you’ll have improved your problem-solving approach using data structures and also have the skills to demonstrate a deep understanding of complex coding issues in various contexts.

Skip to 0 minutes and 1 second SPEAKER: Don’t let data structures get you down. Learn all the essential computer science skills and watch real life scenarios to learn what you need to know. Follow Shubham Sarda, software developer and digital marketer from Unwired Learning as he demonstrates why he’s an expert in the field. After completing this course, you’ll be able to identify various data structures, apply algorithms, explore logarithms and memory, and do a complexity analysis. And you can do it all wherever and whenever you want. Step into your future with computer science essentials, data structures from Packt and FutureLearn.
