a.3 data structures & representation
Structure the chaos. Discover how computers translate the real world into binary and organise massive amounts of information using arrays, trees, and relational databases.
Turn raw facts into powerful insights. Discover the journey from basic data to useful information and finally to the knowledge that drives smart decision-making.
Everything is binary. Learn how computers use simple 1s and 0s to represent absolutely everything, from your favourite songs and photos to complex numbers and text.
Stop data corruption in its tracks. Explore the clever error-checking tricks like parity bits and checksums that ensure your files stay safe and accurate during transfer.
Organise your code like a pro. Master the essential building blocks of data storage, from simple static arrays to dynamic lists and complex multi-dimensional grids.
Think outside the box. Discover Abstract Data Types like stacks, queues, and trees, defined by how they behave rather than how they are built, to solve complex logic problems.
Unlock the power of big data storage. Learn to design efficient relational databases, link tables with keys, and use SQL to ask complex questions and uncover hidden trends.
Too big for Excel? Dive into the world of Big Data and the 3 Vs. See how massive, fast-moving datasets are analysed to predict the future and power modern AI.
