Flashcards for Singapore-Cambridge GCE A-Level H2 Computing (syllabus 9569), split into the six modules of the 2027 syllabus and then by topic within each. Covers programming fundamentals, data structures and algorithms, data and information, computer networks, the social, ethical and security impact of computing, and emerging technologies including machine learning.

Adding it gives you your own copy, with every subdeck below. Each card then comes back just before you would forget it, and every one you get right or wrong counts towards your mastery of its topic. You can delete or suspend the parts you are not studying once it is yours.

Some of its cards

  • The single node at the top of a tree, with no parent node above it
    Root (of a tree)
  • What does Big-O notation describe?
    How the running time (or other resource use) of an algorithm grows as the size of its input grows
  • How does a web application differ from a native application?
    A web application runs inside a web browser and is accessed over a network; a native application is installed directly on a device and runs using that device's own operating system
  • Database
    An organised, persistent collection of data, structured so it can be stored, searched and updated efficiently
  • Keeping data accessible only to the people who are authorised to see it
    Confidentiality (information security)
  • Why does good code use consistent indentation and white space?
    It shows which lines belong to the same block, such as the body of a loop or function, which makes the structure easier to read
  • A data structure that stores items so the last one added is the first one removed (last in, first out)
    Stack (data structure)
  • What does `f = open("scores.txt", "r")` do?
    Opens the file `scores.txt` for reading, and assigns the file object to `f`
  • Under the Personal Data Protection Act (PDPA), what three things does the Act govern about personal data?
    Its collection, its use and its disclosure by organisations
  • What is Unicode?
    A character encoding standard that assigns a unique number (code point) to characters from almost every writing system, so text in any language can be represented consistently
