668 free study cards across 8 topics, written to the AQA specification. Study them as flashcards or multiple choice, and rate each one Got it, Almost or Forgot.
Every card is tagged to a topic in the AQA GCSE Computer Science specification, so you can revise one topic at a time.
Three cards from the deck, as you will see them in BrainBerry: the question, the answer, and an explanation of why.
What does the operating system do when it carries out memory management?
It decides where in memory each program and its data are loaded, keeps track of the space used and free, and stops one program from overwriting another.
Processor management is the related job of deciding which program gets processor time and for how long, so several programs appear to run at once.
What is a foreign key?
A field in one table that holds the value of the primary key of another table, so that records in the two tables are linked.
Common error: a primary key identifies a record in its OWN table, while a foreign key points at the primary key of a DIFFERENT table.
What is the job of a NIC?
A network interface card is the hardware inside a device that lets it connect to a network and send and receive data.
Every NIC is given a unique MAC address when it is manufactured. A device with both wired and wireless NICs therefore has two MAC addresses.
Practise the June 2024 and 2025 AQA Computer Science papers question by question. Every question on the paper has its own set of BrainBerry flashcards and multiple-choice cards, testing the same content and skills, each with an explanation.
The cards are written by BrainBerry to match each question; they are not the exam board's own wording.
