Covers Finite State Machines (FSMs), Turing machines, the Halting Problem, and BNF grammar notation. Essential for AQA A Level Computer Science (7517).

Theory of Computation

Big-O notation, time and space complexity, sorting algorithms (bubble, merge, quick), searching algorithms, and Dijkstra's shortest path algorithm.

Fundamentals of Algorithms

Stacks, queues, linked lists, binary trees, graphs, and hash tables — their implementations and use cases in AQA A Level CS.

Fundamentals of Data Structures

Pure functions, lambda calculus, higher-order functions, map, filter, reduce, and the principles of the functional programming paradigm.

Functional Programming

CPU components, the Fetch-Execute cycle, instruction sets, RISC vs CISC architecture, pipelining, and cache memory.

Computer Organisation & Architecture

Relational databases, SQL queries, normalisation (1NF, 2NF, 3NF), ACID properties, client-server databases, and concurrency control.

Fundamentals of Databases

Network topologies, TCP/IP protocol stack, packet switching, encryption, firewalls, and network security threats and countermeasures.

Communication & Networking

Characteristics of big data (volume, velocity, variety), distributed processing, machine learning concepts, and data mining techniques.
