Computer science (also called computing science) is the study of the theoretical foundations of information and computation and their implementation and application in computer systems. One well known subject classification system for computer science is the ACM Computing Classification System devised by the Association for Computing Machinery.

Computer science GCSE and A levels have been made more rigorous. From around 2014 the new Computing GCSE has been taken. In November 2018 the government-funded National Centre for Computing Education was founded at the University of York , to coordinate training for computing teachers in England.
Computer science is the study of computation, information, and automation. [1] [2] [3] Computer science spans theoretical disciplines (such as algorithms, theory of computation, and information theory) to applied disciplines (including the design and implementation of hardware and software).
2023: OCR was criticised by pupils and teachers for the level of difficulty in Paper 2 of the Computer Science GCSE. [22] [23] Students took to social media to express concern at the disparity between Paper 1 and Paper 2, as well as the change in style of the paper. OCR assured students that the final mark scheme would reflect the different ...
For example, a computer with internet access could be considered a child node of a node representing the internet. The inverse relationship is that of a parent node. If node C is a child of node A, then A is the parent node of C. Degree: the degree of a node is the number of children of the node.
Compiler software interacts with source code by converting it typically from a higher-level programming language into object code that can later be executed by the computer's central processing unit (CPU). [6] The object code created by the compiler consists of machine-readable code that the computer can process. This stage of the computing ...
NP-completeness reduction from 3-satisfiability to graph 3-coloring.The gadgets for variables and clauses are shown on the upper and lower left, respectively; on the right is an example of the entire reduction for the 3-CNF formula (x ∨ y ∨ ~z) ∧ (~x ∨ ~y ∨ z) with three variables and two clauses.
