Pupils recap the denary and binary number systems from Year 7. They then learn about Binary addition and overflow errors. They will go on to tackle subtraction and binary shifts.
A series of tasks that look at the binary and denary number systems and the conversion of numbers between the two number systems.
Central Processing Unit (CPU)
The part of a computer in which operations are controlled and executed.
Random Access Memory (RAM)
RAM (pronounced ramm) is an acronym for random access memory, a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in compute
Read Only Memory (ROM)
Once data has been written onto a ROM chip, it cannot be removed and can only be read. Unlike main memory (RAM), ROM retains its contents even when the computer is turned off. ROM is referred to as being non-volatile, whereas RAM is volatile.
Storage
Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. It is a core function and fundamental component of computers. The central processing unit (CPU) of a

Word Processors
A program or machine for storing, manipulating, and formatting text entered from a keyboard and providing a printout.

A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. Their ability of computers to follow a sequence of operations, called a program, make computers very flexible and useful. Such c
Pattern Identification
Once we have decomposed a complex problem, it helps to examine the small problems for similarities or ‘patterns’. These patterns can help us to solve complex problems more efficiently.
Selection
When designing algorithms, there are many steps where decisions must be made. This decision is known as selection, and can be displayed in pseudocode or flowcharts.
Model
Computers use maths, data and computer instructions to create representations of real-world events. They also can predict what’s happening — or what could happen — in complex situations, from climate systems to the spread of rumours throughout a town. And
Abstraction
Once we have recognised patterns in our problems, we use abstraction to gather the general characteristics and to filter out of the details we do not need in order to solve our problem.
Generalisation
Generalisation is a way of quickly solving new problems based on previous problems we have solved. We can take an algorithm that solves some specific problem and adapt it so that it solves a whole class of similar problems. Then whenever we have to solve

Geometric Shapes
Many two-dimensional geometric shapes can be defined by a set of points or vertices and lines connecting the points in a closed chain, as well as the resulting interior points. Such shapes are called polygons and include triangles, squares, and pentagons.

Co-ordinates
Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ). There are several coordinate schemes commonly used by mathematicians, scientists, and eng
Iteration
When designing programs, there may be some instructions that need repeating. This is known as iteration, and is implemented in programming using FOR and WHILE statements.
Graphical Programming
In computing, a visual programming language (VPL) is any programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually.
Text Based Programming Language
Usually used in reference to a computer application, a text-based application is one whose primary input and output are based on text rather than graphics or sound.
Block Programming
In computer programming, a block or code block is a section of code which is grouped together. Blocks consist of one or more declarations and statements. A programming language that permits the creation of blocks, including blocks nested within other bloc

Nested Selection
In computing science and informatics, nesting is where information is organised in layers, or where objects contain other similar objects. It almost always refers to self-similar or recursive structures in some sense.
Iteration
Iteration is the act of repeating a process, either to generate an unbounded sequence of outcomes, or with the aim of approaching a desired goal, target or result. Each repetition of the process is also called an "iteration", and the results of one iterat
