Data representation and Binary Numbers
This resource contains a number of activities and worksheets to support the topic of binary numbers. The content looks first at binary numbers, how they represent denary numbers, converting between the two, binary addition and using two's complement to represent negative numbers and thus perform subtraction. These are supported by a number of worksheets containing questions on each topic. The resource also looks at ways to represent fractional numbers in binary using fixed point and various ways of encoding images, resolutions and colour depths. Finally there is a section on how audio is encoded/represented, this includes a worksheet with some suitable tasks. The original presentation was delivered as part of a CPD session, and so may need some modification before using with a class.
