Analogue
A continuously changing wave such as natural sound.
1 of 13
Digital
Data that is made up of separate values. How data is stored on a computer.
2 of 13
Sample rate
The number of times per second that the sound wave is measured. the rate the more accurately the sound wave is represented.
3 of 13
Sample interval
The time gap between measurements of the sound wave being taken. Another way of expressing the sampling rate.
4 of 13
Sample resolution
The number of bits used to store the value of each sample. The higher the number of bits the more accurately the value is stored.
5 of 13
ADC
Analogue to Digital converter: takes real-world analogue data and converts it to a binary representation that can be stored on a computer.
6 of 13
Data
Facts and figures with no context or format to give them meaning.
7 of 13
Information
Processed data that has context and format so that it conveys meaning.
8 of 13
Instruction set
The group of instructions available for that specific processor to use. The number of instructions available will depend on the number of bits used. For example, with 4 bits there could potentially be 15 different instructions.
9 of 13
Op Code
The group of bits in an instruction that represents the operation such as EAT, MOVE or TURN (See Clarence game p18!)
10 of 13
Compiler
A piece of systems software that converts a program written in a high level programming language into machine code (binary).
11 of 13
Machine Code
A binary representation of a program.
12 of 13
High Level Programming Language
A programming language written in constructs using language we can understand. Languages include Delphi, Visual Basic, Java and C++.
