Q: Match the titles to the correct definitions:
- The set of symbols that can be represented by a computer. | Character set
- A 7-bit character set used by PCs. | ASCII
- An 8-bit character set used by older mainframe computers | EBCDIC
- A 16-bit character set that allows many more characters to be coded including international alphabets. | Unicode
- An image that has is stored an processed as a series of values per pixel. | Bitmap image
- An image file that is made up of lines and shapes that have certain properties. | Vector graphic
- Short for picture element. It is the smallest component of a bit-mapped image. | Pixel
- The number of bits used to represent the colour of a single pixel in a bitmapped image. | Colour depth
- The number of pixels in an image | Resolution
- The data that a computer needs to correctly interpret the image data in a file. | Metadata
Also offered: Hexadecimal; A character string

Q: Match the titles and definitions:
- A continuously changing wave such as natural sound. | Analogue
- Data that is made up of separate values. How data is stored on a computer. | Digital
- The number of times per second that the sound wave is measured. The higher the rate the more accurately the sound wave is represented. | Sample rate
- The time gap between measurements of the sound wave being taken. | Sample interval
- 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. | Sample resolution
- Takes real-world data and converts it to a binary representation that can be stored on a computer. | Analogue to Digital converter
- Raw facts and figures with no context or format to give them meaning. | Data
- Processed data that has some context and format so that it conveys meaning. | Information
- The group of commands available for a specific processor to use. | Instruction set
- The group of bits that numerically represent a set of instructions | Op Code
- A piece of systems software that converts a program written in a high level programming language into machine code | Compiler
- A binary representation of a program. | Machine Code
- A programming language written using a language that humans can understand. Examples include Delphi, Visual Basic, Java, Python and C++. | High Level Programming Language
- A programming language written using a language that computers can easily interpret. Examples include Assembly and Machine Code | Low Level Programming Language
Also offered: Pseudocode

Q: Match the words and definitions together:
- A single binary digit: 1 or 0 | Bit
- 8 bits | Byte
- 4 bits | Nibble
- 1024 bytes | Kilobyte
- 1024 kilobytes | Megabyte
- 1024 megabytes | Gigabyte
- 1024 gigabytes | Terabyte
- Base 2 number system, used by computers, uses the digits 1 & 0 only | Binary
- Base 10 number system, how we normally count, uses digits 0 to 9 | Denary
- Base 16 number system used by humans to represent groups of four bits at a time. Uses digits 0 to F | Hexadecimal (hex)
- When the result of a binary calculation is too large to be stored in the space reserved for that type of data | Overflow
