What are loop cards?

Loop cards are a great game that can be played individually or as a class. They are perfect for review key vocabulary or questions at the end of a topic or when revising for an exam.

Instructions

  1. Cut out the cards from the paper horizontally (but don't cut them in half!) and then shuffle them.
  2. Now start joining each question on the right hand side of the card to the matching answer on the next card.
  3. Carry on until all the cards loop together and you have competed the game!

Hint: Make sure that you set your paper to portrait to print 4 cards per sheet of A4 paper.

Edit Vocab

Resolution is the number of pixels per inch in an image
What is bit depth?
Bit depth is the number of bits used to represent each sample in a digital audio signal.
What is the difference between encryption and decryption?
Encryption is the process of converting plain text to coded language, while decryption is the process of converting the coded language back to plain text.
How can you tell the color of a pixel from its binary code?
The binary code for a pixel typically includes separate codes for the red, green, and blue components of its color.
What is a denary multiple?
A denary multiple is a number that is a power of 10.
How can RLE be improved for better compression?
RLE can be combined with other compression methods, such as Huffman coding, to achieve better compression.
What is the purpose of analyzing and interpreting bitmap images using binary?
Analyzing and interpreting bitmap images using binary allows you to gain a deeper understanding of how digital images are constructed and encoded.
What is the base of the denary numeral system?
The base of the denary numeral system is 10.
What is the result of adding binary numbers 1100 and 0101 without considering overflow?
The result of adding binary numbers 1100 and 0101 without considering overflow is 10001 (with no carry).
What is the strongest encryption algorithm?
Currently, the Advanced Encryption Standard (AES) is considered the strongest encryption algorithm.
What is resolution in relation to bitmap images?
