Representations...

• A pattern of symbols

• A pattern of letters

• A pattern of numbers

• A pattern of pictures

Let's play a fun game of symbol detective! Can you guess what symbols are?

• Are they a type of musical instrument that you can play?

• Do they represent an image or a picture?

• Are they used in arithmetic to add and subtract numbers?

• Or are they a letter, character, or sign used instead of words?

Let's talk about storage! Can you guess what it is?

• Is it the computer's hard drives and circuitry?

• Or is it a space or place where we can store data?

• Could it be a cupboard under the stairs?

• Or is it a coding scheme?

Let's dive into the world of computers! Can you tell me what 'Communication' in computers means?

• Is it about transmitting and exchanging information, like sending and receiving messages?

• Or, is it about humans speaking to one another?

• Could it be messaging including email and SMS?

• Or, is it a sequence of symbols used to understand a message?

Let's have some fun! Can you guess what 'Processing' in computer terms means?

• Is it about reading and understanding a computer program?

• Or, is it about feeding data into a computer, so that the computer can produce a desired result?

• Maybe it's when a computer does arithmetic calculations?

• Or, could it be a special chip inside of a computer?
