Computing: Theory

What is Binary? Class discussion. VideoKey words: DenaryEveryday number system 1,2,3,4,5…..Also called Base-10ASCIIComputers can only understand numbers, so an ASCII code is the numerical representation of a character such as 'a' or '@' Task 1: Create binary numbers on 1_Binary_Code worksheet.Task 2: Work through the mission with Mr Bond : 2_ Crack_The_Code worksheetTask 3: Load up 3_Binary Game Link and play the game.Extension: Load up 4_Binary Code Student.

Be able to recognise binary code

How do computers work?A Computer is ran by a CPU (Central processing unit), it’s kind of like the computer’s brain.

The CPU has lots of little switches in it that can either be ON (a 1) or OFF (a 0)

What is Binary Code?Binary code is the only thing the CPU understands.

Everything you put into a computer is converted to Binary code for the CPU to process.

Binary code is made up of 1’s and 0’s. The computer then translates these 1’s and 0’s into

everything else.

Even images your see are made up of 1’s and 0’s
