In computing, a bit is

• 8 bytes

• A single 0 or 1

• A single pixel

• 4 bytes

What is the point of binary?

• It represents how computers interpret electrical signals

• It lets you do maths tricks

• It represents how humans like to work with numbers

• It makes the electronics in computers more complex

Why do computers use binary?

• Because CPUs have 2 cores

• To represent the 2 different states of transistors (on and off)

• To allow the CPU to be in one of 2 states

• To make the CPU more complex

Binary is the language ​​ (a)   ​ use to communicate. They only use 1s and 0s.

​ ​ (b)   use 1's,10s,100s,1000s. This is called base 10. Computers use base 2 as they only​ ​ (c)   two states:  1 for ​ (d)   ​ and 0 for ​ ​ (e)
