Binary

Binary is an information system made of ones and zeros that allow computers to communicate. For Example, 00000000 is equal to 0 because none are ones. 00000001 is equal to one, because the first part is on. 00000010 is 2, because each part to the left is double the value on the right.

Binary is normaly talked about in bytes, which are 8 bits. If your download speed is 20 KBs per second, it is 160,000 on or off switches per second.

Images are sent with 3 bytes, one for the strength of the red, blue and green. Then the computer detects this and turns it into one pixel. So a 4k by 4k tv has 384,000,000 bits just for the colour.
