I've spent half my life sending out these letters to people all around the world here at Australia Post, but it got me thinking about how people send words and pictures over the internet nowadays?
Encoding Images, A step into the digital world.
Images on a computer are digitally displayed using pixels, these pixels all represent a colour and your screen displays that colour for each individual pixel
These pixels are broken down from the overall image and sent through the internet through a router in small groups called packets.
Imagine the internet as one big wire going across the world, certain computers called servers can connect directly to that wire but the computers we use in everyday life need something called router to correctly transport what we send from our computer to the desired location.
Now, back to images, How are they read by a computer? Binary is the language computers use to communicate with each other. It involves using a series of 0s and 1s to represent certain values.
