Packets

When large amounts of information (email, video, file, webpage etc.) are to be sent over the network it will be broken down into packets which contain instructions about how it fits together, where it came fro and where it’s going.


  • IP Address
    • IP address is a set of numbers that represents a unique location on the web. If you want to send a message (Packets) to another computer you need to know the IP address to send it too. But humans have a hard time remembering these numbers so we can alias it with a domain name. IP addresses can change over time (hardware updates etc). So a static domain name is the easiest way to find another computer (server) on the network^[Websites can also be reached directly via typing the IP address into your browser if you so wish.].
