Why do packets split data?
Each packet has a limited size.
What data does a packet contain?
The sender’s IP address, the destination IP address, the data being sent and the order it has to be rebuilt in.
How are packets sent through the Internet?
Your LAN connects to the Internet (a WAN) and sends the data to the receiver’s LAN.
How do LAN’s stop packets affecting network performance?
They use a proxy to find the URL of the data.
How do firewalls stop packets from sending restricted data?
They open the packet and scan it, and quarantine the packet if it contains anything malicious.
