    ▪ You write a web address to your browser
    ▪ Computer sends a request to DNS to receive the destination IP address
    ▪ Computer sends a request data to destination IP address
    ▪ Data hops from one router to another finding the best way going over different Tier
    Networks
    ▪ Server receives the data and sends the response data
