Connected but nothing loads

My PC says it’s connected, but nothing loads.

What does the address tell you?

    How it sticks

    Read a little, answer a lot, and keep seeing what you missed until it’s yours. Then do it for real.

    Read it.

    Every lesson opens with a short study guide. It starts on a real ticket, takes about four minutes and checks you halfway through.

    Study guide 2.1 · Ports and protocols4 min

    A dental office just got a new firewall: “Since the install, the front desk can’t pull email and our support guy can’t remote into the server. What do I tell the installer?”

    TCP or UDP: how the data travels

    Before the port number comes the transport. TCP opens with a three-way handshake, numbers every segment and resends anything that isn’t acknowledged. UDP just sends.

    Quick check: a service needs low overhead and can live with an occasional lost packet. TCP or UDP?

    UDP. It skips the handshake and acknowledgments.

    Answer it.

    Ten questions a lesson, most of them tickets in the user’s own words. Every wrong option tells you why it’s wrong.

    Huge phone bill after my trip

    Which change prevents it next time?

    1. 2Set backups and sync to Wi-Fi onlyAnswer
    2. 4Switch the phone from 5G to 4GYour pick

    Escalated

    Why not “Switch the phone from 5G to 4G”? A backup uploads the same 14.2 GB on 4G, just more slowly. The data cap counts gigabytes, not which network carried them.

    Miss it, and it comes back.

    A question you miss goes on your Callbacks list. Get it right and it comes back in 1 day, then 3, then 7. Four right in a row and it’s off the list.

    Maria’s PC says “No internet” and she has a vendor call at 8:30. Walk to her desk, check the cable, run the commands and prove it’s fixed, against the clock.
