    I'm on my 3rd modem , from Huawei . Each in the last 2 years so far has broken down – all modems , have been faulty – that's tech stuff and me – can't even run a car without it breaking down in or out of warranty , 🤭🤔😵‍💫

    I think it confuses people when they get a modem/router from the cable company.
    If you like, you can do a DIY router using an old computer/laptop. Routers are often under powered ASECs.
    Also, that router with multiple ports is a router with a switch on it. Companies will often have smart switches.
    You want a router even if you have just one device…

    it blows my mind that people have access to the internet, and still come to youtube for easy gains (too bad they're not really gains) stay stupid friends!

    Very beautifully explained. Thank you. I wish university teachers explain any subject like that.

    If I have modem that abs built in internet can’t I use a router to extend the wifi?

  8. What if I do all my business on my laptop and not a desktop? Do I still need a modem? Or can I just get a router

    So wireless modem would need a router to have a better connection for say, gaming and streaming?

    Who's actually responsible for managing peer connections? The modem or the router (if modem bridged)?

    When using a cable modem, isn't another option to use a coaxial cable splitter, and then run multiple coaxial wires to multiple modems which can then connect to multiple computers without using a router?

    Finally, I understand what modems and routers do! Thank you so much.

    Great Presentation. So we can tap directly into the Internet using a modem? What then is the goal/function of an ISP?

  15. Fernando Jackson

    Great presentation again.I'm not sure if I misunderstood you, but in another video you seem to have said that routers are used to connect between networks, as they can read IP addresses, while switches connect within networks, as they can /do read MAC addresses, so they relay messages to individual devices.

    If I were to connect my computer directly to the modem, how would that work? I was taught that in order to access the Internet I HAVE TO have a router.
