If i had met this person while growing up. I can't imagine what i would be on this planet in ICT. A god i swear...... Even when I'm not doing anything related to ict I can't scroll over your video.
Well done David you have an awesome gift, the way you can explain such things in a way that its so informative but yet it's wrapped in such a simplistic package. I just stumbled on the channel, so ive only barely sampled the content, needless to say but i got me some binging to do. So far from what I have sampled 👍👍, I'm definitely recommending this channel to most of my contacts, thanks for the time you take to provide such well thought out and put together information.
Big more complicated though. Layer 3 switches exist which can work with IP addresses. Also, residential "routers" are actually a combination of a router, switch, wifi access point and sometimes a modem as well.
layer 3 switch is anouther name for some of ISP routers. Why on Earth those are named "L3 switch" is beyond me. USB-IF shows people may make some very questionable naming schemes.
Thank you so much. I am studying computer science and coding languages I understand just fine but the hardware components scare me because i have absolutely no practical knowledge 😭
Just a suggestion, why don’t you start teaching for the security courses that are offered by the ISACA Board, I am currently preparing for my CISA Certification(Certified Information Systems Auditor) and I can’t thank you enough for simplifying such tech related topics. Love from India❤
Not necesserily the switched machines will share the single ip address of a router, they dont need to have a public address or they can have different or even share many. Simply the switch interchanges the link structures of information (called frames) and works on the second level of abstraction and routers are capable of interchanging 3rd level of abstraction called packets and protocols such as IP/IPv6/old IPX/ATM/some other globally interchangeable packeting protocol :). In simple way many users are using routers for a single IP address SNAT though but lets not take them opportunity to create something special :). dont use just routers - use linux :)
@@davidbombal I did the Google IT Support course on Coursera 2 months after I was done I got a job at a data center as a data Technician, I'm really enjoying working in tech now I'm planning on moving forward, I'm currently studying for cybersecurity and your videos have really been very very very helpful. I'm loving it day by day. I also use your video as references when I don't understand some things. Please do you have a video on full Wireshark demo?
Now do one on the difference between a Modem (modulator/demodulator) and a router :3 It's the router idea, but instead of different networks, it's different mediums!
Switches have also ip routing but it routes only on the same network dhcp server, mac adreses are barely used outside of companies where you implement hardware id wich is the mac, usually old hubs had a mac routing system 😅
And I’m picking this up along the way but I’m assuming that the “Mac” in MAC address stands for macro meaning more traffic. I’ve been told that Ap’s essentially hand out IP addresses but I’m struggling to clearly understand. Does the switch “decrypt” (for lack of a better term) packets that come in from an ap and just send a packet back to the ap to determine which device needed the information?
Hi there. I have starlink and I got the ethernet adaptor as you showed in this video. I have a TP link 5 port Gigabit desktop switch. Do I still need a router to use this?
So when computer request a data package to be sent to another PC in the same network, it would include both the MAC address and the IP address of the target in the request? How does the PC know the MAC address of other PC in the network?
I connected my starlink router to my Cisco Linksys e2500 via an Ethernet cable. But my Cisco Linksys does not browse, I just don't know why it has refused to browse
