What is a Switch? A Router? What network is this? And what are these? // FREE CCNA 200-301 course

[@DavidBombalTech]

What are these networks? And what are these devices? Switch vs router vs firewall vs IPS and many more. The time has arrived for me to publish a free updated CCNA course on KZbin. This is a brand new CCNA course where I focus on using real hardware and practical demonstrations.

[@lxn7404]

The quality of this course is incredible 👍

[@rigelmandarakuriom]

Akin to a capacitor that disallows direct current (DC) to pass through from one electrical network to another is router and traffic (IP packets) from one domain to another… 😊 very interesting concept explained better here by David. Thanks 🙏 a lot!!

[@chitlitlah]

I've always thought of the switch and router like a post office. If you send a letter to someone in the same zip code (subnet), the post office just has to drop it in that person's box or send it in a truck to their house. If you send it to someone in a different zip code, the post office has to send it to the other post office or to a distribution center and let them handle the rest.

[@irtazaanwar2144]

i hope so you will conttinue making these beginner level videos plz continue. those experienced guys can wait...

[@stephanieswiga9007]

Am a total newbie and my goodness was this excellent. Great product David!

[@synthwave7]

Strange - I saw you on TikTok, watched about 15 clips. I then opened KZbin on my Windows PC and your channel appeared at the top.

[@macruz8503]

Your phone is tracking g what you watch and like….scary times actually.

[@rhiuzak_CY]

I'm not sure how to say how Grateful I'm to you for bringing this awesome CCNA course. It's gonna help me CyberSecurity. Thank you so much and I'm looking forward to watching other contents soon

[@LovelyJordy]

I’m studying for my Network + cert. thank you for this ❤.

[@DavidBombalTech]

You're welcome!

[@celebritytv3831]

This is a crazy damm good explanation for network topologies

[@kresimirpecar4925]

Only 60k subscribers... It's a shame to see that high quality channels like this one have so little subscribers... Keep up the good work, great explanations and i think easy to understand for someone with no knowledge of networking at all.

[@Jakev62]

his main channel has a few million, I don't think he advertises this channel, I found it by accident.

[@scottspa74]

Absolutely cant wait for the wireless videos. Im one of those that struggles a bit with the intricacies of wifi, especially the layer 2 implications. 👍

[@arnaudfrancktaptuekuate5367]

Advertising a CCNA course with ""What is a Switch? A Router?"" Hopefully the CCNA will prepare me for the CompTIA IT Fundamentals exam.

[@gabor_kov]

It's really good visualation, thank you

[@SalmanKhan-ks2fm]

Thank you for your effort.

[@Iamdatlegend]

Been doing networking since 2015 and this is actually my first time seeing actual 10base5,2 cables. Seein it physically now makes me wonder howmuch such topologies influenced office setups, how they're always all clustered up, side to side like on the movies you know.

[@chitlitlah]

I went to college for IT around the turn of the millennium and my college still had at least one computer lab that used thinnet (10base2). The bus cables would run a brief distance from computer to computer along the front row, and then there was a long cable that ran back to the wall and back to the first computer on the second row, and so on. Classrooms and labs are already set up in a way that makes it easy, but I imagine like you said they'd have to put more thought into it for an office and perhaps rearrange the office to make it easier.

[@DavidBombalTech]

Glad you saw something new 😀

Can you make a video on how to make our own AI IT notes holding agent?

[@israaimnati9046]

where to find a full course of this current ccna ?

[@biswajitmishra7029]

Sir where is the next episode ;) have been waiting for long

[@sunefred]

Would you mind recommending a stack of devices, like the one on your desk, I could buy to work on my Cisco skills?

[@kresimirpecar4925]

You can use GNS3 to simulate network if you want. It's free and great for learning.

[@aswinrk6155]

IPS intrusion prevention system isn't it ?

[@Cyberwolf-kp4yy]

Hey guys I have a question. Whenever a switch doesn't know an address it floods the network like a hub to find the address. After it learns the address it records it in it's Mac address table but it's gone in like a few minutes. So for instance, a few days go by and the switch needs to send a message to that same address again does it have to flood the network again like a hub to find it so it can populate it's Mac address table all over again?

[@biswajitmishra7029]

The mac address table is not gone in few minutes brother. Here are a few scenarios where a switch might forget its MAC address table: - Power Cycle: When the switch is powered off and then back on, it typically clears its MAC address table. - Aging Timeout: Entries in the MAC address table have an aging time. If a MAC address isn't seen for a specific period, it will be removed from the table. - Manual Clearing: Network administrators can manually clear the MAC address table for troubleshooting or reconfiguration purposes. - Software Reset: A software reset of the switch can also clear the MAC address table.

[@Cyberwolf-kp4yy]

@@biswajitmishra7029 oh okay thank you. So what does it mean when a Mac address is stored in the Mac table for 300 seconds and then it's gone?

[@tahersadeghi6773]

Megabet or megabit?

Your tutorials are awesome no doubt. But nobody would want to follow unordered videos. Please put a proper label and upload your videos in order in this CCNA course playlist. If it is a course then it should be in order.
