Why we need port, IP & MAC address in computer networks?

good description!

Well done bro !!!

Good Explanation bro!

so when MAC is gonna be change and replace in routing process, why pc assigns it?

Plz make your video's in HINDI , 🙏🙏

Excellent point to point description, Thank you so much🙏 and all the best 👍 😊

Very nice 👍🏽

well done

Is MAC routable outside LAN? As far as i know MAC is use in LAN to communicate to each other. A LAN has 5 machine connected, When a particular machine request for a data/website. That data packet entered into router by using IP only. After that it goes to switch of that LAN. The switch add the MAC address over the packet along with IP and order the data packet that, by which machine that data has been requested ! Or in other words, It helps data to id that particular machine on a LAN. If MAC is not available, then the data packet will not understand that particular machine connected in LAN and that same data can be visible by that all 5 machine in that network. Router works on IP only outside LAN to fetch a Website ! That's what i know.

Great video

I really appreciate video, I now get the concept... process to process, node to node etc. When i read that the MAC address changed as travelled across the network it really didn't make sense until now. Much thanks

Bro I can't find the subnetting videos made by you earlier. Can you upload it again?

Excellent example.

Crystal Clear 💖

The best explanation on TCP/IP Addressing

So router contain Mac address like switch ?

Very helpful, thank you

Nice work. Keep going. Thanks

wonderful explaination . I got to know about usage of ip mac and port numbers in just 5 mints because of u sir..

if a packet comes from internet then my router can just send it to my private ip address why Mac address is needed then

really an amazing video.. great explanation

simply, i'm not gonna say that u need it in the osi model or the switch have to use it ,but why did the ieee or whatever company created two addresses what was the probleme that they have faced ?the ip address has info about the network u can't use the mac address to know which network are u sending to , so routers wont know whats the next router or domain to send to get to that lan , then the question is that why people didnt just use the ip address to connect between the routers , lans etc when it covers all network / devices info , the answer is inside a local area network to reduce the processing of the intermediate device(switch ,hub...) the solution is that intermediate doesnt need to go through all the osi model it just can go through layer 2 so its faster thats where it came the mac address
