Comprehensively elaborated. Thank you so much for this video tutorial. Can you please make a video about Jitter, Latancy and Round Trip Delay as well. That would be very helpful for several networking associates.
Somehow these videos teach exactly what I need to know and leaves out what I don't need to know. Fantastic visuals. Maybe its the simplicity of the videos, but they sure help me to learn especially for someone not in IT. These videos are instant classics
its amazon mate, did you watch DCEU wonderwoman already? U can see how many woman there, did u ever wondered why they have children in the amazon island? why they didnt extinct? Legend says (the movie didnt mentioned it, but it actually fkin canon). This man wich we witness this enlightnment about fkin "PING", that every woman in the island is his harem and the child is his daughter. And may u furtherly wondered why the women in the island is look so stronk, an the answer is he distributed his strength evenly to all amazonian so he can concentrate to enlighten us and freed from ignorance.
Ping and tracert use ICMP (Internet Control Message Protocol). This protocol is primarily for network error reporting. Ping uses port 7. So it means if port 7 is blocked anywhere on the way, the ping will fail with destination not reachable. So ping does not always help to check if the remote device is up. Even if a ping fails, other applications using ports other than port 7 may still work. Ping is a very basic check utility.
It should be noted that the "tracert" command is Windows-OS specific. Mac OS X and Linux distros use "traceroute" Same functionality is provided though!
This is the new Google search address for IT beginners, great explanation and precise content. Hope we get a face cam video of you explaining with the animations rolling. Wait a minute.... That would be awesome!!!
Just to add ,a tracert is a ping command with increasing TTL(time to live) starting from 0 hops till it reaches the destination , A TTL=64 means a packet should go less then 64 hops to get a reply or we will get TTL exceeded message .
Also for those who don't know, TTL in your ICMP echo replies stand for time to live. Each time an echo request or any data packet traverses through routers on its way to the destination, the TTL flag in the encapsulated packet header decreases by one. The reason for this flag is that if a router or routers have improper routing table configurations, the packet can get stuck in a loop, bouncing back and forth endlessly thereby consuming bandwidth on the links and hardware resources such as memory and processing on the affected routers, ultimately never reaching its intended target. To mitigate this problem, the TTL decreases by 1 every time the packet passes through a router and if the packet hasn't reached its intended target when the TTL reaches zero, the packet is dropped from the last router. Typically though, network engineers will configure what's called a "black hole route" on routers in that if the packet doesn't match any of the specified routes in the routing table, it is then immediately sent to the black hole route where it's immediately discarded instead of waiting and relying for the TTL to expire.
Linux continues sending packets, not just four, which is kind of handy when troubleshooting wiring problems. There are ways to disable ping from replying on a system. There are versions of traceroute that gives you a map showing location of routers in between.

I really love all of your videos, the simplicity, direct to the point and creative visual makes computer learning easier and fun. Thank you and keep up the great work.
Wow I understand your videos better than the videos we get for College. Not saying the vids in college aren't any good because they're good but the way you present your lessons through animation really helps! Keep them coming, I subscribed.
It's "traceroute" in the Linux shell and there's also the "mtr" command which is like ping and tracert combined with lots more (install the mtr-tiny package)
Such a great way to explain technical concepts...!!! Your animation is too good that it even clear the concept better than book. Thank you for creating such perfect multimedia content. We hope to see more from your end....!!! Best of luck.
nice you keep it simple , I am amazed i talk to AT&T techs and many have no clue about trace routing , it's so basic, and i keep telling AT&T that they need to upgrade and update their internal networks, that have been using the same equipment for over the last decade. it's usually were their slowdowns are, before the packet connects to the internet backbone.
Your vids are AWESOME!!!👊🏽👊🏽 I just bought your e-book “Comptia A+”. All this info will help me perform better as a student when I enroll in the Computer Repair / Networking Certification course at tech school. Keep up the good work!!!
I am really a big fan of all your videos. It's been a while since a watch them for the last time, gonna watch them all again so I can relearn what I forgot.
Wanted to give you a shout out that the ads are worth watching fully to support your channel because you make amazing videos. Keep it up and thank you!!
@@erentriptide7535 i work on smart meters for the electrical grid which will transform the world. I can confirm these are essentials commands that i use all the time
TRACERT NOT EXPLAINED WELL, Tracert sends each packet with incremental TTL value starting from 1 So the first packet expires at first node (most probably your home router) and the node sends back an echo packet this way we get to know the IP address of the node, Then it sends the next packet with TTL 2 and so on until we reach the final destination.
