Sir I am going to school to become a Network engineer and I have watched a lot of your content, you inspire me. I am 40 years old and I always loved hardware and what the guys in the closet did. I made a decision to do something I have a passion about. I was in finance for years and hated it. I study 3-4 hours a day and a lot of the time 6 hrs because I love the science behind every part of this sport. Thank you for doing these videos and being honest about the industry. You are my favorite resource online. Continued success !!!!!

I see you made this comment 1 year ago , How are things going for you? I find myself in the same boat as you , I'm 36 and trying to make a career in IT technology . There are lot of "elements" that strive to blow us astray. There are challenges, In case you have had to face these hurdles then I would say "jump" Jump ... now let the van halen tune sink in for a bit. Now, arise and stay the course. In case you are doing great and did not need the motivation I say still great. Your comment actually has inspired me to carry on .. carry on .. now let Queen sink in for the bit .

[@raserapps8230]

I saw the comments and wanted to speak up too :) I am 33 and just started my studies in Computing and IT but it is mainly programming and development, I have no qualifications, and a lot of difficulties that have held me back in areas I've been programming with Python for about 3 to 4 years now but all self taught, from buying a £30 raspberry pi and searching for tutorials, but with no structure. The internet is an amazing tool for self-learning but it is just mayhem if you aren't structured with what you want to do. So I managed to get funding for my studies and I am now doing a degree in University of Wales UK - the degree is Computing and IT, but this first term I am learning 2 modules Maths (compulsary for programming in this Uni) and Technologies in Practice which has been awesome so far...Block 1 we covered robotics and programmed simulated bots and lego mindstorms to do all sorts of cool stuff like robot grand prix's and search and rescue simulations with programming :) I won the Grand prix by hacking into the coding interfaces encrypted config files and editing the power to the robots wheel motors. Everyone, including me, set their power to max (10) at the start line, and mine shot into the lead - I almost lapped them - and the looks on their faces when mine sped off and left them behind was priceless! We are now covering Networking, mainly for Windows systems and it is a little hefty to read in comparison but the next block is Linux - Next term we are going into Java and also web development languages. I am loving it - and Eli has been a great source of information for me. Even if I don't get a career in the industry I will find a way to program or develop from home. I am looking into Penetration testing and web security, but also AI - like Automated Cars etc

Between servers, computers, VOIP landlines, mobile phones, tablets, and printers we are running out of IP addresses on the single subnet in our small, but growing company.

In order to get rid of IPv4 networking, all analog or 56k wired usage would have to be replaced to a digitized medium. Not gonna happen. 5G networking, however, can be a valid option to fiber speeds within a network. Look, we dont even have all dial up lines upgraded to DSL, nor does 4G LTE work everywhere, just as 5G will take about 5 years before we see anything in rural areas such as mine.

Have you ever thought about updating these videos

[@FIXProtocol]

Internet was not created for war. That was a rumor. "The ARPANET was not started to create a Command and Control System that would survive a nuclear attack, as many now claim. To build such a system was, clearly, a major military need, but it was not ARPA's mission to do this; in fact, we would have been severely criticized had we tried. Rather, the ARPANET came out of our frustration that there were only a limited number of large, powerful research computers in the country, and that many research investigators, who should have access to them, were geographically separated from them"

[@Jennifrer83]

The TCP/IP protocol was a U.S. department of defence project to create a method for government computers to talk to each other regardless of their manufacture the OSI model was developed by the International organization for Standardization. when the two models went public many thought OSI would win the popularity contest; however in the same fashion that VHS beat Beta max TCP/IP beat OSI, OSI is still used in discussion as it does do a better job of dividing and defining the functions of network communication. but the actual protocols we use in todays internet are TCP/IP which was a D.O.D. project. the actual communication lines that we use were developed by private companies trying to get phone and tv signals into homes. If we look at who made the physical network the internet was created by AT&T and other companies like it.

[@geoffreyengatkinson]

he didnt say the internet he said the TCP/Ip

[@FIXProtocol]

Geoffrey Eng Atkinson OK...TCP/IP was not created for war.

[@geoffreyengatkinson]

it was created from security guys!

[@ingenfare]

Packet switching was created by university's with support of darpa. Google or youtube Leonard Kleinrock to learn about the start of Arpanet. The point was as FIXprotocol said was to connect large research computers. I can not see that the TCP protocol is espesially designed for war networking but for handling ordinary traffic situations.

[@frikvanwyk6559]

I am an electronic / electrical technician and these days dealing allot with networking. Thanks allot, the way you explained everything makes allot more sense to me. I l know that it is important to have the same subnet but did not know exactly know why.

[@Onlyme2015]

Great video. I'm confused about two things: First, I thought the ISP the ones that assigns IP addresses to device, not the DHCP? Second, I thought each time a device connects to the internet, it gets assigned a different IP address. Thats why the ISP needs to know the log in time of the device in order to know who uses it, This goes against the concept of lease time which claims IP addresses stay assigned to a device for a number of days.

[@MrStraightahead]

+Onlyme2015 , Eli repeats his scenarios (over and over and over again) using 'lame' if not poorly conceived metaphors', misinformation, or labors over details that aren't necessarily important when it comes to teaching concepts. Any new student to TCP/IP will either get totally confused and or simply fall asleep.

[@elithecomputerguy]

+Erv Howe "lame"..? feel free to to provide a link to your high quality content. Creating training for a mass audience is not as straight forward as it may seem. I'm completely fine if you don't like my work, but insulting free training that is provided for free is a bit tedious...

[@MrStraightahead]

+Eli the Computer Guy, sorry Eli. I didn't mean to offend your teaching skills which are generally very good. Especially for noobs. I was only pointing out that sometimes the metaphors and whiteboard drawings can easily be misinterpreted and a bit too oversimplified in areas that should in and of itself quite complex. Not the least of which is subnetting. As an instructor myself, I get the most 'ah-ha' moments by using typical CCNA test questions and parsing them to a more granular level. Repetition of example scenarios makes things 'click' more quickly. The whole idea is to get their heads around deciphering the wording to describe a subnet vs hosts and how to break it all down to BCD/binary exercises until it clicks.

+Erv Howe Well Erv, to each his own. I love Eli's teaching and am very grateful for it. Go work on your own instructional videos if you think you can do better? I'll watch those as well.

[@geoprotube]

+Eli the Computer Guy, Eli you got my full respect. You're doing a great job with your FREE tutorials. I'm seeking for a job at the moment and your tutorials are helping me tremendously to refresh my memory and also to understand concepts that I only heard of them. Keep up your good work! Thank you.

It's some audio glitch.

[@JonathanDomah]

Audio not in stereo.

[@carzacc6394]

Eli explained it another time, it is a problem that only happened when he uploaded to KZbin, while he was focusing mainly on his own site

[@Recken1]

I'm breathing a sigh of relief at how easy you make this to understand.

[@wall37]

Ip protocol? internet protocol protocol? tcp protocol? transmition control protocol protocol?

[@wall37]

a packet or a frame? cuz I've heard that in transport=segement network=packet data link=frame physical=bits 01010101

[@wall37]

yep the osi model... why would I need to write 7layers?

[@BDBD16]

UrAvgLinuxUser OSI model has 7 layers. thats why

[@wall37]

BDBD16 -_- no shit sherlook

[@wall37]

[@juliekendrickdelaney757]

Okay, I have been dealing with enterprise networks since the 1990s and I hqve never been asked. However throughout all the experience, classes, and tutorials this process has been extremely confusing. But YOU sir, are a saint. You were able to do as Einstein stated, if you cannot explain it to a six yr old, you don't know it well yourself. Simply Awesome!!!!!

[@mapplemobs]

[@cloudybrains]

Mapple Unplug your headphones slightly, but not all the way. I have no idea why this works.
