0:00:03.940000 --> 0:00:08.760000
 Hello and welcome to this presentation
 by INE of understanding common

0:00:08.760000 --> 0:00:11.080000
 network applications.

0:00:11.080000 --> 0:00:15.900000
 I am Keith Bogart and I'll be your instructor
 for this series of videos.

0:00:15.900000 --> 0:00:19.220000
 So let's talk a little bit about the
 objectives of this series of videos.

0:00:19.220000 --> 0:00:23.180000
 What am I hoping that you as the
 learner will get out of this?

0:00:23.180000 --> 0:00:26.280000
 Well number one, I'm hoping that I can
 provide you a high level overview

0:00:26.280000 --> 0:00:30.600000
 of common application characteristics
 and mechanics.

0:00:30.600000 --> 0:00:31.920000
 What does that mean?

0:00:31.920000 --> 0:00:37.180000
 So this, if I go forward a little bit
 here, this course is really designed

0:00:37.180000 --> 0:00:42.220000
 for the entry level CCNA learner, the
 person who is just starting out

0:00:42.220000 --> 0:00:47.440000
 learning the CCENT, otherwise
 known as the ICND1 topics.

0:00:47.440000 --> 0:00:52.080000
 Someone who has little to no networking
 or computer knowledge.

0:00:52.080000 --> 0:00:57.660000
 I've known plenty of people in my day
 who use their laptops strictly for

0:00:57.660000 --> 0:01:03.300000
 browsing the internet, looking for
 news, placing orders on amazon.com,

0:01:03.300000 --> 0:01:05.260000
 reading their Gmail.

0:01:05.260000 --> 0:01:10.180000
 But other than that, when I start throwing
 terms at them like telnet,

0:01:10.180000 --> 0:01:15.140000
 HTTP, DNS, they have no idea
 what I'm talking about.

0:01:15.140000 --> 0:01:18.600000
 I've had plenty of students in my CCNA
 bootcamps who've come to me when

0:01:18.600000 --> 0:01:22.140000
 I teach that, who terms mean.

0:01:22.140000 --> 0:01:26.000000
 So this is really geared for
 that section of an audience.

0:01:26.000000 --> 0:01:30.320000
 People who want to know a little bit
 more about, okay, when I bring up

0:01:30.320000 --> 0:01:34.000000
 my browser, what's really happening
 in the background?

0:01:34.000000 --> 0:01:38.720000
 I don't need to know the gory details,
 but what makes web browsing work?

0:01:38.720000 --> 0:01:40.900000
 What makes email work?

0:01:40.900000 --> 0:01:43.060000
 What's going on underneath
 the hood?

0:01:43.060000 --> 0:01:47.080000
 And certainly when we get into the role
 of networking, a very common application

0:01:47.080000 --> 0:01:51.100000
 you're going to be using a lot in
 the world of networking is telnet.

0:01:51.100000 --> 0:01:53.460000
 And what's going on when
 you telnet to something?

0:01:53.460000 --> 0:01:55.240000
 What does that really mean?

0:01:55.240000 --> 0:01:57.280000
 What's that protocol doing?

0:01:57.280000 --> 0:01:59.860000
 And so that's why I'm going to sort
 of be covering in this series.

0:01:59.860000 --> 0:02:04.200000
 I'm also going to talk at a high level
 of some sort of general characteristics

0:02:04.200000 --> 0:02:09.600000
 of network based applications, some
 categories they fall into, certain

0:02:09.600000 --> 0:02:13.940000
 silos that sort of describe
 how they work in general.

0:02:13.940000 --> 0:02:16.600000
 And we're going to be covering
 that in a series of videos.

0:02:16.600000 --> 0:02:21.140000
 So, my agenda, I'm going to start real
 briefly with a video on what do

0:02:21.140000 --> 0:02:24.300000
 applications have
 to do with a CCNA?

0:02:24.300000 --> 0:02:27.760000
 Most people who are studying for the
 CCNA or maybe have heard about a

0:02:27.760000 --> 0:02:32.520000
 CCNA, what comes to their mind
 is routing and switching.

0:02:32.520000 --> 0:02:36.920000
 And if I'm thinking about Cisco routers
 and Cisco switches, why would

0:02:36.920000 --> 0:02:38.920000
 I have to know anything
 about applications?

0:02:38.920000 --> 0:02:42.260000
 Isn't that something that the server
 guy or the server gal is going to

0:02:42.260000 --> 0:02:44.040000
 do over there? I'm the routing
 and switching person.

0:02:44.040000 --> 0:02:47.660000
 Let the server person worry
 about the applications.

0:02:47.660000 --> 0:02:51.000000
 Well, even if you're fortunate enough
 to get hired into a company where

0:02:51.000000 --> 0:02:55.300000
 you can specialize in just the routers
 and just the switches, which is

0:02:55.300000 --> 0:02:58.660000
 rare, because most companies these days
 will also want you to do a little

0:02:58.660000 --> 0:03:03.040000
 bit of stuff on the servers also, you have
 to know something about applications.

0:03:03.040000 --> 0:03:06.960000
 You can't be completely ignorant about
 some of the most common applications

0:03:06.960000 --> 0:03:08.800000
 that are out there and
 what they're doing.

0:03:08.800000 --> 0:03:10.780000
 And so we're going to talk
 a little bit about that.

0:03:10.780000 --> 0:03:17.280000
 I'm again going to provide
 an overview of TCP and UDP.

0:03:17.280000 --> 0:03:20.340000
 And then the applications that we're
 going to dive into is the domain

0:03:20.340000 --> 0:03:22.460000
 name service DNS.

0:03:22.460000 --> 0:03:26.240000
 We'll go into some categories and types
 of applications and then we'll

0:03:26.240000 --> 0:03:30.840000
 look at email, web browsing
 and telnet.

0:03:30.840000 --> 0:03:34.220000
 So those are the video breakdowns that
 we're going to be having in this

0:03:34.220000 --> 0:03:37.440000
 particular course and what we're
 going to be talking about.

0:03:37.440000 --> 0:03:41.120000
 Now, as far as prerequisite knowledge
 is concerned, don't really have

0:03:41.120000 --> 0:03:45.820000
 to have any. This is a very fundamentals
 low level CCNA course.

0:03:45.820000 --> 0:03:51.120000
 So other than being able to open up
 a computer, turn it on and maybe get

0:03:51.120000 --> 0:03:53.660000
 into your web browser,
 that's about it.

0:03:53.660000 --> 0:03:56.860000
 So I'm not expecting that you really
 know a whole heck of a lot here for

0:03:56.860000 --> 0:04:02.020000
 this class. As far as Q&A is concerned,
 this class right now, as I'm recording

0:04:02.020000 --> 0:04:06.760000
 it, I am also delivering it to a live
 audience as well, a live internet

0:04:06.760000 --> 0:04:10.800000
 audience. And they have the ability
 to ask me questions as I go along

0:04:10.800000 --> 0:04:14.460000
 here. So in these recordings, you might
 see me responding to questions

0:04:14.460000 --> 0:04:17.140000
 that are posed to me
 from that audience.

0:04:17.140000 --> 0:04:21.780000
 However, you who is watching this as
 a recorded session, what do you do

0:04:21.780000 --> 0:04:24.320000
 if you have a question
 as I'm going along?

0:04:24.320000 --> 0:04:29.280000
 Well, certainly my number one response
 to that is I recommend that people

0:04:29.280000 --> 0:04:34.340000
 go to the INE online
 community, the IEOC.

0:04:34.340000 --> 0:04:38.020000
 And if you've never seen the IEOC before,
 let me just show you briefly

0:04:38.020000 --> 0:04:40.140000
 what that looks like.

0:04:40.140000 --> 0:04:42.240000
 So I'll pull this over here.

0:04:42.240000 --> 0:04:49.520000
 So if you go to the members dashboard,
 and if you're watching this video,

0:04:49.520000 --> 0:04:51.720000
 I assume you have
 a members account.

0:04:51.720000 --> 0:04:54.880000
 So if you go to your members dashboard
 here in the upper right corner

0:04:54.880000 --> 0:04:58.660000
 where it says connect, if you click
 on that arrow, you'll see that the

0:04:58.660000 --> 0:05:01.860000
 first link is for the IEOC.

0:05:01.860000 --> 0:05:04.260000
 That's the INE online community.

0:05:04.260000 --> 0:05:06.400000
 You can click on that.

0:05:06.400000 --> 0:05:11.080000
 And then here in the upper left where
 it says CCIE forums, click on that.

0:05:11.080000 --> 0:05:13.680000
 Now you might be saying, wait, hold
 on a second Keith, I'm not studying

0:05:13.680000 --> 0:05:15.900000
 for my CCIE. That's okay.

0:05:15.900000 --> 0:05:17.640000
 That's just the title
 of this link.

0:05:17.640000 --> 0:05:21.000000
 We have a lot of forums for
 things other than CCIE.

0:05:21.000000 --> 0:05:24.940000
 So just click on CCIE forums.

0:05:24.940000 --> 0:05:28.420000
 And then if you have any questions regarding
 stuff that I'm talking about

0:05:28.420000 --> 0:05:32.260000
 in this series of videos, I'm thinking
 it'd probably be most applicable

0:05:32.260000 --> 0:05:37.120000
 to post those and like just
 the generic CCNA forum.

0:05:37.120000 --> 0:05:41.140000
 So if you scroll down, it's about three
 quarters of the way down here

0:05:41.140000 --> 0:05:44.060000
 under CCNA and CCMP forums
 you can see here.

0:05:44.060000 --> 0:05:46.540000
 It's about the sixth
 link down CCNA.

0:05:46.540000 --> 0:05:51.400000
 And you can just click on that and
 then you can write a new post.

0:05:51.400000 --> 0:05:55.780000
 So go ahead and put a post out there
 about the question that you have.

0:05:55.780000 --> 0:05:58.800000
 And there's hundreds of people
 that look at this thing.

0:05:58.800000 --> 0:06:03.840000
 So guaranteed within less than a day,
 you will have an answer to your

0:06:03.840000 --> 0:06:08.120000
 post. That's my preferred method because
 that way the knowledge is being

0:06:08.120000 --> 0:06:11.440000
 shared. Other people get
 to see your question.

0:06:11.440000 --> 0:06:14.720000
 Other people get to learn from
 the answer in addition to you.

0:06:14.720000 --> 0:06:19.860000
 Now on the rare chance that you post
 a question here and you get no answer

0:06:19.860000 --> 0:06:22.420000
 whatsoever, does not
 happen very often.

0:06:22.420000 --> 0:06:23.260000
 But let's say that happens.

0:06:23.260000 --> 0:06:28.200000
 Let's say you post it there and you
 wait like two days and you haven't

0:06:28.200000 --> 0:06:29.440000
 heard anything back.

0:06:29.440000 --> 0:06:33.800000
 Then in that case you can see right here
 I've provided my INE email address.

0:06:33.800000 --> 0:06:37.960000
 So feel free to reach out
 to me directly via that.

0:06:37.960000 --> 0:06:41.880000
 I've also provided how you can connect
 with me on Twitter so you can post

0:06:41.880000 --> 0:06:46.260000
 questions there or you can follow what
 classes I'm coming up with in any

0:06:46.260000 --> 0:06:47.940000
 news I put on there.

0:06:47.940000 --> 0:06:51.280000
 And also if you're a follower of LinkedIn,
 you can connect with me on

0:06:51.280000 --> 0:06:54.640000
 LinkedIn as well and send me
 messages and questions there.

0:06:54.640000 --> 0:06:58.580000
 So there's a variety of methods that you
 can use to get answers to whatever

0:06:58.580000 --> 0:07:00.020000
 questions that you have.

0:07:00.020000 --> 0:07:04.740000
 So with that, I'm going to go ahead
 and close off this video and let's

0:07:04.740000 --> 0:07:10.100000
 start the next video on what do applications
 have to do with a CCNA?
