Ports and Protocols
Hey there, what's going on? Welcome to Pluralsight. My name is Tim Warner, and the name of this module is Ports and Protocols. Here at Pluralsight we have you covered for every single exam objective in the CompTIA A+ 220-901 blueprint. A learning path is a related set of courses. Each course tends to be a few hours long, it depends on the instructor, and the course is broken down at the atomic level to modules and clips. But I think I've just given you too much information. For now I just want you to know that our A+ learning path consists of an introduction course, a hardware course, networking, which is what we're doing now of course, mobile devices, and troubleshooting. And I would encourage you to cross reference all of our topics here in those four content courses with CompTIA's published blueprint that you can download for fun and for free from the comptia. org website. I've divided the material in the Networking course into eight separate modules, the first of which covered network cables and connectors, essentially OSI layer one stuff. TCP/IP basics is what we just come out of. If you've studied that module, then you know some things about the OSI reference model, and we're going to build up on that knowledge in this module. Here we're concerned with ports and protocols, following up with Wi-Fi networking, small office/home office networking, internet connection type, network architecture devices, and networking tools. I have two main learning goals for you in this module. Our first goal is understanding the common ports and protocols. Fundamentally, what is a port, what is a protocol, and how do these terms relate to the TCP/IP protocol suite? CompTIA does have a good sized handful of ports, protocols, and services that you need to know. You have to have them in your brain by the time you sit to take the 901 exam, so I certainly have you covered there as well. Let's get started.

Wi-Fi Networking
Hello there, and welcome to Pluralsight. My name is Tim Warner, and the name of this module is Wi-Fi Networking. In our Pluralsight learning path for the CompTIA A+ 220-901 certification exam we have a total of five courses. The first is an introduction to the series. Then we devote each of the subsequent four to the matching content domains in CompTIA's A+ blueprint. Check the course notes for a link to the A+ website. Hardware was our first content domain. We're in the middle of the networking one right now. Then we have mobile devices and troubleshooting. Within this eight module networking course, we begin with network cables and connectors, spend time on TCP/IP, both basics, sort of a global overview, and then a deep dive into specific ports and protocols, we're doing wireless networking presently, after which we'll get into small office/home office networking, internet connection types, network architecture devices, and networking tools. What are we going to talk about and learn in this module? First I want to make sure that you're comfortable with radio frequency, or RF, communications because that is in fact the technology that undergirds Wi-Fi. The main focus of this module is making sure you know the basic, IEEE 802. 11 Wi-Fi standards. You'll very likely see questions on your 220-901 exam that ask you to differentiate, for instance, among b, g, n, and ac Wi-Fi. And if you don't know the answers, well that's going to reduce your chances of passing the exam and earning your credential. The third subject deals with securing Wi-Fi. In particular, again, CompTIA wants us to know the major encryption protocols that are supported by the standard. Let's begin.

SOHO Networking
Hello, and welcome to Pluralsight. My name is Tim Warner, and the name of this module is SOHO Networking. For the CompTIA A+ 220-901 certification, we at Pluralsight have you covered on a per objective basis in a series of course that we call a learning path. Specifically, we have an introductory course, and then each subsequent course, hardware, networking, which is where we're at right now, mobile devices, and troubleshooting all correspond to CompTIA's published exam objectives. Please check the course notes for this module, and I'll point you to the appropriate page at the CompTIA website. In the networking table of contents, let's take a look at where we are in that scheme of things. We began this course with network cables and connectors, and then TCP/IP basics and ports and protocols. Wi-Fi networking is the module that we just came out of if you're following the course sequentially. Right now we're extending upon that discussion, this time constraining ourselves to small office/home office networking, after which we'll do internet connection types, networking architecture devices, and networking tools. We have two objectives here in this module. First of all, what is a SOHO router, and what are the features that differentiate it from other types of routers in business? Second, CompTIA has a laundry list of common configuration options that are definitely things that are important as a working A+ certified repair technician because let's face it, who doesn't have a Wi-Fi and/or a wired router to the internet, and which client does not have questions about that setup? This is some valuable information. Let's get started.

Internet Connection Types
Hello, and welcome to Pluralsight. Tim Warner here welcoming you to the module entitled Internet Connection Types. Let's take a quick look at our Pluralsight learning path for the CompTIA A+ 220-901 certification exam. If you've been following me through this learning path, you're probably a little tired of seeing this. I wouldn't blame you if you decided to skip it, to be honest. First course is very brief and serves as a global introduction. Then we have courses that map to each of the content domains in the 220-901 blueprint. There's hardware, networking, which is where we're at right now, mobile devices, and troubleshooting. In this networking course, the table of contents began with network cables and connectors, went into TCP/IP and port and protocols, then Wi-Fi networking, then small office/home office networking. Now we're doing internet connection types. Then we'll finish with network architecture devices and networking tools. What are we going to learn in this module? Well, it's pretty straight forward actually. I want you to walk away from this module knowing the basic network types. In other words, terms like local area network, metropolitan area network, and wide area network, LAN, MAN, or WAN. Once we do that, we'll do a little bit of history, talk about analog modems and dial-up internet, but I want to survey the internet connection methods that are used nowadays for residential and business class connections. In the demonstration, which I think will be a lot of fun, we're going to put these items of theory into practical application. Let's get started.

Network Architecture Devices
Hi there and welcome to Pluralsight. This is Tim Warner, as usual, welcoming you to the module entitled Network Architecture Devices. Let's buzz through our Pluralsight learning path for the CompTIA A+ 220-901 certification exam. Learning path, as you know, is a series of courses which cover every single objective for a given IT certification test. Our first course in this learning path is called introduction. Then we have a course devoted to hardware, that makes sense when we consider that the A+ is a PC repair credential. Networking, that's where we are right now. Then we have mobile devices and troubleshooting. In our networking course I've divided it into eight modules, again you can cross check these against the A+ objectives published by CompTIA, visit comptia. org for details. The first module dealt with cables and connectors. Then we did two modules on TCP/IP, one on basics, the other on ports and protocols. We spent time with wireless networking of course, then small office/home office networking, internet connection types, today we're concerned with network architecture devices, and the final module is called networking tools. What are we going to learn in this module? Well I want to understand the difference between the basic network infrastructure devices. So we're going to start at the beginning with the hub and then move our way through the bridge, the switch, the router, and so forth. We've referenced these devices quite a bit throughout this course, I think that this is going to be an edifying module for you because now we can actually deeply understand each of these devices in the context of the TCP/IP protocol suite and the OSI reference model. So related network device concepts sounds like a potpourri if you've ever watched the game show Jeopardy, and that's kind of what it is. We'll discuss things like power over Ethernet and power over Ethernet injectors. There's some good stuff in this module, I'm glad to teach it to you. Let's get started.

Networking Tools
Hello there, welcome to Pluralsight. My name is Tim Warner and this module is entitled Networking Tools. Here at Pluralsight we build learning paths to help you conquer IT certification exams. The learning path for our CompTIA A+ 220-901 certification exam consists of a handful of courses, each course in turn is composed of a series of related modules. The introduction is just what the word says, it serves to describe the certification and related topics. Hardware, again, pretty self-explanatory. If you've been moving through this learning path sequentially you're yawning, please feel free to skip ahead. We're finishing the networking course right now, this is the final module in that course. Then we have a separate course on mobile devices and then finally troubleshooting. I've divided the content for the networking portion of the CompTIA A+ 220-901 into 8 modules, and as I said this is the last one. So if you've been through them all congratulations because you've built up a really nice skill set. Network cables and connectors, and TCP/IP basics, ports and protocols, Wi-Fi networking, small office/home office networking, internet connection types, network architecture devices, and here we are, drumroll please, networking tools. What are your learning goals for this module? Pretty simple, just two bullet points, hardware tools and software tools. This is all about expanding your tools as an A+ certified PC repair technician. Now elsewhere in the learning path I teach you the tools that you should put for PC repair into your tool bag. Here we're concerned with network visualization tools, some really good practical advice here, as well as giving you what you need to know to pass related questions on the exam.
