Subtitles of the Movie (CompTIA Network+ Certification (2005 Objectives) / Basic Networking / Network Requirements)
In basic networking take a look at some of the high level topics that will be covering more in detail as we pass on through our course. We talk about some of the required things, some of the things that happen behind the scenes, just can get a good idea of what networks are all about .We talk about network requirements. And these are the very simple physical requirements that we have to have in order to establish a network. Once you put those networks together they will have different types of computers and types of clients in them and depending on what those are they fall into a certain network model category. We will discus each one of those and what they are used for. Now regardless of what's contained inside a network we will fond to a physical topology which is how a network physically looks and how the computers and the components of the network have been arranged. Now you got a more connected, together and arranged the way they operate may not necessarily fall in line with the way they look. So the way they actually operate is called a logical topology. So we will discus some of the logical topologies and then we are going to mix the physical and logical topologies together and see how they act. Now network category is a geographical representation of a network. Now depending on how far your network expands, how many miles or how many buildings or lands they expand they will find different network categories. So let us start out by looking at some of the basic requirements that you need in order to establish a network. Networks are simply made up of three basic things. You have to have your computer, within a computer you will have a network card and all of those network cards to communicate you will have to have some type of networking cable. Now let us start out with the computer sort of things. Basically your networked computer would have some sort of operating system running on them to have to have network capabilities and this is pretty easy as most of the operating systems out there today do support networks. Now the physical hardware inside the computer plays the role as well. Within your computer a little smart circuitry is called bus. A bus is basically the high way the data travels on. Your network card has this same data high way. Now interestingly enough inside of your computer almost everything runs in parallel which is side by side. So we might have several different lines of that data as it passes over the inside of the computer. Well unfortunately, networks generally run serially, which means they run in a straight line. So some how we got to be able to get that internal parallel data to a serial inline data on to the network. Well that's what the network cards can do for us. The network card is an extremely important part of a basic network. Now your cabling also known as media is also extremely important. Your network cards, your computers and your cabling all have to match up together for them to communicate properly. Network cabling can be as simple as going to the store and buying a three foot cable or can be as complicated as building your own cable and crippling your own ends. So we cover some of the basic media requirements also later on our lessons. So we got our computers, we got our network cards and we have got our cabling, So let us see what else we can do with this.
