Advantages of the Internet in life globally
we talk about the Internet there's a couple of pieces of terminology
that I want to get straight right away there are three different words we're going to cover here Internet network and intranet which is the word that it's and it's related to what we're talking about it sort of
mixes in with the other two it could be a little bit confusing so, on one hand, we have computer networks those computer networks consists of computers that are physically connected together and their use so that might pay the question.
Days with internet technology
what is the internet so and why would we use these two terms at all why not just the Internet is a computer network but why would we still refer to computer networks separately and so the key distinction here is that when we talk about a single computer network we're really talking about usually administrative and control and maintenance of a particular network that is part of the broader Internet so for example in this building on this campus is the UB computer network that's a network that's administered installed maintained and to some degree.
installation of the computer network in different universities
I should say to some degree entirely funded by the University of Buffalo so they're paying for the installation of the computer network the maintenance of the computer network and that computer network is is sort of owned by them so you know here's, for example, you know you B's network campus network and you know down downtown there might be another there are other campus networks for the other universities in the area Canisius probably has its own campus network these are an example of different computer networks okay now.
word internet is actually short for internetwork
when we talk about the Internet the word Internet is actually short for inter Network so it's a connection of different networks the internet came about partially because there were existing computer networks and people wanted agreements about how those computer networks could connect to each other and build a much larger network that could exchange data and so you B's campus network is part of a broader Internet it is connected to other networks that are administered by other entities and those networks connected together connected together connected to each other form you know the broader Internet right so the Internet consists of all these computer networks UV might have one you know buff state has their own network I'm not sure these are directly connected together but when you think about all the different networks that are run by different companies different organizations all connected together across the world this makes up the broader Internet or the broader Internet work so we talk about the Internet we're talking about something that's much bigger than any organization much bigger than any country it's a agreement.
computer networks together to the broader internet
it's a global cooperative of networks that have decided it would be better if we all connected together so that we could exchange data with each other and we could bring you know billions of people online into the same computer network system when we talk about a computer network on the other hand we're usually talking about a network that belongs to it is maintained by a signal organization or a single entity the final word that mixes in a little bit here is internet and this word is probably the least interesting from our perspective because what an intranet really refers to is the fact that when organizations connect their computer networks together to the broader Internet they don't necessarily expose all of the information or all of the resources that are present within their own private computer network so UB might say for example I agree to be part of the broader Internet because it's super useful for computers that are connected to my network to exchange data with all the other computers on the Internet however I have some private internal websites that are for faculty or staff views that are not appropriate to expose to the broader Internet and those resources and know that those resources can be computers those resources can be data those resources can be various services make up what is called an intranet so intranet refers to the fact that unless you are physically connected to a particular computer network there are certain resources that may not be available to you so three terms intranet not necessarily super related to what we're doing Internet work or Internet a network of computer networks that agree to exchange data in common ways and a computer network referring to a single computer network computers that are physically usually connected together operated maintained by a single organization or entity
