Please Whitelist This Site?
I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)
If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.
If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.
Thanks for your understanding!

Types and Sizes of Networks
One of the reasons that understanding
networks can be difficult at times is that there are so many different
types! When someone talks about a network, this can mean
anything from two computers hooked together in an apartment to a globe-spanning
entity with millions of nodes. Every network is unique, and each one
has an important role to play in filling the communication and data-sharing
needs of different individuals and organizations. In fact, the great
diversity and flexibility of networking is one of its most important
In this section I describe the major
types of networks that exist by drawing distinctions between them based
on their size and scope, and show how each type and size is used. I
begin with a discussion of LANs, WLANs and WANs, and a few variations
on these three main categories. I explore the many terms that are related
to the various sizes of networks and how they are used, including segments,
subnetworks, internetworks, intranets and extranets
Note: As with other networking fundamentals discussions, if you have some background or experience in networking, you may not need to read everything in this section. I'd suggest scanning the headings of the various topics here to get a handle for what you feel you need to read.
