The TCP/IP Guide - Network Structural Models and Client/Server and Peer-to-Peer Networking

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!

In a strict peer-to-peer networking setup, every computer is an equal, a peer in the network. Each machine can have resources that are shared with any other machine. There is no assigned role for any particular device, and each of the devices usually runs similar software. Any device can and will send requests to any other, as illustrated in Figure 5.

**Figure 5: Peer-to-Peer Networking**
In this model, each device on the network is treated as a peer, or equal. Each device can send requests and responses, and none are specifically designated as performing a particular role. This model is more often used in very small networks. Contrast to Figure 6.
