The biggest difference is in how the two platforms use the network. When running a personal computer, often software applications are stored on network servers. When you activate an icon, the network pushes the executable down to your PC. Once downloaded into memory, the application runs and then very little interaction takes place until you save a fi le. Or in other cases, the executables are on the local PC, and network activity is not used until fi les are saved. If an executable takes a few seconds longer to download, you won't really notice it when using a personal computer. Some networking devices seem better designed for effi ciency of download instead of being designed for the smaller and more plentiful packets of network computing. When you activate a software application on a thin client, the presentation of the user interface is pushed to you from the server, and then all keystrokes and mouse activity are transmitted back and forth to the server in real time. The network needs to be very fast, have low latency, and be confi gured to pass packets immediately to the servers.
