Search as you type. It’s a simple and straightforward idea—people can get results as they type their queries.

Cisco and Citrix Systems said Wednesday that they will collaborate on desktop virtualization tools to ease deployments.

So now that we’ve determined that Google Instant is a time saver, giving back anywhere from 8.3 minutes to 20.8 minutes per week to users who conduct 50 Google searches per day, Larry Dignan and I started to have some fun, experimenting with the searches themselves.

The technology, 'Ethernet' at the early age was quite simple. As it was developed much before the advent of 'Microprocessor', the whole technology was much more less demanding to intelligence of the network structure and the workstations.

At the very top of the OSI Reference Model stack of layers, we find layer 7, the application layer. Continuing the trend that we saw in layers 5 and 6, this one too is named very appropriately: the application layer is the one that is used by network applications.

The presentation layer is the sixth layer of the OSI Reference Model protocol stack, and second from the top. It is different from the other layers in two key respects. First, it has a much more limited and specific function than the other layers; it's actually somewhat easy to describe, hurray! Second, it is used much less often than the other layers; in many types of connections it is not required.

The fourth and “middle” layer of the OSI Reference Model protocol stack is the transport layer. I consider the transport layer in some ways to be part of both the lower and upper “groups” of layers in the OSI model.
