Example text

Only then could hundreds of users print to a printer (or printers) simultaneously. Early LANs were small and isolated, and it wasn’t long before the need to connect them became apparent. As necessity is the mother of invention, wide area networking soon evolved. Minicomputers and shared wide area networks (WANs) were created to address these growing business requirements. Today, many businesses still have mainframe and LAN technologies working side by side. The migration of applications from central hosts to distributed servers has complicated computing needs considerably, resulting in new networking requirements and changing traffic patterns.

The answer to the problem is to have the receiving host acknowledge receiving each and every data segment. Data throughput would be low if the transmitting machine had to wait for an acknowledgment after sending each segment. But because there’s time available after the sender transmits the data segment and before it finishes processing acknowledgments from the receiving machine, the sender uses the break to transmit more data. How many data segments the transmitting machine is allowed to send without receiving an acknowledgment for them is called a window.

These addresses possess and convey important information about the path of media connections. They’re used by routing protocols to pass packets from a source onward to its destination. The Network layer creates a composite “network map”—a communication strategy system—by combining information about the sets of links into an internetwork with path-determination, path-switching, and route-processing functions. It can also use these addresses to provide relay capability and to interconnect independent networks.
