... addresses are hard to remember and are inconvenient to use. DNS allows us to use host names and domain names, which can represent IP addresses. DNS servers translate host names and domain names (for example, www.gc.peachnet.edu) to an associated IP address (for example, 192.168.1.10.) For example ... , peachnet Networks has registered the domain name "peachnet.edu" for use by our servers and others. The host names "mail" and "www" represent different servers registered in the same domain. A domain name is a computer name suffix shared by a group of computers in the same ... DNS informati...

... in existing networks. It can be used to aggregate traffic between clients and "server farms", and for connecting Fast Ethernet switches. It can also be used for connecting workstations and servers for high bandwidth applications such as medical imaging or CAD [1]. However, the increase in speed brings many changes to the original Ethernet standard, even though it maintains the same CSMA ... ETHERNET (IEEE 802.3z) The standard for gigabit Ethernet increases the speed of the original Ethernet to 1 billion bits per second (1000 Mb/s or 1 Gb/s) for interconnecting switches, routers, and ser...

... same type. Many switches today offer high-speed links, like Fast Ethernet or FDDI, that can be used to link the switches together or to give added bandwidth to important servers that get a lot of traffic. A network composed of a number of switches linked together via these fast uplinks is called a "collapsed backbone" network. General Benefits of Switching Since switches are self ... same type.

... of the largest and most common disadvantages are server failure and initial start up cost. When the server fails, the whole system is considered useless until the server is fixed. Servers can also be very expensive, ranging from $5000.00 to $150,000.00. Also, in order to cut down on server failure, special-purpose server software, hardware and expert staff ... ...

... different protocols. Protocols govern communication between different machines but at the same layer. The top layer is called the application layer. This layer allows two application programs that use different servers to communicate with one another. The transport layer allows two hosts to communicate with one another, regardless of the difference in their design. An example would be a desktop PC communicating ... ...
