The RIP Routing protocol (Routing Information Protocols) is the most widely used distance vector protocol. It was developed by Xerox in 1970s. At that time, RIP was part of the Xerox Network Service (Xerox Network Service) protocol cluster. The TCP/IP version of RIP is the license version of Xerox protocol. The biggest

routing algorithms into DV and LS. The DV (distance, Distance Vector) algorithm transmits the route information of the current router to the adjacent router. The adjacent router adds the information to its route table. The LS (link state) algorithm transmits the link state information to all routers in the domain, and the receiving router uses this information to build a network topology, the shortest path Priority Algorithm in graph theory is used to determine the route. In contrast, the Dista

In 1970s, when Xerox (Xerox) sent an image laser printer to the AI lab, it was found that only on the ninth floor of the AI Lab, to locate the location. All people in the building need to give instructions on their computers to ask the printer to help you. The printing speed is satisfactory, but sometimes th

If Windows is in the "Wintel standard" way, because you can use the mouse to click on the button to operate, very intuitive. DOS does not have a GUI, so he can only enter commands. This interface of DOS is called the cui (command line User Interface) command-line mode of the human-computer interface.

When an intranet is connected to the Internet, it is possible to have a physical connection with 50,000 of unknown networks and users, opening these connections to use a wide variety of applications and shared information, although most of the content is certainly not shared with the outside world, and the Internet provides a vast space for hackers to steal information and disrupt the network So security becomes a concern for connecting to the Internet.

themselves (such as twisted pair), but are affected by the surrounding environment. Because of the metal around UTP, hidden "ground", the construction of the pull, bending and so on will damage its balance characteristics, thereby reducing EMC performance. In fact, the cable that we install usually wears it into a metal conduit, a plastic conduit, or other protection with a different grounding impedance. S
flexibility of traditional and air blown fiber systems directly affects the cost of the whole system. The use of gas-blown optical fiber system, if the two points between the pipeline can not be installed optical fiber. As with traditional optical fiber systems, there is no fiber to install new fiber. However, as described in the design chapter, if a redundant link is installed as part of the traditional wiring design, the use of a patch or network switch can be very easy to resolve the various
directly access hardware devices to achieve better performance. Nonetheless, MS-DOS has become the most commonly used operating system on IBM PCs (IBM itself has introduced DOS, called Ibm-dos or Pc-dos). MS-DOS's success has made Microsoft one of the most lucrative companies on the planet.
And the 1980 's another rising operating system is Mac OS, which is tightly bundled with Macintosh computers. At this time a Xerox Parooto Research center employ
parts: serviceinfo and service itself. ServiceInfo functions like WSDL, containing information such as interface information, bindings, Endpoints (EndPoint), and services that contain information such as serviceinfo, data binding, interceptors, and service properties. You can use Java Classes and WSDL to create services. Typically, the front-end is responsible for creating the service, which is done through servicefactory.5. Bindings (binding)Bindings provide a way to map specific formats and p

IOR. Many ORB vendors provide a utility to look inside the IOR. Orbacus (see references) of OOC (object oriented concepts, Inc.) comes with iordump.exe. If you use VisiBroker, it provides printior.exe. You can also find a utility on the Xerox PARC site (see references. Because orbacus is being used, I will run iordump on the IOR created in the simplecalc example. The following output is displayed:
