In addition torepparttar rubricator,repparttar 146268 new version of SearchInform featuresrepparttar 146269 automatic documents categorization system that automatically sorts new documents intorepparttar 146270 existing rubrics according torepparttar 146271 overall similarity principle. The proposed approach to organizing and consolidating data allows structuring informational components of any large enterprise withinrepparttar 146272 framework of one application. With all this you won't have to convert your documents and data into a single format. All information available for indexing and further search will be sorted, structured and displayed in a most convenient way. SeachInform provides prompt document search and structures data inrepparttar 146273 corporate network. It gives you power over information. It gives yourepparttar 146274 ability to act while other are still searching.

physical topology of a network refers to the configuration of cables, computers

The protocols used with star configurations are usually Ethernet or LocalTalk. Token Ring uses a similar topology, calledrepparttar star-wired ring. Star-Wired Ring A star-wired ring topology may appear (externally) to berepparttar 146211 same as a star topology. Internally,repparttar 146212 MAU (multistation access unit) of a star-wired ring contains wiring that allows information to pass from one device to another in a circle or ring (See fig. 3). The Token Ring protocol uses a star-wired ring topology. Tree A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable (See fig. 4). Tree topologies allow forrepparttar 146213 expansion of an existing network, and enable schools to configure a network to meet their needs. Advantages of a Tree Topology •Point-to-point wiring for individual segments. •Supported by several hardware and software venders. Disadvantages of a Tree Topology •Overall length of each segment is limited byrepparttar 146214 type of cabling used. •Ifrepparttar 146215 backbone line breaks,repparttar 146216 entire segment goes down. •More difficult to configure and wire than other topologies. 5-4-3 Rule A consideration in setting up a tree topology using Ethernet protocol isrepparttar 146217 5-4-3 rule. One aspect ofrepparttar 146218 Ethernet protocol requires that a signal sent out onrepparttar 146219 network cable reach every part ofrepparttar 146220 network within a specified length of time. Each concentrator or repeater that a signal goes through adds a small amount of time. This leads torepparttar 146221 rule that between any two nodes onrepparttar 146222 network there can only be a maximum of 5 segments, connected through 4 repeaters/concentrators. In addition, only 3 ofrepparttar 146223 segments may be populated (trunk) segments if they are made of coaxial cable. A populated segment is one which has one or more nodes attached to it . In Figure 4,repparttar 146224 5-4-3 rule is adhered to. The furthest two nodes onrepparttar 146225 network have 4 segments and 3 repeaters/concentrators between them. This rule does not apply to other network protocols or Ethernet networks where all fiber optic cabling or a combination of a fiber backbone with UTP cabling is used. If there is a combination of fiber optic backbone and UTP cabling,repparttar 146226 rule is simply translated to 7-6-5 rule. Considerations When Choosing a Topology: •Money. A linear bus network may berepparttar 146227 least expensive way to install a network; you do not have to purchase concentrators. •Length of cable needed. The linear bus network uses shorter lengths of cable. •Future growth. With a star topology, expanding a network is easily done by adding another concentrator. •Cable type. The most common cable in schools is unshielded twisted pair, which is most often used with star topologi
