Wired local area networks are transported over network cabling that runs throughout a building. Network cabling is set up in one of three physical topologies: Star In a star topology, a separate cable is run from a central location to each computer. This is the way that most networks are wired today. The central location might be a wiring closet or a computer room, where all of the cables from each computer would converge at one location and be connected to network equipment such as a switch or hub. Ring A ring topology consists of cabling that runs from one computer to the next. Early Token Ring and Ethernet networks were often wired this way. Where the network cable was attached to a computer, a T connector was used: one part connected to the computer itself, and the other two connectors were connected to the network cabling. Bus A bus topology consists of a central cable, with connectors along its length that would facilitate branch cables that would be connected to individual computers. Like the ring topology, this was used in early networks but is seldom used today. These three topologies are illustrated in Figure 5-13. It should be noted that the logical function and physical topology of a network might vary. For instance, a Token Ring network may resemble a physical star, but it will function logically as a ring. An Ethernet network functions as a bus, but may be wired as a star, bus, or ring, depending on the type of cabling used (and, as indicated earlier, star topology is prevalent). The point is that logical function and physical topology often differ from each other.

You can add, move, and delete fountain fill colors you ve added to a default fountain fill type in several ways, but you must have both the object and the Interactive Fill Tool selected, or you ll wind up editing the filled object and not the fill itself! To explore doing this, follow the steps in this tutorial.

Here s what these options offer control over:

2. Suggest that they look at combining categories to see if we can eliminate duplications and redundancies. By identifying the main categories and forcing myself to ll in the blanks, I was able to generate ideas. For example, the idea of combining categories to avoid duplications and redundancies I think that s a really good idea, and it only came to me because I needed a No. 2 to follow my No. 1. In the end, the E-mail just about wrote itself. (See Figure 2.1.)

Leased lines, fiber, and microwave each have benefits and drawbacks in terms of bandwidth, reliability, price, and delivery. The tendency is usually very applicationspecific. Every case is different in terms of terrain, line of sight, right of way, location of a Bell central office, and so on. A mile fiber choice can range in cost between $20,000 and several million dollars, depending on the terrain requiring traversal. Similarly, a high-speed leased line can cost $600 a month or $20,000 a month if it crosses LATA or other rate boundaries. No one solution fits all possibilities for connectivity. Using a wireless connection, the first, full-speed Ethernet speed solution was a major milestone. From this innovation, users had viable options, bridging the extremes between leased lines and fiber. Many users still limit their choices to the bottleneck of a T1 leased line or overpaying for a T3, which is too much bandwidth for the need. Instead, you should find a solution that provides the needed bandwidth for a justifiable cost. All three solutions offer high reliability for the most critical connections, although a mission-critical path must be backed up. Keep in mind also that the three choices are not mutually exclusive. They frequently work well together. Microwave handles last mile connectivity to a fiber backbone or serves as a lower-cost, automatic backup as insurance against backhoe fade. You should weigh each choice, based on which offers the best cost to benefit ratio. Cost includes installation, on-going charges, upkeep, losses due to downtime, and organizational productivity.

Gaining an executive sponsor and executive support is, without question, the single most important thing I did for this project. The challenges that followed during the next nine months would have been difficult, if not impossible, to overcome without the complete backing of the most senior folks in our company. Anthony Lackey, Vice President of MIS, Chief Technology Officer, ABM Industries Many people simply resist change, particularly if they feel they are giving something up. Executive sponsorship is essential for successfully transforming into an on-demand enterprise. Upper management must make it absolutely clear that the application delivery platform initiative is something that will happen and that everyone is expected to make work. Ideally, the CIO and other selected executives should begin using the new platform in order to show their complete support for the project.

If your intended applications are not too rigorous, bundled applications may comfortably satisfy your requirements, but rarely are the high-end professional-caliber applications included in bundles. If you have a clear sense of your objectives in recording and know which of the CD-ROM or DVD formats you want to be able to create, these factors will help guide your selection of an appropriate disc recording application.

At the bottom of the display, a D in the first column refers to an EIGRP route. In this example, there is one EIGRP route that was learned from 192.168.4.101. For an EIGRP route, you ll see two sets of values in brackets ([]). The first value indicates the administrative distance of the route (90) and the second the feasible distance of the router (the metric). Following this you can see the peer with which the route is associated, how long ago an update was received concerning this route or neighbor, and which local interface on the router to use to reach the neighbor. Notice that for network A D in the routing table 192.168.101.0/24 there are two successor indicates an EIGRP route. EIGRP has an routers with the same metric, which means the administrative distance of 90. router will load-balance traffic across these two paths to this destination. If you are not seeing EIGRP routes in the routing table for a peer, check the following on your router:
