hether it s for personal pleasure or selling your wares, the Web is your connection between your ideas and your business and social contacts. It s far less expensive than other publication media such as television and print, and the really great thing about it is that it s hot. The good news is that you don t have to be a rocket scientist to get media up on your website using CorelDRAW, and the better news is that once you ve designed a piece for print, it s practically ready to go on the Web. Create once, publish many times! In this chapter you learn about the many tools and features at your disposal in CorelDRAW for optimizing your work for the Web, and about how to create special web graphics such as rollover buttons that turn your art into interactive art.

When the Seven can articulate his or her responsibility, ask questions to elicit more depth and insight, as well as discussion of how this information can be useful going forward.

Console.WriteLine("\nFail with error reports."); for(int i=0; i < (fs.Length * 2); i++) if(!fs.Put(i, i*10)) Console.WriteLine("Index " + i + " out-of-bounds"); for(int i=0; i < (fs.Length * 2); i++) { x = fs.Get(i); if(x != -1) Console.Write(x + " "); else Console.WriteLine("Index " + i + " out-of-bounds"); } } }

The following outlines all the different components and server roles necessary for an Access Gateway Advanced Access Control deployment. Depending on the size of the deployment, many of these components can run on the same server.

optimized to handle voice traffic (which almost always means telephony traffic traffic originating and terminating on a telephone). Offering data solutions, therefore, meant transporting bursty, packet-based traffic over a voice-based infrastructure using Time Division Multiplexing (TDM) technologies (see chapter on TDM for an explanation of TDM) such as the T-carrier (T-1, T-3, etc.) on copper and fiber, and SONET (Synchronous Optical NETworking) rings over a fiber infrastructure. However, as traffic data (essentially non voice; could be anything like email, file transfers, etc.) began to reach a critical mass, alternative (and most often separate) packet-based network infrastructures were developed to carry data traffic (i.e., offer data services). Initial packet services used a technology called X.25 quite extensively. X.25 was an ITU standard that enabled packet transmission at speeds between 2.4 and 4.8 Kbits/sec over traditional telecommunication networks; it was subsequently supplanted by other technologies, the more prominent being Frame Relay, Asynchronous Transfer Mode (ATM), and even traditional TDM (modified to be more efficient). And, as mentioned previously, Ethernet had also been used to offer data services as well. These services were delivered over a host of transport infrastructures or natively. Over the years, SONET-based TDM networks have the become dominant transport infrastructure, especially with the relatively increased deployment of fiber in metro and much more extensively in core networks. Table 1.4 provides a brief comparison among ATM, Frame Relay, traditional TDM, and Ethernet. A typical (albeit partial) telecommunications transport infrastructure is shown in Figure 1.9. Although specific implementations vary across different telecommunication

creates a double variable called version that contains the value 3.2 and that value cannot be changed by your program. The variable can, however, be used in other types of expressions. A const variable will receive its value either from an explicit initialization or by some hardware-dependent means. Applying the const qualifier to a variable s declaration ensures that the variable will not be modified by other parts of your program.
