FDDI's emergence as a networking interface standard is assured given its adoption across both Token Ring and TCP/IP-based networks and heterogeneous LANs that rely in large part on Fiber Optic cabling to ensure the highest level of performance possible.
Fiber optic cablings' unique set of advantages makes this specific type of connectivity solution ideal for high bandwidth requirements of LANs and WANs that transmit voice and data as the majority of their traffic. It departments that choose to implement Fiber Optics as their backbone cabling standard often include a series of repeaters to ensure the signals sent are strengthened before they reach their destination system. The development of cabling techniques for allowing for synchronous communication is also significantly changing how fiber optic cabling is used.
The role of fiber optic cabling in the creation of networks is clearly seen in the context of the OSI Model. The Data Link layer of the OSI Model is where Fiber Optic cablings' specifications are defined and included as part of the broader protocol stack. The introduction of high speed interfaces that capitalize on the unique strengths of Fiber Optics communications, including FDDI, are becoming increasingly commonplace in telecommunications, high-speed Internet, and high bandwidth-based application areas. The use of Fiber Optic in both CSMA/CD and CSMA/CA-based network topologies also is a direct result of the cablings' adoption in the faster token ring networks that operate at 16 Mbps, versus the 10 MBps that many TCP/IP-based networks run on. The ability of FDDI interfaces to intermediate between CSMA/CD and CSMA/CA is a major technological gain for the technology and its ability to work in multiple networking protocols and resulting operating systems as well. Further, the innate advantages of Fiber Optic to intermediate accentuation of signals and also provide a more accurate signal also makes Fiber Channel ideal for high bandwidth requirements of integrated voice and data networks.
The higher the bandwidth, the greater the reliance on more efficient and streamlined interface technologies. FDDI will most likely see performance gains as an interface standard given the increasing demands of applications that include streaming video and intensive VoIP-based applications. As more and more copper-based backbones are being replaced with FDDI, there will be an increasing focus on how to create the highest level of performance possible for all forms of digital content accessible over the Internet as well. Fiber optic cabling is ideally suited for the specific requirements of how larger enterprises will be using the Internet and their own content management systems in the future as well. The role of digital asset management, digital content management, the enterprise integration of these two systems and the resulting repositories of digital content (all forms) also is a market dynamic that will favor the development of increasingly sophisticated approaches to the development new, accentuated interfaces that realize the full potential of Fiber Optic cabling in high bandwidth environments. Finally, the use of fiber optic cabling to traverse larger enterprise LANs and WANs is an evolving trend on metropolitan area networks, especially in those businesses that rely on a single database for the majority of the information needed to run their business models. The entire concept of having a 360 degree view of both customers and the market is also predicated on high bandwidth speeds of all forms of digital content, and this market dynamics is revolutionizing the use of fiber optic cabling as well.

In choosing to define standards and frequency spectrum levels of this stands, the IEEE LAN/MAN Standards Committee chose to define a very broad public spectrum, which would allow for more efficient use of the standard for LA and WAN deployments. The IEEE Standards Committee defined the range of 2.4GHz to 5 GHz as the public spectrum band that could be accessed and used for over-air modulation and demodulation. WiFi is
Benefits and Disadvantages of Using Fiber Optics for Communication There are a variety of benefits and disadvantages to using fiber optics for communication. The primary benefit of fiber optics is its bandwidth capacity. Optical signals have a much greater capacity for information than electrical signals. Scocco (2006) notes that the most advanced copper cables can only carry 1 GB/second. Optical fibers can theoretically carry 350 TB/second (350,000 GB/second). Even though this
Wireless Network Design Proposal Apparently, technology has influenced many fields and education is not an exception. Students can now access education from different locations in the globe, a factor that has contributed to the development of the education sector. In addition, students can access lectures through the internet, lecturers can share information through live-conferencing, and this has led to further development of the education sector. The case study provided aims
Modern technology however has enabled ion-exchange techniques allowing manufacturers to prepare erbium for commercial purposes (Wiki 1). There are many commercial and non-commercial purposes for erbium today. Its uses include use as a photographic filter and "as a dopant in fiber optic laser amplifiers" (Wiki 1; Mears et al. 1026). A compound of erbium, "erbium oxide" is often pink in color and has various uses commercially including coloring glass or

HTTP, on the other had, is a protocol that is used to request and deliver files such as Web pages and Web page components. When a browser requests a Web page from a Web server, it uses HTTP. 14.

76). As automation increasingly assumes the more mundane and routine aspects of work of all types, Drucker was visionary in his assessment of how decisions would be made in the years to come. "In the future," said Drucker, "it was possible that all employment would be managerial in nature, and we would then have progressed from a society of labor to a society of management" (Witzel, p. 76).
