Strategic Use of the Internet and E-Commerce: Cisco Systems
Journal of Strategic Information Systems 11 (2002) 5±29 www.elsevier.com/locate/jsis Strategic use of the Internet and e-commerce: Cisco Systems Kenneth L. Kraemer*, Jason Dedrick Graduate School of Management and Center for Research on Information Technology and Organizations, University of California, Irvine, 3200 Berkeley Place, Irvine, CA 92697-4650, USA Accepted 3October 2001 Abstract Information systems are strategic to the extent that they support a ®rm's business strategy. Cisco Systems has used the Internet and its own information systems to support its strategy in several ways: (1) to create a business ecology around its technology standards; (2) to coordinate a virtual organiza- tion that allows it to concentrate on product innovation while outsourcing other functions; (3) to showcase its own use of the Internet as a marketing tool. Cisco's strategy and execution enabled it to dominate key networking standards and sustain high growth rates throughout the 1990s. In late 2000, however, Cisco's market collapsed and the company was left with billions of dollars in unsold inventory, calling into question the ability of its information systems to help it anticipate and respond effectively to a decline in demand. q 2002 Elsevier Science B.V.

Introduction Information systems are strategic to the extent that they are used to support or enable different elements of a ®rm's business strategy (Porter and Millar, 1985). Cisco Systems, the world's largest networking equipment company, has used the Internet, electronic commerce (e-commerce), and information systems as part of its broad strategy of estab- lishing a dominant technology standard in the Internet era. -

This chapter will concentrate on the connectivity devices that define the network topology—the most important being the network interface card. We will also take a look at hubs, routers, and switches. Another important aspect of building your network is selecting the hardware for your client PCs and your network servers. There are many good primers on computer hardware—for example, the Absolute Beginner’s Guide to PC Upgrades, published by Que. Also, numerous advanced books, such as Upgrading and Repairing PCs (by Scott Mueller, also from Que), are available, so we won't cover PC hardware in depth in this chapter. We will take a look at motherboards, RAM, and hard drives because of the impact these components have on server performance. We will also explore some of the issues related to buying client and server hardware. Let's start our discussion with the network interface card. We can then look at network connectivity devices and finish up with some information on PC hardware. -

Cisco Systems (A): Evolution to E-Business
Case #1-0001 Cisco Systems (A): Evolution to E-Business "We view the Internet as a prototype of how organizations eventually will shape themselves in a truly global economy. It is a self ruling entity." —John Morgridge, Annual Report, 1993 Cisco Systems, says president and CEO John Chambers, is “an end-to-end networking company.” Its products and services enable the construction of corporate information superhighways, a driving concern of today’s CEOs, seeking to become “e-business” leaders in their industries. Defining “e-business” can prove more difficult than embracing it, however. In executive programs at the Tuck School, Professor Phil Anderson frequently asks participants, “How will you know when you have seen the first e-business within your industry?” Typically, there is little consensus. Is it mass customization? Streamlined production processes? One- to-one marketing? Cisco’s Internet Business Systems Group (IBSG), an internal consulting group, advises senior executives on information technology investment strategies. The group is closer to major corporate buying decisions than anyone at Cisco. As advocates for Cisco’s equipment, group members’ main struggle is identifying the benefits of becoming an e-business, which are wide, varied, and difficult to quantify. Additionally, the initial infrastructure investment is large enough to prompt many CEOs to wonder whether it’s really worthwhile to become an e-business. Trying to build a business case (calculate an ROI) for making a major IT investment can be an exercise in frustration. Says Sanjeev Agrawal, a director within the IBSG, “Can you show me the ROI of going to sixth grade? The amount of time it is going to take to try to go through the logic of that is not worth it.” The IBSG hopes that potential customers will look to Cisco as an example of how a company can make the most of information technology. -

5 Networking Hardware In the last couple of years, an unprecedented surge in interest in wireless networking hardware has brought a huge variety of inexpensive equipment to the market. So much variety, in fact, that it would be impossible to catalog every available component. In this chapter, well look at the sort of features and attributes that are desirable in a wireless component, and see several examples of commercial and DIY gear that has worked well in the past. Wired wireless With a name like “wireless”, you may be surprised at how many wires are involved in making a simple point-to-point link. A wireless node consists of many components, which must all be connected to each other with appropri- ate cabling. You obviously need at least one computer connected to an Eth- ernet network, and a wireless router or bridge attached to the same network. Radio components need to be connected to antennas, but along the way they may need to interface with an amplifier, lightning arrestor, or other de- vice. Many components require power, either via an AC mains line or using a DC transformer. All of these components use various sorts of connectors, not to mention a wide variety of cable types and thicknesses. Now multiply those cables and connectors by the number of nodes you will bring online, and you may well be wondering why this stuff is referred to as “wireless”. The diagram on the next page will give you some idea of the ca- bling required for a typical point-to-point link. -

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Multiple sequence alignment (MSA) of DNA, RNA, and protein sequences is one of the most essential techniques in the fields of molecular biology, computational biology, and bioinformatics. Next-generation sequencing technologies are changing the biology landscape, flooding the databases with massive amounts of raw sequence data. MSA of ever-increasing sequence data sets is becoming a significant bottleneck. In order to realise the promise of MSA for large-scale sequence data sets, it is necessary for existing MSA algorithms to be run in a parallelised fashion with the sequence data distributed over a computing cluster or server farm. Combining MSA algorithms with cloud computing technologies is therefore likely to improve the speed, quality, and capability for MSA to handle large numbers of sequences. In this review, multiple sequence alignments are discussed, with a specific focus on the ClustalW and Clustal Omega algorithms. -
