Their money flows to high-end systems in the hope these computers will have a longer useful life. This strategy makes a lot of sense, because upgrading a PC is a time-consuming, costly exercise that almost always includes follow-up support calls. More important, savvy organizations know that less than 20 percent of the true life-cycle cost of a PC is reflected in its initial cost. There's a mountain of evidence to support this assertion, as well as the corollary that thin clients save money. For example, a survey of 25 sites using thin-client technologies conducted earlier this year by Datapro concluded that on average, deploying thin-client devices cut support costs by more than 80 percent.
VPN Introduction: VPN stands for Virtual Private Network. VPN is a data network connection that makes use of the public telecommunication infrastructure but maintains privacy through the use of a tunneling protocol and security procedures. It operates much like a Wide Area Network (WAN). Most companies actually leased lines, but in either case both solutions are very expensive. As the Internet became more widely available people started creating VPN solutions that took advantage of the cheap network access.
The driving force behind the Internet has been increasingly cheap, fast, and reliable connections between distant machines. As Internet connectivity increases, internetworking can be used in more places for more purposes. Until recently, businesses and consumers depended on modems to connect to the Internet, but now several new technologies are being used to continue the trend of greater connectivity. These include digital subscriber lines (DSL), cable modems, and fixed wireless networks. This paper briefly examines each of these new technologies.
However, the research suggests that there are disadvantages to some companies that would prevent them from supporting teleworking. The primary advantages include: • Improves employee satisfaction––employees tend to have more independence and find better work/life balance telecommuting. The majority of people (80%) see telecommuting as a job perk. Many would prefer telework over a pay raise (37%) and 36% would take a 10% pay raise to be able to work from home (Lister, 2016). • Reduces unscheduled absences––this benefit saves employers money.
WAN connectivity over distance often requires the use of regenerators and meet points between multiple Telco suppliers that may span the globe. Without strict adherence to standards, these connections would not function. WAN technologies depend on highly complex and expensive equipment, which can guarantee inter-operability and “five 9’s” reliability required to support the millions of paying customers utilizing the network. Meanwhile, the advent of early PC’s and the recognition of the value in networking devices together gave rise to Local Area Networks. These LAN’s were developed from a business customer perspective, which placed more emphasis on costs and ease of use over reliability.
Verizon Wireless cellular service is inelastic because the products and services it offers makes them the dominant leader in the wireless industry; therefore, a 10% change in calling plan prices (monthly access fees) would not affect the quantity demanded. Verizon Wireless can depend on this inelasticity in their pricing model because of the strength of its brand and the wealth of products and services it offers. Verizon Wireless' competitive advantage comes from its ultra-low churn rate (the percentage of customers who disconnect their service is less than one percent of its 60 million customer base). This indicator suggests that customers are satisfied with the service Verizon Wireless offers and a slight price increase probably would not drive its customers to the competition. This data also suggests that customers probably stay with Verizon Wireless because of its continued expansion of new technologies and services such as its all-digital nationwide CDMA network, EVDO' or its advanced data network (used to wireless send and receive email and other data almost anywhere in the US), and VoIP (Voice over Internet Protocol) that they use for their Push to Talk products.
A VPN can grow to accommodate more users and different locations much easier than a leased line. In fact, scalability is a major advantage that VPN's have over typical leased lines (dedicated circuits). Unlike with leased lines, where the cost increases in proportion to the distances involved, the geographic locations of each office matter little in the creation of a VPN. Descriptions / Types Virtual Private Networks allow enterprises to utilize cost effective, secure, and scalable hardware to extend their wide area network. These networks are cost effective in that they are able to connect remote users to the corporate network without the need for expensive dedicate WAN links or modem banks.
With respect to Audible.com, their market is selling audio content online. Supplier power for Audible.com is medium to high. The firm has an advantage with its partners who offer only specific products through Audible.com less expensively as compared to other companies or websites. However, some of the audio content is offered through many other websites and stores, which can be used instead of Audible.com. As a result, this pulls the firm’s power from the highest on the market to medium power.
Another problem in CCC's not-to-distant future is their distribution costs. With the use of the Internet, competitors have been able to ... ... middle of paper ... ...pr. 2000). This will lower costs and possibly increase the bottom line for the computer giant. Like IBM, Hewlett-Packard made one mistake and cost itself billions of dollars in revenues.
Disadvantages: Expensive because of the large number of cables and connections required. Reconfiguration of the network or the addition of another node impacts all of the other nodes. Bus Topology - All nodes are connected to a central cable called the bus or backbone. A node wanting to communicate with another node sends a broadcast message onto the central cable, but only the intended recipient actually accepts and processes the message. Advantages: Less expensive because it requires less cable and hardware than other topologies because all of the nodes are in a line and lie near the bus.
