    Networks provide efficiency in the hospitality industry on a multitude of platforms. They are useful to the resort itself, who can connect and make reservations, check guests in, allow guests to charge food or additional items to their rooms, and provide service for any additional guest needs. For guests they can make reservations, learn about the hotel, and be connected and feel at home even away from home. More than that, networks can connect in the article posted and provide security, connecting the entire resort. For example, if there is an emergency the network can link to all rooms and set off the alarm to inform the guest.

What Is Cloud Computing? A Beginner's Guide | Microsoft Azure - 0 views

  • Top benefits of cloud computing Cloud computing is a big shift from the traditional way businesses think about IT resources. Here are seven common reasons organizations are turning to cloud computing services: Cost Cloud computing eliminates the capital expense of buying hardware and software and setting up and running on-site datacenters—the racks of servers, the round-the-clock electricity for power and cooling, and the IT experts for managing the infrastructure. It adds up fast. Speed Most cloud computing services are provided self service and on demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning. Global scale The benefits of cloud computing services include the ability to scale elastically. In cloud speak, that means delivering the right amount of IT resources—for example, more or less computing power, storage, bandwidth—right when they’re needed, and from the right geographic location. Productivity On-site datacenters typically require a lot of “racking and stacking”—hardware setup, software patching, and other time-consuming IT management chores. Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals. Performance The biggest cloud computing services run on a worldwide network of secure datacenters, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate datacenter, including reduced network latency for applications and greater economies of scale. Reliability Cloud computing makes data backup, disaster recovery, and business continuity easier and less expensive because data can be mirrored at multiple redundant sites on the cloud provider’s network. Security Many cloud providers offer a broad set of policies, technologies, and controls that strengthen your security posture overall, helping protect your data, apps, and infrastructure from potential threats.

Investing in Technology for Competitive Advantage / Arthur Andersen / Fall 1996 - 1 views

  • Today's hospitality industry technology represents a legacy reflecting the computer industry's capabilities during the last two decades and the willingness of hotel executives to embrace its products
  • critics have been increasingly harsh with their comments on the computer systems and software applications used by the hospitality industry. Typically custom-designed for proprietary application, these systems have not always been successfully integrated
  • The question for many hotel organizations remains how to achieve the ultimate open system that can be shared at all levels, whether it is the central reservation system, individual property management system or any other operational area
  • ...3 more annotations...
  • Timing is everything in technology investments
  • Network computing has enormous implications for marketing to customers on a global basis, as well as hotel operations. Consider the potential for the industry to connect with vendors worldwide for electronic purchasing, potentially achieving economies of scale and leveraging not yet possible. World purchasing functions will allow companies to customize their own catalogs. Virtual channels of distribution using computer networking capabilities will also allow hotel companies to market products and services - some traditional to our industry, others not - to customers whether they are in the hotel, at work, or at home. This will require a migration from today's central reservation systems to tomorrow's customer information systems using network-centric solutions. Development of customer profiles and guest recognition will make it possible for hotel organizations to interact in entirely new ways with customers, regardless of their physical location. Clearly, the large hotel companies will need to be the first to address questions raised by global networking capabilities and what this will mean in terms of technology investment. But for many hospitality companies presently struggling with the high cost of technology and the confusing state of our industry's technology affairs, this will not be an easy task. And the decisions will ultimately become further complicated by the opportunity to outsource certain functions into subscription-based networks. It is unlikely that the hospitality industry will be forced to bear the entire burden for networking infrastructure. Strategic alliances with major technology companies will be the catalysts in building this capability as they become strategic providers of networking capabilities to hospitality and other industries. And as network-centric computing comes of age and a company's proprietary information is stored in cyberspace, security will become an ever-more important issue requiring solutions. Whether it is an e-mail gateway through an internal network or customer access via the Internet, network fire walls and encryption systems will be required to mitigate the concern many will have with system security.

In the final analysis, networking solutions will drive down the cost of technology investment "on-property" where hotel real estate and business interests merge. The solutions that hotel organizations will be able to choose from in terms of networking should also be less expensive than the current profile of technology spending. And we can expect that change to occur sooner rather than later, given the present rate of investment in Internet-based technologies.

    "Investing in Technology for Competitive Advantage - The Challenge Facing the Hospitality Industry" sheds light on how the necessity of the investment in technology is in the hospitality industry. Not investing in technology affects even the customer services. It is mentioned that there are at least 85 property management systems available offered to owners and managers of hotels by technology providers which tend to meet the real needs of those. Further, open system that could be widely used is needed to acquire by hotel organizations. The more creative hospitality organizations are, the more successful would be in future. It is also indicated the technology cycles. Simply, technology would be increasingly required in future because of that the investment in technology would give a lot of opportunities to different parts in this industry.

    Investing in the hospitality industry as it relates to information technology is one of the ways the industry will stay current and be able to compete in this fast pace environment. More and more guest are demanding exceptional, cutting edge customer service. As this investment occurs there needs to be integration of hardware and software for the future. These choices are not easy and is perhaps one of the greatest challenges that the industry faces. Timing and knowledge is critical to investing in technology because innovation is moving so fast, therefore knowing what new development to purchase and the ability to integrate existing systems into new one is important. In conclusion, it is paramount for investors to be mindful of the market place and to get as much inputs into the decision that is made for maximum results.

The main function of a telecommunication network is to provide efficient and effect transmission of information. A telecommunication network can set up as WAN and LAN. A telecommunication set up as WAN allows reliable communication between nodes that are geographically located across large distance. Hotels chains that located in different area would like to use this network model. With the same level of security, a telecommunication network set up as LAN is used on a smaller geographic area. It provides phone, data, and internet within an enclosed setting. One example is a hotel, where the phones and internet access are all routed through a network located within a hotel. As technologies continue to advance, the definition and the scope of the telecommunication network will also continue to change. But what will remain the same is the core concept. Before I read this paper, my opinion on a telecommunication network is always indicates telephone service, and now I understand it also include internet, microwave and wireless equipment. I have to say that technology have been changed very fast so that we must keep in mind to update our knowledge on these new technology as well.

    In this paper a computer network is defined to be a set of autonomous, independent computer systems, interconnected so as to permit interactive resource sharing between any pair of systems. An overview of the need for a computer network, the requirements of a computer communication system, a description of the properties of the communication system chosen, and the potential uses of such a network are described in this paper.
  •  
    The goal of the computer network is for each computer to make every local resource available to any computer in the net in such a way that any program available to local users can be used remotely without degradation. That is, any program should be able to call on the resources of other computers much as it would call a subroutine. The resources which can be shared in this way include software and data, as well as hardware. Within a local community, time-sharing systems already permit the sharing of software resources. An effective network would eliminate the size and distance limitations on such communities. Currently, each computer center in the country is forced to recreate all of the software and data files it wishes to utilize. In many cases this involves complete reprogramming of software or reformatting the data files. This duplication is extremely costly and has led to considerable pressure for both very restrictive language standards and the use of identical hardware systems. With a successful network, the core problem of sharing resources would be severely reduced, thus eliminating the need for stifling language standards. The basic technology necessary to construct a resource sharing computer network has been available since the advent of time-sharing. For example, a time-sharing system makes all its resources available to a number of users at remote consoles. By splicing two systems together as remote users of each other and permitting user programs to interact with two consoles (the human user and the remote computer), the basic characteristics of a network connection arc obtained. Such an experiment was made between the TX-2 computer at Lincoln Lab and the Q-32 computer at SDC in 1966 in order to test the philosophy.' Logically, such an interconnection is quite powerful and one can tap all the resource of the other system. Practically, however, the interconnection of pairs of computers with console grade communication service is virtually useless. Firs

    This article was divided into five parts to introduce the computer networks. The first part is why do we need computer networks. I guess there are a lot of reasons ,but the most important one is to share information from others,everyone can visit information which is provided by other users,also they can simply access the same server machine. The second part is types of computer networks. It can divided by three different types 1.LAN when a certain number of computers within an organization are connected with the use of data transfer cables, it is called Local Area Network. 2.WLAN the goal of LAN and WLAN is same ,that is connect computers with networks.But cables are not used for forming the network. 3.WAN it can connect computers all over the world. The third part is computer network connections 1.Bus network .It is the easiest setup technology which is also easier to make mistakes 2 Star network. It is also a common setup technology 3.Mesh network. This is one of the primitive ways of forming a computer network The fifth part is information transformation . Using this technology, the data is broken into small pieces called packets of data. Every packet of data, has a head and in some cases a tail. The head contains various information, like the destination address, the checking bits. The final part is the definition of protocol. The computer protocol is a set of rules ,information travel from one to another. These set of rules will define, when to send a packet of data, when an acknowledgment signal should be given.The most common protocol, that we must have heard and which is used over in the largest network

  • With the world becoming ever more reliant on IT, from computers and laptops to smartphones, the issue of how you make it more sustainable, in terms of reducing energy requirements and electronic waste, becomes ever more pressing.
  • In 2010, it was estimated that 360 million computers were manufactured. A computer is one of the most resource-intensive pieces of equipment, requiring over 10 times its weight in fossil fuels to make
  • The production of a computer requires 22kg of toxic chemicals, 240kg of fossil fuels and 1,500 kg of water. 80% of life-cycle energy use is accounted for before we even switch a PC on for the first time. Computer Aid International About 2% of the world’s total energy is consumed by building and running computer equipment. BBC Office equipment is the fastest growing energy user in the business world, consuming 15% of the total electricity used in offices. This is expected to rise to 30% by 2020. In the UK, the cost of running this equipment is estimated to be around £300 million annually and rising each year. Carbon Trust 200 million computers and 550 million mobile phones reached the end of their life in 2008.  Computer Aid International 50 million tons of e-waste was generated worldwide, but only 13% was recycled. US Environmental Protection Agency Reusing working computers is up to 20 times more energy-efficient than recycling them. Computer Aid International

  • A data centre is a facility used to house computer systems and their components, and it can be far and away the biggest contributor to an organisation’s carbon footprint. A data centre’s life expectancy is relatively long so it is imperative it is built to the highest standards in terms of efficiency as any excess energy use will lead to significant cost implications over the years.
  • 1. Build the most energy-efficient data centre possible. This will save energy and costs over its lifespan. 2. Only get the data storage capacity that is currently required and forecast for the lifespan. Many data centres have excess capacity that burns energy (and therefore costs) unnecessarily. Don’t have servers or equipment that will not be used. 3. Cooling data centres. Traditionally cooling has been done by air circulation, which is very inefficient. Larger data centres already use other technologies to cool more efficiently, such as water cooling. 4. Virtualisation technology. Improve your system’s resource utilisation through virtualisation technology. Virtualisation is the creation of a virtual (rather than actual) version of something, such as an operating system, server, network, etc. and allows a single user to access several physical devices on one terminal. A computing device dedicated to an individual member of staff or allocated for one software application is highly inefficient and expensive. Virtualisation consolidates resources, requiring less power and cooling. 5. Consider cloud computing. This is a location-independent IT service, typically available over the internet, where shared servers provide resources, software and data to computers and other devices on demand, increasing IT capacity and capabilities without an organisation having to invest in new infrastructure. Keeping data virtually, or “in the clouds”, means less information stored on IT systems and therefore less energy being used to run the systems. Systems such as BT’s Virtual Data Centre, a hosted data centre that enables businesses to create, deploy, monitor and manage their own service through a self-service portal, claim to offer savings of up to 40% of the total cost of running one’s own data centre as well as reducing the space required, the level of emissions produced and the power consumed.
  • 6. Measure and monitor power usage. Once you know what’s using the power, focus on why and whether it’s possible to reduce consumption.
  • 1. Upgrade. Before buying new, investigate options to upgrade with the latest energy-efficient components to extend appliances’ working life and efficiency. 2. Green labels. Look out for the certification labels denoting more energy-efficient equipment, from Blue Angel in Germany to TCO in Sweden and Energy Star in the US (see below). 3. Screens. Opt for flat screen monitors, which reduce energy use by over two-thirds. 4. Get the right equipment. Consider your information technology needs against the tasks required. For example, laptops may be a better option in some circumstances because they have been developed to be energy-efficient and generally match the computer to the task required. Remember: not all staff have the same needs. 5. Consider running costs. Look at the life cycle costs, not just the purchase cost. Take note of running and standby costs of equipment. These can vary enormously.
  • Top 10 Tips to reduce running costs of office equipment (source: Carbon Trust) 1. Computers. Activate energy-saving features. In fact, most office equipment will have these features, so make sure they’re activated. 2. Standby features. Introduce a policy to activate standby features, don’t assume employees will do it. 3. Turn it off. Buy seven-day timers. These can save up to 70% on energy costs. 4. Monitor and manage the equipment that is peripheral to computers, such as speakers, printers, etc. and consider installing intelligent switch-off solutions. Printers can consume 30%-40% of their peak power demand when idling between printing and standby modes, so minimising this can produce cost savings, reduce heat output and increase its operating life. 5. Educate your staff. Consider a screen saver with an energy-saving message. 6. Rationalise your equipment via networking to reduce the number of printers (for example) in any office area. 7. Printers Use only black and white for internal documents and colour only when absolutely necessary. Consider the benefits of inkjet printers v laser printers. Inkjet energy use is much lower than that of a laser printer. Encourage staff to use print preview functions. Set default printing mode to double-sided. Use lower-specification printers, such as inkjets, for internal documents and encourage staff to use these for day-to-day use.
  • 8. Photocopiers High volume copiers use more energy so should be used sparingly. Use low melting point inks (available from stationery suppliers). Encourage staff to copy in batches to increase standby time. Stick to black and white copiers and only use colour when absolutely necessary. Set default copying to double-sided. 9. Invest to save and purchase only what you need. 10. Don’t forget to motivate staff. Keep repeating the message of the importance of energy saving in ways that they can understand (for example, a computer monitor switched off overnight saves enough energy to microwave six dinners).
  • WEEE (Waste Electrical and Electronic Equipment), or e-waste, is the term used for old or disposed electronic equipment. It covers both the toxic and valuable materials found in appliances. The most important lesson is to reuse, not recycle. With so much e-waste, and electrical devices such as computers and flat screens often being replaced well before the end of their shelf life and ending up in landfill, it’s imperative that the most is made of these materials by reusing them productively.
  • Options to investigate when trying to reduce e-waste are: 1. Can you upgrade your equipment with new energy efficient components? 2. Can it be used by someone else in the company? 3. Can it be given to a charity? (Note: charities must be registered to take WEEE.) 4. Will the manufacturer take back the old equipment and reuse parts in new products?
  • Developments on the horizon include: 1. Smaller, more efficient processors. The continuing development of microprocessors means a mobile phone can have around the same computational power as the average desktop computer back in 2000. 2. Memristors. Electronics giant HP is in the process of developing “memristors” (see photo above), which have greater memory storage capacity while requiring less energy and space. They are due to be on the shelf in about three years. 3. Specialist data centre design. Siemens recently launched its transformational Data Centre Solution, a groundbreaking strategy in data centre energy-efficient design and operation. It claims the system, which uses virtualization and efficient power and cooling, offers many benefits for businesses, including up to 50% energy savings through ground water cooling and IT costs reduced by 30%. 4. Outsourcing. Hotels of all sizes are starting to view IT outsourcing as a viable option to gain flexibility and reduce short-term costs and increase transparency of cost structures and processes. 5. Optimisation of resources. This will become a necessity either through virtualisation, networking or cloud computing. 6. Water cooling. IBM is currently working on a supercomputer that is cooled by water (a given volume of water can hold 4,000 times more waste than air), which claims to be 50% more energy efficient than the world’s leading systems. The Aquasar stacks many computer processors on top of each other with cooling water flowing between each one. IBM’s Dr Bruno Michel told the BBC in November 2010: “We plan that 10 to 15 years from now, we can collapse such a system into one sugar cube — we’re going to have a supercomputer in a sugar cube.”

Taking Network Security to the Cloud - 1 views

  • The biggest threat to network security at the hotel property level isn’t a lack of technology – it is the lack of resources to manage it.  A strong network security solution should combine cloud-based security configuration with plug and play installation of a firewall and IPS appliances.
  • The impact of a mass security approach is significant to hotel network operations. It could eliminate the need for on-site IT resources to configure and deploy security appliances. It could also provide much-needed network visibility across an entire portfolio of properties. Lastly, it would be instrumental in expediting large-scale security deployments and updates.

    Today's travelers expect a strong network security. The challenge is that many hotels lack the IT resources because of budget. As a result, IT functions are limited to making sure security patches are up to date and services are running rather than proactively identifying security threats and preventing. This article introduces cloud-based security system as a solution. With the network security system, IT headquarters can monitor and manage the entire network. Also, hotels can save the cost for on-site IT resources and security appliances. It was interesting that cloud-based security is a solution for network security when there are many opinions that cloud computing is not safe.

    This article talks about the limitation of hotel network security issue, then introduce one solution to it. First of all, it mentions since the usage of Internet is growing big more than ever, customers has more attention and requirement on Network Security. Actually, staff of IT department spend most of their time on updating system and other mid-level support, while they should spend more time on proactively identifying security threats and preventing attacks. This happens due to finance and human source constraints. Lucky for us, there is already one effective solution, keyword, cloud computing. Buy applying cloud computing, IT staff only need set up firewall, configure security system on headquarter. After then configuration is done, they send out these IPS device to branch companies. The security system will automatically update through these devices, no more traveling between properties.

    While many hotels right now are keeping and tracking down their valued customers' information, lots of those hotels are facing security problems also. Customers expect ironclad security that protects their entire "online" experience in the hotel, from online booking and iPad-enabled check-in to the wireless connectivity in their rooms. In today's cyber threat environment, that makes the hospitality industry a desirable and lucrative target for attacks. This article mainly talked about how to strength hotel network security.It suggested that a strong network security solution should combine cloud-based security configuration with plug and play installation of a firewall and IPS appliances. Which can be described as Taking Network Security to the Cloud.The IPS device will automatically contact and authenticate to the installation cloud, retrieve its configuration, and then reboot into the hotel's network ready to protect.

  • According to analysis of Shamoon by computer security firm Symantec, the way the virus gets into networks may vary, but once inside it tries to infect every computer in the local area network before erasing files to render PCs useless.
  • Yet those sources say such protections could not prevent an attack by an insider with high-level access.
  • insiders were implicated in just 4 percent of cases last year.
  • Saudi Aramco has said that only office PCs running Microsoft Windows were damaged. Its oil exploration, production, export, sales and database systems all remained intact as they ran on isolated and heavily protected systems.
  • Because the virus wiped the hard drives, it is difficult for Saudi Aramco to determine exactly what information the hackers obtained.
  • The Shamoon virus is designed to attack ordinary business computers
  • . It does not belong to the category of sophisticated cyber warfare tools
  • The hackers behind the Shamoon attack siphoned off data from a relatively small number of computers, delivering it to a remote server
  • It is standard industry practice to shield plant operating networks from hackers by running them on separate operating systems that are protected from the Internet.
  •  
    Saudi Arabias national oil company, Aramco, was attacked by a computer virus, Shamoon, and it is suspected that an insider or employee assisted the hackers. The virus spread through the network and infected about 30,000 PC business computers and wiped their hardrives. This is one of the worst attacks against a single business. The hackers who claimed responsibility, The Cutting Sword of Justice, were politically motived. The companies more important documents including plant operating networks were not affected by the virus because they were on a separate and higher security network. Recently, other Middle Eastern natural gas firms with relations to Saudi Arabia have been hit by cyber attacks. Because the Aramco hackers admitted their motives against the Saudi Arabian government income sources, I think that all the cyber attacks may be politically motivated. As a Middle Eastern oil company with relations to Saudi Arabia, this is a major indication to take precautionary measures and increase network security. This attack demonstrates that no matter how much security you have in place, if an insider is willing to assist hackers or provide hackers with necessary information, you are no longer protected. It would seem imperative that employees with this access are chosen carefully or network access is very limited.

    Having a good network security eliminates viruses and you are less vulnerable to identity theft or malware that can ruin your data. It is good t run regular weekly scans to ensure that your machine is not infected. It is also good to update the anti-virus programs and the operating systems to ensure that you computer is protected against the latest threats. Using a firewall will help to protect against malicious software and prevent people from traveling through your network connection. With router security, by using a strong password protection people won't be able to get access to stealing your data and this will improve security. Using a computer network suite such as Norton or McAfee is a good option because they have a variety of software, including anti-virus, firewall, identity protection and back up features. They all work together to protect your computer from threats.

    The Article attached to this link reports commun issues found in hotel internet networks. The author mentions a study conducted with 38 hotels. It resulted that 33 out of the 38 hotels had flaws in their network configuration and allowed the researcher to access unauthorized information via the internet. We all understand that reliable internet connectivity is a priority for guests and business travelers; however, security is a concern that can't be neglected. Another reason to be concerned is that so many softwares and applications are stored via internet. Adding a password is a simple measure that every business should consider. Network issues cold not only hinder guests but the hotel as well.

    Nowadays, since many business travelers connect remotely to continue working while on the road, the potential for theft of corporate information exists. Some hotels still rely on relatively rudimentary hub technology for their networks, and these are particularly subject to hacking. Tested by Ogle, most hotels are lacking of security and responsibility for the safety when guest searching internet. Guests' information is easy for the hackers to steal, which means when we use the network in the hotel, we are almost peeped by other people we are unknown. Such a terrible thing! Hotel should increase its network's security, a hotel could potentially be considered at fault for not taking the necessary precautions to protect their guests from hackers. Based on this article, hotels can use Wi-Fi Protected Access (WPA) encryption, the password can provide kind of base wall to protect security. What is more, it is necessary that having a robust set of firewalls that are managed and properly configured, and educating staff of the importance of security standards.

    According to the research by Cornell University, most US hotels are vulnerable to hackers. There are two main reasons contribute to the issue. One is the flaws in many hotels' network topology, making it possible for customers to lose their privacy. The other is careless employees provide access information to help hackers' breach. Ogle thought that WPA encryption, VPN and training employees are good ways to solve the problems. I think that if the computer networks of hotel are weak, the guests' password, email message or other private information will not be protected, and they will even suffer loss. So it is important for a hotel to use different measures as Ogle recommended to ensure the safety of the computer network.

    this article is talking about the problem on the hotel network security. a author from the Cornell university said he tested wireless network at 38 hotels at the same time. he found that most hotels were easy to break into. moreover, as long as you use the Linux distribution BackTrack and a high-power wireless card and high-gain omnidirectional antenna, you can break into the hotel guest network and then get the password, email message and the website people are viewing. importantly, this procedure just cost 100$. this is full of loopholes. hotel manager should pay more attention on this problem. at the end of the article, the author recommend a security app called Wi-Fi Protected Access encryption. this app require the guest to enter the password if the guest wants to surf the internet.also, he recommend connecting to the internet using a Virtual Private Network (VPN), having updated anti-virus and firewall software and making sure each secured website starts with "https://" rather than "http://".

      The security of guests' connections to the hotels' network seems to be an essential issue in hospitality industry, especially in those commercial hotels. Based on the leaks of the network technology in the hotels, some companies may hire hackers to steal or snoop the secret data of other companies for achieving some business goals during the business people from the victimized companies staying in the hotels. Therefore, if hotels can not make sure their network system can prevent malicious users from intercepting guests' transmissions, they must admit their weaknesses of network technology and warm guests to be cautious when they access the network system of the hotels if they need to view some secret data. Anyway, hotels should keep taking the necessary precautions to protect their guests from malicious users.
  •  
    From what I research from the article, VLAN as a local area network itself actually is quite secure cause the fake IP address means a private one.  And it is already encrypted. But the hackers had imitate the hotel's main server. As for the technology developing, it seems like the more secure the system make, the smarter the hacker would be. 
  •  
    This article introduced how hotels improve their network to enhance security. To reduce the potential for stealing by theft and hacker, the W Dallas Hotel set up virtual local area networks. Compared with relatively rundimentary hub technology and encryption for Wi-Fi, the biggest advantage of this VLANs is to inhibit attackers from using computer to imitate the hotel'smain server. I think increaing a hotel network's security is very necessary, still, people should pay more attention to this and improve the techonology to make sure the security of all aspects.

14 Main Advantages and Disadvantages of Computer Networking - Green Garage - 1 views

  •  
    Advantages will reign from the obvious such as being able to speak in real time to people across the country, therefore communicating messages faster. This helps businesses be more successful due to relaying data faster and more accurately, seeing trends in different areas sooner, to sending files at a quicker rate. Items shared on networks allow for more people to have access to information at a quicker rate along with information being shared more accurate due to being in real time. Time is money and network sharing helps save time which in turn is saving money. Along with saving money because time is being saved, the lack of software changes assists in saving money as well. If you are not having to replace software often, you are able to provide longevity of equipment to help reduce costs. On the other hand there are many disadvantages that can seem to outweigh the advantages if not looking at the entire picture. If a network breaks down, everyone working off of that network can be out of work for the time it is being fixed. Would this be worth taking the risk of calculating how many hours of work that is lost based on how efficiently the system works? Now to fix this issue this requires someone who is trained in this field at a high technical skill level to fix the network error which can cost a great deal of money to maintain.What if an employee is being distracted by the many things the internet has to offer and is using your network to look these things up? They are now being unproductive at work and putting your network at risk for malware, viruses and many other illicit practices. So once again, is the risk worth the reward.
