Conversely, there are separate dedicated servers and clients in a client-server network. While client workstations usually can access the same files that are stored on the server, the server has the ability to determine which users can and cannot. One more thing to consider when looking at the differences of the two is cost. Peer-to-peer networks are less expensive but offer almost no security. Client-server networks normally have millions of users and offer elaborate security measures so the price can be significantly higher.
Essay Comparing Microsoft and VMware solutions for virtual computing Reading many different articles from websites comparing the two virtualization platforms that Microsoft and VMware has put out for use. Microsoft has Hyper-V Windows server 2012 R2 + System Center 2012 R2 and VM ware has Vsphers 5.5 Enterprise Plus + vCenter Server 5.5. By looking at the comparison side by side, it looks as Microsoft offers a lot more services and has doubled more things that what VMware offers. One example is Microsoft lets you use many of its services without additional licensing fees. Microsoft offers 2 physical CPUs per license where VM only offers one per CPU.
Again, the capacity range varies for some people have built 40 TB machines and some only have 2TB. With port replication and add-on hard drive controller cards there is hardly a limit on size. As far as fault tolerance, raid 50 is fairly stable if set up correctly, raid 10 is thought to be one of the best setups since more drives can fail at one time without data loss. NAS can be used for sharing files among multiple users / computers. It can also act as an external backup device if needed, thus by using a NAS you can easily get additional or extra storage for all your networked computers which can be quite cost effective in the long run and many NAS devices allow you to add additional space for more storage (Kumar) Now days there are so many different devices being used in our homes from all sorts of mobile devices to a range of gaming devices.
Through the use of logical organization and segmentation an OS and computer hardware can effectively deal with user programs and data in the form of modules, gaining a number of advantages when it comes to memory management requirements (Stallings, 2012). Last we will take a look at physical organization. When dealing with memory we know that there are two types: main and secondary. Main memory gives a user fast access but comes at a high cost and volatility; secondary memory on the other hand is slower but cheaper and much more stable. In this two-level scheme, the way in which information flows back and forth is a major system concern (Stallings, 2012).
Why would people utilize it if it’s so costly? RAID 1 is the most expensive because its disk overhead requires all of its drives to be running. Its 100% redundancy means that no data will be lost. 6. If you, as a home computer user, were to purchase a form of RAID, which would you choose and why?
Advantage: - save cost of bandwidth - Better outage protection and security– colocation provider will manage and maintain the server. - Each party owns the server software and machinery. Each party can upgrade the server and install software or tools whenever they want. Disadvantages: - Colocation providers can be hard to find. Most providers locates in large cities with major network hubs, if a small business doesn’t locate there, it won’t find many colocation options.
The current fastest USB technology is called USB 3.0. Advantages: * Extremely common form of connectivity * Can ‘daisy chain’ up to 127 different devices together at one time * Since the release of USB 2.0, users are now able to perform backups through USB external HDD’s and other forms of USB media. This technology sparked new advancements with devices such as USB flash drives, and other external storage devices. Disadvantages: * While you can connect to 127 different devices through one USB port, the bandwidth between the devices is shared which means that the more devices sharing the connection, the slower they will be. * Some devices that might seem to benefit users by being bus powered devices receive their power through the USB connection which can also reduce power and efficiency of the computer and devices in use.
Search engines are the driving source for online shopping. When consumers can type in a name of a product and click search hundreds of stores come up with pricing of the product. People like choices, and would rather search through the web for the best product and pricing. Associability plays key role in the success of companies. Companies have to pay a huge price to have their store front at the top of the search list.
The housing of all departments in one location offers both an advantage and disadvantage, but I would have to say that the disadvantage outweighs the advantage. The housing of all departments in one location brings down the profit margin and causes them to see a lesser profit. Since the competitors aren’t housing all departments in the same location they will see a larger profit. This also means that Albatross Anchor is unable to reduce their costs. An economy of scale is the reduction in long-run average and marginal costs arising from an increase in size of an operating unit.
This is not only about management, but more sort of a way to eliminate costs, that are not essential for production process. Most businesses that manufacture their product spend most time on inspecting quality and repairing faulty products, which aims to eliminate errors from manufacturing process, in this simple method. Greatest benefit of JIT is that business reduces operating cost, and therefore has advantage over its competitors. There is also a benefit of reducing manufacturing times and shortening delivery
