...Dedicated and Shared Servers are 2 of the most widely used servers for web hosting purposes. With dedicated server hosting, the web-users would locate every file and data that he owns on the server, utilizing all the resources on the server. Dedicated server is suitable for the case of companies with huge websites, which are loaded with hundreds of pages and links, pictures and images, require for a faster load time for each of their web page because of the huge number of visitors anticipated to be accessing their website with thousands of them trying to load a particular web page all at the same time. Dedicated server hosting provide the exclusive right to the one and only website residing and utilizing its dedicated server. For any companies with a smaller websites and limited number of visitors, choosing for a shared server would be a better choice because the cost of a shared hosting server is at least 20% to 40% lower than a dedicated hosting server, which would help to save up some significant amount of money for some other stuffs whilst at the same time, they are good and comfortable with the shared hosting server which is shared between many other websites on the same server utilizing the same bucket of resources. The key differences between these 2 types of hosting servers are: 1.

...Virtual private server (VPS) is fashioned on similar lines as a dedicated server is but in a shared environment. A large physical server is sliced out into smaller virtual portions and leased to different customers. It is similar to shared hosting as many customers share one large server. It is similar to dedicated hosting in the sense that each customer hosting on these virtual portions enjoy the same features as what a dedicated hosting customer gets. VPS server hosting comes at a much lesser cost than a dedicated server and offers more features, privacy and control than a shared server. Startups and small businesses that are looking for growth in the near future prefer the VPS server to launch their websites. The VPS hosting is available in the two options of managed and unmanaged VPS services. Fully Managed server hosting:...

...The Printer Capacity Problem You are designing a manufacturing system at a Greenfield site for a family of printers. You currently offer 8 printers whose annual demand is uncorrelated and forecasted as normally distributed with parameters as given in the table below (units are in ‘000). The manufacturing system will entail a system of parallel lines. Each line will assemble and test printers. Each line can be dedicated to a printer type or can have some amount of flexibility. That is, a line can be designed to assemble and test any subset of the printer types. Assume each line will have dedicated capacity of 100,000 units per year, regardless of whether it is dedicated or flexible. The annualized cost of building and operating a dedicated line for any printer type is estimated to be $ 1,200,000. Suppose that annualized cost building and operating a flexible line is the cost of a dedicated line, $1,200,000, plus an estimate of $120,000 to $150,000 for each additional product that the line can make. Thus a line that can assemble printers A, F and G will cost between $ 1,400,000 and $ 1,500,000 annually. The unit contribution margin of each printer is $25, that is, the difference between revenue and the cost of material and distribution. Use Flexcap (Software on G Drive) to find a good capacity strategy for this facility. Printer Type |A |B |C |D |E |F |G |H | |Mean annual Demand |80 |80 |60 |60 |40 |40 |20 |20 | |Std deviation of annual demand |10 |30 |10 |30...

...are difficult to access throughout the company. The addition of server solutions will negate this issue and provide access to all of this information throughout the company and provide access to all sales agents in the field. Maintaining the customer base and expanding upon that base are vital to the success of the company and will require solutions that limit system access to only authorized personnel and devices. Having sales agents in different areas of the world and constantly traveling will require that they have mobility and flexibility to access the information that will ensure they are able to perform their duties. A server system will be installed to monitor mobile access to the network and VPN. The home office will be the site for all of the servers and network abilities to ensure one central location to the information provided by the company. The sales and marketing department will have one server dedicated to it for their information. This will physically remain in the IT department but will be logically placed in the Sales and Marketing Department.

...How to Enhance the Performance of VPS Server? VPS is a combination of shared hosting and dedicated server that provides user an exceptional mixture of features with affordability. VPS assures high-performance, durability and reliability; however, it would be unfair to remain highly dependent on your server and let it go as long as it can. As your business continues to grow, the pressure and load on the equipment goes upward as well. To maintain server efficiency, consider finding out some practical approaches to configure its conduct. For escalating the performance level, below are some measures that companies can apply to improve load times and response rates, in order to achieve better outcome. 1. Installing caching software Caching is one of the easiest way to boost efficiency as it stores temporary files on your hard drive that offers repeated access to the website at a great speed. Requesting files repeatedly will result in slow performance, but temporary file storage on RAM improves latency and website speed as it provides access to frequently accessed web data quickly that lets your customers land on your website within a short period. Installing caching software such as Memcached, Varnish, and Squid will help speed your website significantly. 2....

This type of transfer rate would definitely clear up congestion on the network, so there would not be issues in the morning when everyone is online doing attendance and checking emails. Even with the 23 other classrooms added to the network which will solve the principles issues with the slow network and the connection of all the classrooms. This type of bandwidth would make John happy because he is a HVAC Technician, and this will be usefull fort the remote access to his devices from home. This solution should make it easier for network accessories and peripherals such as printers and print servers. By working with such cabling with a built in CSMA/CD (Carrier Sense Multiple Access with Collision Detection) contention-based media access control technique, help address and solve the problem of collisions. To continue on, by assigning each network interface card (NIC) on each personal computer, it will minimize collisions to a number that users will not even see. Seeing that the school is growing, that means that the network is growing also. With this growing network I would make the backbone fiber optic. This allows room for adding voice over IP (VoIP) to network services and overrides the problem of congestion when the new area backbone is turned on which will assist Alfred Wingfield problems concerning the VoIP and the backbone...
