...1. Volume of Transactions: Volume of transactions is concerning parameter because it can measure and judge the behavior of service provider. For example, when you have two websites, one of them has 100 transactions have been completed, and you have another website with 100,000 transactions have been completed. By comparing these two numbers the costumer will choose the second one with bigger transaction because it is seems more reliable and efficient than the first one. Under volume of transaction parameter come sub parameters, or rules, to organize and clarify the meaning of this number. These rules are: - Period: we should specify a certain period to can judge the behavior of the system fairly. For example, there are two websites, the first one...

...(wheezy) and JVM build 1.8.0, connected via a wireless LAN. To measure energy consumption, we have used Monsoon Power Monitor, a hardware based power profiling tool. Algorithm 1 shows how we experimented with each protocol to assess performance, resource usages and energy efficiency on the client side. We do not measure the energy consumed by the server. First, to warm the JVM, the benchmark application sends small dummy data three times and then sends a randomly generated message to a remote server using different packet lengths ranging from 128 bytes to 1920 bytes. To measure the CPU and Java heap usage, we used jvmTop (github, 2015) and the \proc\[pid]\stat file, respectively. Benchmark procedure for each protocol. 5) What results are presented in support of the major claim? Are there any other interesting minor results? What is your opinion of the paper? Experimental Results...

...1. Lock up the server room Even before we lock the servers, before we even turn them on for the first time, we should ensure that there are good locks on the server room door. The server room is the heart of our physical network, and someone with physical access to the servers, switches, routers, cables and other devices in that room can do enormous damage. 2. Set up surveillance Locking the door to the server room is a good first step, but someone could break in, or someone who has authorized access could misuse that authority. We need a way to know who goes in and out and when. A log book for signing in and out is the most elemental way to accomplish this, but it has a lot of drawbacks. A person with harmful intent is likely to just...

...tabular view for accountants. The third part, the controller, accepts input and converts it to commands for the model or view. Interactions In addition to dividing the application into three kinds of components, the model–view–controller design defines the interactions between them. • A controller can send commands to the model to update the model's state (e.g., editing a document). It can also send commands to its associated view to change the view's presentation of the model (e.g., by scrolling through a document). • A model notifies its associated views and controllers when there has been a change in its state. This notification allows the views to produce updated output, and the controllers to change the available set of commands. In some cases an MVC implementation may instead be 'passive' and other components must poll the model for updates rather than being notified. • A view requests information from the model that it uses to generate an output representation to the user. D) The software implementation layer within the model-view-controller layer. The software implementation layer consists of the Actual Working Code, ActiveRecord, Template View, Transformation View, Data Mapper and REST. ...

...Some scholar praised him for “Calculation, control, and sensitivity” in his work. He was a composer as well as a well-known violinist. He knew that violin can generate complex melody in fast-moving pace, while other instruments, such as harpsichord, and basso continuo hit important bass lines and notes. One of very good example that shows the role of violin and style in the 17th century is Corelli’s Sonata in D major op.5 no.1. Musical style of this work can be described as “free virtuosity”. The performer has to pay attention to how Corelli carefully composed this work in marvelous improvisation. The Baroque violin players were supposed to have sprit of improvisation in their mind and technique in which most modern players...

...1. How response times are affected for the a) Speed of devices In a network, network devices like switch, routers and repeaters will responds to the users based on the speed that ISP is providing and the devices that we are using in a network. To get minimum or agreed responds time we need list down the requirements of customer, order accordingly and user suitable cables like cat5, 5E and 6. So that the components in these network devices will responds accordingly. For example, if it’s a small company with 10 users we don’t need to use high tech servers, printers and other network sharing devices. b) Bandwidth of transmission line Transmission line is a connectivity line through which your network is connected to the internet. These lines are rented by ISP to provide internet. The response times will depend upon bandwidth that ISP is providing. In other words, the amount of downloading...

...FSO: FSO is a line-of-sight (LOS) technology approach. It uses invisible beams of lights to provide optical bandwidth connection. It is capable to send up to 25 Gbps of data including simultaneous voice and video communications. This type of optical connection does not require neither expensive fiber-optic cable nor securing spectrum licenses for radio frequency (RF) solutions. FSO technology is based on connectivity between FSO-based optical wireless units, each consisting of an optical transceiver with a transmitter and a receiver to provide full-duplex capability. Each optical wireless units uses an optical source and a lens or telescope that transmits light through the atmosphere to another lens receiving the information. FSO can provide point-to-point or point-to-multipoint connection with high data rate. It can be implemented on both ring and star architectures, but the best architecture to maximize the availability is to use the meshed architecture that includes both ring and star...

I might also hold the fear that my application may be like something previously designed and possible to buy off a shelf. My greatest fear would be how might the software affect my organization. 2. A business might undertake projects to integrate some of its information systems with its customers' systems in order to provide them with more timely, accurate, and useful information. It might even directly provide applications for its customer's use at low or no cost to the customer. Customers later considering changing suppliers would lose these benefits. Indeed, the very process...
