Q1.Advantages and Disadvantages of adopting server virtualization

Virtualization refers to the separation of a service request from the essential physical delivery of the same service. Virtual memory is used to create more space than the physical memory.

a) Advantages

The deployment of virtual infrastructure by the organization provides an obstruction layer between storage, computing and networking hardware. By using this obstruction technique, it is non-disruptive because the layout remains unchanged once it has been deployed. Virtual infrastructure also helps in managing resources in a pooled manner across the enterprise being used as a single entity (Menasce, 2005). In this way, the Information Technology administrator responds to the dynamic ...

Having different width has been a challenge in web design. This forced many web designers to specify the web browsers that their websites can well be displayed. This is because web pages were designed with fixed measurements. I assume that I am a web designer for a retail store.

- I do agree with Oppenheimer that computers have not lived up to the expectations in education. This is mainly because the use of computer has led to children with hypertext mind. They do not reason concretely as those who learn without the use of the computer. Secondly, the children show a great desire to manipulate physical materials while they are learning through computers. Three, the computers do not give the children the hands on skills that are directly relevant to the employment opportunities and jobs available. The result is that student enroll in technical institutes to learn technical skills ...

The principle purpose of a firewall is to intelligently bar unrequested connections that intend to get into the network. For instance, a user’s laptop connected to an organizations domain can access shared files and folders on the network. However, if the laptop does not have the domain configurations, the firewall bars any incoming connections to the organization’s network from the laptop. Such a feature for the firewall helps to safeguard the network from potential malicious incoming traffic.

Windows Firewall plus other third-party firewalls perform the same principle function of barring unauthorized incoming connections. Third-party firewalls, in the course of their ...
