Technology Hardware and Software Technology

This paper examines contemporary hardware and software trends. Cloud computing is an emerging technology offering computer applications and services that are typically delivered over the Internet on a subscription or pay-per-resource basis. The services are available from data centers that are physically located all over the world, which taken together, are referred to as the "cloud." (The Internet is frequently represented by a cloud in software and networking diagrams.) Clouds may be either public or private. Companies like IBM (Gaultier, 2011) and Microsoft promote the use of private clouds which typically consist of sets of servers run by government agencies or large companies for the exclusive use of their employees (Rosoff, 2011).

Cloud computing allows users to connect to resources running on servers that may be shared or pooled, as opposed to a single dedicated server, as is often the case using the client-server computing model of recent years. Typically each application ran on a specific piece of hardware which, if it was down, required the user to connect to a backup server or suffer an interruption in service (Rosoff, 2011).

Cloud computing brings a more efficient way to access web applications, blurring...

Before cloud computing, companies ran their applications on their own servers, hosted either at the company's own data center or in its own location. This arrangement was fairly labor intensive and expensive, requiring dedicated real estate, IT staff, security and so forth. With cloud computing, businesses are able to move a significant amount of their computing to cloud services providing the same applications previously installed on their own servers. The company's users are then able to access the applications over the Internet (HowToGeek, 2011).
There are several types of cloud computing services available from cloud computing providers. Software as a service (SaaS) provides end-user applications running on pooled hardware resources that are accessed over a network. From the customer's perspective, there is no upfront investment required for either software licensing or servers (Knorr & Gruman, 2011).

Infrastructure as a service, also known as utility computing, is another cloud computing service. IBM, Sun, and others offer virtual servers and storage that an IT department can access on demand. Providers offer various capabilities, including helping IT create virtual datacenters or providing computational capacity as…

The modeling environments was so accurate it could deliver results that aligned at a 95% accuracy rate with the actual results achieved. Another advantage was the use of knowledge management to orchestrate multichannel selling, marketing and service scenarios across the client's specific requirements and needs. The analytics and knowledge management systems were also combined successfully to create a constraint-based engine as well. All of these factors were critical to

Technology in Education For purposes of completing this study of the use of technology in higher education, a local high school was visited, where the technology coordinator provided a demonstration of the learning systems used there. In addition, one senior-level course in Physics was attended where the advance imaging and learning technologies where shown. What was unique about this visit was how easily these technologies can be made to align with

Technology has changed how we teach in the 21st century. Many diverse technologies surface every year, and educators find it difficult learning and integrating all the new technologies their institutions buy or identify. However, appropriate professional development and time to accomplish this is not their only concern. Educators are expected to use all these technologies in all course activities. This desire places much emphasis on technology (the medium) when educators

Software Engineering Requirements Are Volatile: Design, Resource Allocation, and Lifecyles Aren't So Flexible For the majority of software development initiatives, bad requirements are a fact of life. Even when there is a high quality elicitation process, requirement change throughout the software lifecycle model. This is expected, if not desired to build a system that the customers wants and will use. But, it's difficult to change design and resource allocation once these have
