53.
Cloud computing refers to a computing environment where software and storage are provided as an Internet
service and accessed with a Web browser. By outsourcing business information systems to the cloud, a
business saves on system design, installation, and maintenance. Employees can access corporate systems
from any Internet-connected computer using a standard Web browser. Some companies, such as Microsoft
and Google, provide free online storage for access from any Internet-connected computer.
54.
Successful implementation of e-commerce requires significant changes to existing business processes and
substantial investment in IS technology. Key infrastructure components include hardware, Web server
software, and e-commerce software. A Web server platform complete with the appropriate software and
sufficient storage capacity and computing power are required.Web server software is needed to perform
fundamental services including security and identification, retrieval and sending of Web pages, Web site
tracking, Web site development, and Web page development. E-commerce software is need to create and
update the product catalog, perform product configuration , shipping cart facilities to track items selected for
purchase, e-commerce transaction processing, and Web traffic data analysis.
55.
The first stage of the problem-solving process is the intelligence stage wherein you identify and define
potential problems or opportunities as well as investigate resource and environmental constraints. During the
design phase, several alternative solutions to the problem are identified and evaluated for their feasibility.
During the choice stage, a course of action is selected. During the implementation stage, the solution is put
into effect. In the monitoring stage, the decision makers evaluate the implementation to determine whether
the anticipated results were achieved and to modify the process in light of new information.
56.
Expert systems consist of hardware and software that stores knowledge and makes inferences, similar to those
of a human expert. Robotics involves developing mechanical or computer devices that can paint cars, make
precision welds, and perform other tasks that require a high degree of precision or that are tedious or
hazardous for humans. Vision systems include hardware and software that permit computers to capture, store,
and manipulate visual images. Natural language processing also a computer to understand and react to
statements and commands made in a natural language. Learning systems are a combination of software and
hardware that allows a computer to change how it functions or reacts to situations based on feedback that it
receives. A neural network is a computer system that can act like or simulate the functioning of the human
brain.
