Which of the following is the NIST definition of cloud computing:
"Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models."

Employees need clear and explicit guidelines on expectations for social media engagement. Are they empowered to speak on behalf of the firm? If they do, it is critical that employees transparently disclose this to avoid legal action. Firms may also want to provide guidelines on initiating and conducting dialogue, when to respond online, and how to escalate issues within the organization.

Which one of the following descriptions best identifies the origin of the Internet?
In September, 1969, the ARPANET(Advanced Research Projects Agency Network) was turned on. The first four nodes were at UCLA, Stanford, MIT, and the University of Utah.

Within the context of the Four Ms of effective media engagement, megaphone involves the following:
Outbound communication
The following are examples of digital transformation in the health care sector:

Businesses use social computing to harness the "Wisdom of the Crowds". Wisdom of the crowds is the belief that:____________________
The crowd isn't always right, but in many cases where topics are complex, problems are large, and outcomes are uncertain, a large, diverse group may bring collective insight to problem solving that one smart guy or a professional committee lacks. One technique for leveraging the wisdom of crowds is a prediction market, where a diverse crowd is polled and opinions aggregated to form a forecast of an eventual outcome.

This cloud model is great for organizations concerned about sharing resources on a public cloud. It is implemented on servers owned and maintained by the organization and accessed over the internet or through a private internal network.
In the class lecture, I discuss why cloud computing is important for businesses is that, previously businesses had to store all their data and software on their own servers...some of the problems or disadvantages with this include:
This is not scalable...hard to keep up; hard to budget resources; paying for over capacity that isn't used
