What are content delivery networks? Discuss some of its uses.
A content delivery network (CDN) is a system of hardware and software that stores user data in many different geographical locations and makes those data available on demand. A CDN provides a specialized type of PaaS but is usually considered in its own category. A news organization could use a CDN to store copies of its news articles. The CDN vendor replicates articles on servers, possibly worldwide, so as to speed response time. In addition to news articles, CDNs are often used to store and deliver content that seldom changes. For example, the company banner on an organization's Web page might be stored on many CDN servers. Various pieces of the Web page could be obtained from different servers on the CDN.

When does it not make sense to use cloud-based hosting infrastructure?
Cloud-based hosting makes sense for most organizations. The only organizations for which it may not make sense are those that are required by law or by industry standard practice to have physical control over their data.

Define enterprise information systems, and describe their characteristics.
Enterprise information systems are information systems that span an organization and support activities in multiple departments. They typically have hundreds to thousands of users. Procedures are formalized and extensively documented; users undergo formal procedure training. The solutions to problems in an enterprise system usually involve more than one department. Because enterprise systems span many departments and involve potentially thousands of users, they are very difficult to change. Changes must be carefully planned, cautiously implemented, and users given considerable training. Sometimes users are given incentives and other inducements to motivate them to change.

The three tier architecture is an arrangement of user computers and servers into 3 categories. The user tier consists of computers, phones, and other devices. The server tier consists of computers that run Web servers and process application programs. The database tier consists of computers that run a DBMS that processes requests to retrieve and store data.
What are the two dimensions of process quality? How can organizations improve process quality? How do information systems improve process quality?
The two dimensions of process quality are efficiency and effectiveness. Process efficiency is a measure of the ratio of process outputs to inputs. Process effectiveness is a measure of how well a process achieves organizational strategy. Organizations can improve the quality (efficiency and/or effectiveness) of a process in one of three ways: - Change the process structure. - Change the process resources. - Change both process structure and resources. Information systems can be used to improve process quality by: - Performing an activity. - Augmenting a human who is performing an activity. - Controlling data quality and process flow
What are traditional database applications?

Explain the relevance of cloud-based hosting today.
Three factors have made cloud-based hosting advantageous today. First, processors, data communication, and data storage are so cheap that they are nearly free. Because data communication is so cheap, getting the data to and from that processor is also nearly free. Second, virtualization technology enables the near instantaneous creation of a new virtual machine. The customer provides (or creates in the cloud) a disk image of the data and programs of the machine it wants to provision. Virtualization software takes it from there. Finally, as stated, Internet-based standards enable cloud-hosting vendors to provide processing capabilities in flexible yet standardized ways.
Discuss wireless LAN and PAN connections.
Wireless LAN connections use the IEEE 802.11 protocol. Several versions of 802.11 exist, and as of 2015, the most current one is IEEE 802.11ac. The current standard, 802.11ac, allows speeds of up to 1.3 Gbps, though few users have an Internet connection fast enough to take full advantage of that speed. Bluetooth is another common wireless protocol used to make PAN connections. It is designed for transmitting data over short distances, replacing cables. Devices, such as wireless mice, keyboards, printers, and headphones, use Bluetooth to connect to desktop computers.
