Instructions: This assignment must be done in APA format. A minimum word count for the overall assignment is 1600 words (not including reference portion). A minimum requirement of 4-6 references (with in-text citations) is required. Although this assignment is APA format, it must keep the answer and question format. See details below.
Format for Assignment:
Instructor Notes:In professional writing avoid using first person “I” and third person “we”, as they detract from the quality and turn professional researched statements into opinions. Instead of “I” use, for example, use “the writer, the author or the researcher”.
Instructors General Note:
- Beyond examples and names, give two examples of application of the data. Who uses it? What does it tell you? How are the data applied?
- Beyond what is it, how is it applied? Why
- Beyond naming them, discuss the pros and cons for each. Give examples from the research where these were breached. Why? Who? Consequences?
- Beyond describing the differences explain how each are used in quality improvement.
- Please answer these as four, numbered answers
- What are data elements? Give two examples of a data element.
- What is HL7?
- Name two ways discussed in this chapter for sending information securely over the Internet.
- Describe the difference between a data element and a data set.

Instructions: Write an 150 word response to each post. A minimum of one (1) reference is to be used (with in-text citatation). Be sure to wrote as of your talking to the person. Please be detailed as possible.
- Computer networks play a dominant role in transmitting data within a large corporation and with smaller companies. A network is simply a set of computers (or terminals) interconnected by transmission paths. These paths usually take the form of telephone lines; however, as technology has advanced, other media, such as wireless and infrared transmission have replaced older technology to send data. A network serves one purpose: exchange stored data between multiple users, computers, and other devices (Qureshi & Hartman, 1997).
Companies either have a local area network (LAN) or a wide area network (WAN) system that allows different users the ability to exchange data in real time. These networks are used depending on the size and location of these users. A LAN network would be used by a company that may have several users in a close geographical location or the same building. These types of situations would be all the computers and terminals in a small hospital or physician’s office needing to communicate within that area. These users transmit the data short distances through ethernet cables owned by the company. These networks can be faster to run, cheaper to maintain, and more reliable than WAN networks (Sharp, 1998).
A WAN would be used for companies that have multiple offices or users over a larger geographical location like nationwide or international users. This type of network would be needed by a large hospital system that have different locations in a region. Wide Area Networks are comprised of more than one LAN in order to connect the multiple users together. WANs can be set up through internet service providers like AT&T or Xfinity for their networking needs. These types of networks can be slower due to multiple issues like upload and download speeds being affected by how busy the server is (Gartee, 2011). These networks normally cost more than LAN’s due to the quality of service the company is requesting. This would hit the financial bottom line more than running their own Ethernet cables for transmitting data.
- There are some similarities between LAN and WAN but there are some distinct differences that set them apart. Lan (local area netwrok) is a group of computers that are connected together and are usually in the same building with all the computers on the same server. Devices on a LAN often use the LAN’s infrastructure to connect to the public internet, but they can often communicate with each other directly through the LAN quicker than a WAN network (WAN &Prokopchina, 2014). This can be ideal for companies that need to send and receive information quickly. (WAN &Prokopchina, 2014). With a LAN, the server is usually under the control of one administrator who can allow or deny access into the network. One of the main advantages of the LAN are the speed at which data is transferred while a downside is the small area that is covered by the LAN (Fiho&Galvao, 1998).
The WAN network (wide area network) is by name, covers a wide geographical location and can cover a much wider range than a LAN. The WAN can be contained to one building over accessible to the public. WANs are majority too complex to be managed by private administrators, and for that reason, they usually have a public ownership. The main advantage to the WAN is the large area that is covered but with the large area and access by the public, firewalls and other security measures are needed.
