This can be accessed from a home office computer, a laptop or even through a mobile device, they can simply log onto our website and retrieve information that normal people couldn't. Then through the VPN or virtual private network accessed after establishing a connection to the internet, they can access anything they are given access to under their profile. The data that each employee accesses is on our server and set up through secure networks that make it available only to the certain employee.

Blog Entry 4.1 – IFS H/W Infrastructure

 

In the image above with the use of a keyboard you use input technology and type the data HELLO, the information then travels through the connected system unit. From the Central Processing Unit a Processing Technology interprets the data and translates it into binary codes. As you type on your keyboard it changes to binary data, the ALU and Control Unit use the ASCII code as a means to turn it into binary data and store it in secondary Storage. Theses electrical impulses of on and off data, before being stored is organized into bits and bytes. There are eight bits in a byte. So when you type the message the information is presented on the Output Technology which would be the monitor.

At Ferrum Medical, when a physician logs on to our secure website, they can connect to any pharmacy using our extranet. The physician, being a client uses our server as a proxy between our facility and the pharmacy's server. This client, connects to the internet through a secure firewall to then send and receive sensitive data across a VPN or virtual private network. They after this secure data travels through the VPN it gets verified by the pharamacy's firewall and then get ferried along to its destination, a drug log on the pharmacy server.

Blog Entry 5.1 – Critique Your Competitor’s E-Commerce Website

As Ferrum Medical is a business, and all businesses have assets, so too does Ferrum Medical. We like our competitors have a web page, a way to get information out to our clients and inform them of their options. And like any good business we need an advantage, and to gain it we must see what it is that makes our competitors so profitable. So we must delve into their website and analyze it against the six rules of E Commerce. As one of our competitors we chose Centra Health.

Blog 4.4 - Entity Relationship Diagram























In this Entity Relationship Diagram, there are three main Entities : Customer, Invoice, and Product.
Within each entity there are different attribute types such as Name, but a specific name such as John Smith is an Attribute. Each entity can be described as a table each containing rows and columns, the rows being records and columns being attributes. Each attribute type has its own data type dependent upon the type of information, such as name being text. The customer entity, contains attribute types such as Name, Address, and gender. It also contains a customer key, and ID number that is specific to the individual, such that it can be referred to later. The Product entity contains attribute types such as the type of product, the price and the Product key. Like the customer key it is a reference key used to compare and correlate data in other entites.

Blog 4.3 - Packet Switching Technology

Due to the fact that there are many users online all the time and data is being sent and received simultaneously there needed to be a way in which to send information in a way that computers can understand that can be translated into usable information. Through the TCP many different messages can be sent over the internet via packets in any order that are reassembled later. When computer A wants to share info to computer C in the picture above, the binary data of the message sent from A is broken into manageable packets and delivered to C. This message sent from the computer A,  uses TCP to send its message to computer C using package switching. The IP sets the format for the packet and the location it is to be sent, the IP information tells the router where this location is ad sends it on it s way. These packets travel independently of one another and arrive out of order. Each packet has a header and it contains the destination and sending IP address as well as the order in which things should be arranged.

Blog 4.2 - A Basic Network

  
In the picture above, this is a basic network. Many things happen in the course of a client connecting to the internet depending on which kind of networking system you have connected to your laptop. One way which would be a wireless connection where the laptop uses a transmission medium through an antenna to connect to the internet. The second way would be a physical cable from the computer to an internet router which transfers information from the router to computer.
