Networks, Telecommunications, and Wireless Computing
Telecommunication systems enable transmission of data over public or private networks. A network is a communications, data exchange, and resource-sharing system created by linking two or more computers and establishing standards, or protocols, sp that they can work together.
Network basics: LAN – MAN – WAN
Networks are differentiated by: Architecture, topology, protocols and the media.
An IP address can find where that exactly computer is working from. Companies can use this tool to see where to advertise and where the target customers are. One example is Google which can find where people are searching for different products, and how many IP addresses that use Google.
Client/Server networks
A client: A computer designed to request information from a server
A server: A computer that is dedicated to providing information in response to an external request,
A client/server network: A model for application.
Media
Network transmission media refers to all the various types of media that is used to communicate between computers.
Wire Media can be used as physical paths to carry electrical signals. This is a good tool for people working outside their office and can connect to the Internet from different places.
E-business networks consist of virtual private network (VPN) such as the HPU Pipeline and value added networks (VAN.)
The wireless technology makes people work 24/7. It gives users a life connection via satellite or radio transmitters. This type of technology is growing. Bluetooth is convenient in creating a niche market for traditionally cabled devices. Radio Satellites is not as reliable as satellite, including wireless connections. Satellite connections can easily be broken compared to cables.
In the second part of the class we watched three videos considering RFID. RFID use active tags in the form of chips or smart labels that can store unique identifiers and relay this information to electronic readers. This is a decent tool for use in supply chain management for the product to go from production to the warehouse for thereafter to the retailer. We discussed in class the positive and negative effects of RFID.

Week 9
Chapter 6 - Databases and Data Warehouses
The group, The Bugs had at a discussion considering information cleasning and scrubbing. To increase the quality of organizational information and also the effectiveness of decision making, business must formulate a strategy to keep information clean. This is the concept of information cleansing and scrubbing, a process that weeds out and fixex or discards inconsistent, incorrect, or incompete information.
Harrah's Entertainment, Inc. is the world's largest provider of branded casino entertainment through operating subsidiaries. Since its beginning in Reno, Nevada 70 years ago, Harrah's has grown through development of new properties, expansions and acquisitions, and now owns or manages casino resorts on four continents. Information cleansing and scrubbing is therefore necesssary to keep te right information about its customer and be loyal to them. The Bugs first discussed this question before discussing other groups' questions.
What might occur if Harrah's fails to clean or scrub its information before loading it into its data warehouse?
- Information sent to wrong or non-existing address.
- Double entries could cause an customer to not get the benefits he/she is supposed to get, or cause the information to be inaccurate.
- A Diamond loyalty level customer which due to double registration is treated like the typical average customer.
- If a customer moves, but the address has not been registered correctly, information will be sent to wrong people.
- Not being able to create individualized marketing programs for each customer: then customer loyalty will decrease.- Decrease in customer visits
- Customers might not get the actual value of the Total Rewards program if they are registered more than once in the database.

Week 8
Mid term
For the final exam I would recommend to have a home exam. This is because I learn more of studying the topics and do research if I don't find the answer instead of having time pressure in class.

Group presentations
T.A.S.K: Security Information Alpha Team: Eyes Everywhere Lucky #7: Information Security and great Granola Inc. A company has to consider these criteria when going online: Insiders, hackers, social engineering, dumpster diving, viruses, identify thefts, phising, elevation of privilege, hoaxes, spyware, spoofing, sniffer, package tampering Hot Chocolate: Thinking Like the Enemy - People and technology are the two primary lines of security defence Yankees: Stealing SoftwareOur Group, the Bugs: Ethical issues in the working place. One must always talk to the people involved when it comes to ethical issues.
Ethics
Considering ethics in the working place always have to deal with human beings. Ethics are the principles and standards that guide out behavior towards other people. Information ethics considers how individual determine to use information and how information affects them.
All organizations should build a corporate culture based on ethical principles that employees can understand and implement. Furthermore, ePolicies should also be addressed as new technology is easy to abuse. An ethical computer use policy contains general principles to guide user behavior. e-mail privacy policy details the extent to which e-mail messages may be read by others. There is a need for managers to create a corporate culture based on trust. Moreover, the best path for an organization planning to engage in employee monitoring is open communication about the issue.
When an organization has considered the First Line of Defence: The people it can start to consider the Second Line of Defence: The technology.

Week 5
This Tuesday the Norwegian Counselor came to visit HPU, meaning that we had to be away for an hour. However, we presented The Bugs group presentation about e-Groceries and how they can improve to become user friendly on the Internet. One always need a nice web site which is easy for the user to navigate on. Furthermore, one must advertise on search engines, other web sites and/or optimilize their web page for the user to find it. It doesn't help to have a nice web site if nobody can find it.
Ethics
Ethics is important in every organization as it considers human being. Ethics and security are two fundamantal building block for organizatins.
HTML - Creating a Web Site
We learned the basic details on how to create a web site using HTML codes.

Week 4
Presentations
As usual the class started with group presentations about strategic decision making. Our group The Bugs presented “Discovering Reengineering Opportunities.” I found that interesting as it is an opportunity for a company to increase efficiency. We looked at how HPU Online registration can be improved and found that there are broken, redundant and antiquated situations that can be improved such as class such, current use of advisors and holds. Furthermore we saw that the tuition payment can be improved by reengineering.
E-business
The next part of the class was a lecture about e-business. I find that a very interesting and important topic today as the world get more and more dependent on new technology. E-business makes it easier and more convenient for people to communicate and work across borders.
E-business is the conducting of business on the Internet, not only buying and selling, but also serving customers and collaborating with business partners. The history of technology consists of disruptive and sustaining technology. With disruptive means new technology that destroys other products. iPod is an example that destroys the walk-man, disc-man etc. Sustainable technology on the other side makes better and improving products such as faster cars.
The evolution of the Internet has had an enormous impact on the communication between people, companies and countries.
WWW: a global hypertext system that uses the Internet as its transport mechanism.
Http: The internet standard that supports the exchange information on the www.
Intranet: Internalized portion of the Intranet used for information inside a company and is protected from the outside
Extranet; An intranet that is available to strategic alliances
Portal: A Web site that offers broad array of recourses and services like e-mails, discussion groups, search engines etc.
Kiosk: A publicityaccessible computer system that has been set up tp allow interactive information browsing.
E-business models
An e-business model is an approach to conducting electronic business on the Internet.
B2B: Business to business
B2C: Business to consumer
C2B: Consumer to business
C2C: Consumer to consumer
A business on the Internet includes benefits and challenges. Organizations must refocus their information systems and ways of working. People must be thought to use the new equipment in order for the organizational change to happen. Furthermore, having a service online demands good customer service. People do not trust the Internet as face to face conversations and the customer service must always be available. Moreover the web page must be user friendly and easy to find. Search engines such as Google are one way to make the web page visible.
Marketing on the Internet is one way to make the web page available.
On line ads, pop-up ads and assosiates programs are some ways the marketing departments of an online organization should consider. Moreover to search engine optimilization of the web page and pay per click advertisements on Googe are other ways of making the web available for potensial customers. As been working for a Norwegian search enigne for 3 and a halv years, I've learnd that it doesn't help to have an attractive web site if nobody finds it.
