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.

Week 7
Chapter 5: IT Architectures
A computer is an eletronic device operating under the aonctrol of introductions stored in its own memory that can accept, manipulate, and store data.
The lecture considered:
Hardware
Software
Hardware Components: CPU, primary storage, secondary storage, input devise (mouse, keyboards), output deveice (screen,) communication device
Advances in CPU Design
- Complex instruction set computer (CISC)
-Redused instruction (RISC)
Virtualization
Primary stoage: The computers main memory
Random Access Memory (RAM)
- Volatility: Memory is gone when the computer is shut down
- Cache: Memory can stay in the computer when turned off
Random Access Memory (RAM): AMD; IBS, Inte, Sun Microsystems
Read Only Memory (ROM): Flash memory, memory cards and sticks
Computer Categories: Clustering, parallel processing, mosaic browser
Computer categories: Laptops, tablet, PDA's, minicomputers, workstation, desktop, supercomputer, mainframe computer
Software basics - controls how the various technology tool work together along with the application software
- Utility Software
- Application Software
Enterprice arcxhitecture is important for our case study
- Enterprise architecture
- Enterprice architect (information, infrastructure and application architecture)
Backup and Recovery
Bacup is an exact copy of a system's information
Recovery is the ability to get a system up and running in the event of a system crash or failure
Disaster recovery: Ha increased the last years. Financial institutions now spend more then $6 million a year
Web services
APA Style Guide
The basics of the APA style is important for writing the assignment in the right format.
As doing PSOC 6005 this semester I've learned a lot of the basic stuff about headlines, references etc.
