September 1, 2015 HTF 2441 NETWORK The term network is used to define a structure with a characteristic pattern. There are multiple types of networks, such as computer network, electrical network and social network. The computer network appoints the set of interconnected computers and other equipment, to share information, resources and services. It can be divided into different categories according to their scope, their method of connection (cable, optical fiber, radio, microwave, infrared) or its functional relationship (client-server, person to person), among others. The electricity grid, meanwhile, is one formed by electric generators, transformers, transmission lines and distribution lines, which are responsible for bringing electricity to residential customers. The system uses different voltages, where higher are used on longer distances, while tensions are reduced as the power comes close to the user's premises. As for the social network, the concept refers to that structure where different individuals hold different types of relationships. The social network has updated its significance in recent years, since the term began to be used to define Internet sites that promote virtual communities according to interests. MySpace and Facebook are two of these social networks that bring together millions of users who can exchange messages and files with other network members. A network environment can be configured as client-server (c/s) or peer to peer (p/p). A client server environment links a powerfull computer to several, less powerful computers (clients). Clients may access a variety of programs stored o the server and draw upon the server’s processing power to perform tasks more quickely and more efficiently than if they operated in stand alone mode. While classical architecture C / S requires one of the endpoints of communication to act as a server, which can be more difficult to implement the client- Cola -Client enables all nodes to act as simple clients, while the server acts as a tail that is capturing the customer requests ( a process that must pass their requests to another , it does so through a queue , for example , a query to a database , then the second process connects to the database , prepares the request, passes it to the database , etc.). This architecture greatly simplifies software deployment . The P2P architecture originally based on the "Customer -Client -Cola " concept.
Client Server: For example, you want to check your bank account from your computer, a client program in your computer forwards a request to a server program at the bank.

Peer to Peer: For example, Skype.

It also introduce me to key concepts which I have been using in my classes when studying and taking notes. Ironically I found using this method at work as well. Recently I found a solution to an ongoing network problem and my manager approached me asking me to fully research the resolution draft an email and send it out to the entire team.By using the search strategy I was able to gather the correct information that was needed to draft the email and send it to my team. 2)The Boolean operator AND OR NOT stuck in my head the most. I learned that this method is the main component to an effective statement and to broaden or narrow your search. When I use to search google without using the Boolean operator I always wondered why the search engine always gave me along list of searchs that didnt really relate to what I was looking up. By using this method I was able to get the exact results that I wanted and as I mention above this method was also used when I did my initial search statement for the email I sent to my colleagues on how to properly resolve the network issue. 3)Lastly the most important component of a research project is to cite the resources appropiately.

Introduction “Harriet’s Fruit and Chocolate Company was established in 1935 in the Pacific Northwest of the United States to ship gift baskets of locally grown peaches and pears to customers in the United States (Oppenheimer, 2011)” In regards to the physical infrastructure of Harriet’s Fruit and Chocolate Company, my investigation will reveal many important aspects to aid in the planning of the network design. First, I will determine the number of buildings to be used, as well as the distance between them and what equipment they will contain such as wiring closets or computer rooms and the current network devices. Determining the distance will help in the cabling design and wiring as well as the selection of technologies and devices to meet the design goals. My investigation will further reveal any architectural or environmental constraints, such as tall trees within the path that power lines may travel, that will assist in decisions such as whether wireless technologies are feasible as well as if there are any impediments to communications or installation, to include all hazards. Infrastructure architecture consists of the hardware, software, and telecommunications equipment that, when...

...afford to spend and if anyone is technical in the company or are they going to need some outside help to keep up maintenance after the system is in place. (this can add to the cost of the system) My next step would be to start asking some questions about the law firm. I would like to know what the law firm is in charge of doing. Criminal, civil, family or so on; I think this would give me a better understanding of some of the information I may be working with along the way. As a law firm I am sure they spend a lot of time in the courtrooms and in their home offices so other questions I would ask is if they have cell phones and laptops that will need to access information on the network; this will help in a couple of areas, firstly in deciding if we should consider cloud computing or a private network and secondly, how to set up files access and permissions by departments and depending on size of company, maybe servers. Being a law firm a big consideration would have to be security of the information they access and ways of accessing this information. I would like to talk with the employees also, just to get an idea...

...institutions, and a number of private security firms — all working to study and combat data breaches. Analysis With 47,000+ Security incidents analyzed, 621 confirmed data breaches studied, and 19 international contributors, Verizon has ample amounts of data to compile and use to better their network. This data can also be analyzed to see what types of people are making these breaches and what motives they may have for doing so. In the 2013 DBIR, 69% of breaches were spotted by an external party and 76% of the network intrusions were due too weak or stolen passwords. Some of the other factors that have been realized was that 75% of the attacks are opportunistic and 19% of attacks are some form of espionage. There is also much evidence that many of these breaches could be tied to organized crime and gathering financial information. On a very basic level, just looking at the history of organized crime, money has always been in the center in one form or another. The money can be in the form of an exchange for a good or service, or it could be, knowing the financial information of someone for future business proposals or some other malicious intent. Recommendations - Tighter security on the networks. - Since some data breaches are done by resigned employees, instant account closing of all resources to...

...encompass many components that focus on efficient and effective programs, providing services and benefits to the most vulnerable individuals in the state. One of Hawaii’s most profound agencies known in the State of Hawaii that is correlated with human services is “Helping Hands Hawaii.” Although there are many agencies that have different approaches, human services rely on agencies that are most cost-efficient yet effective. Interoperability plays a major role in the future of human services. It is the “ability of two or more systems to exchange information and to use the information that has been exchanged” (Schoech, 2010). The three possible models for approaching interoperability in the human services are Loosely Linked Network Model, Network Model, and Top-Down Model. Human services emphasize in the importance of interoperability, as agencies collaborate with the same identified need to help others. Helping Hands Helping Hands Hawai’i manages numerous programs that benefit the people of Hawaii; this includes Behavioral Health Programs, Ready to Learn, Emergency Assistance Program and many more. Their mission is to support the community by improving the quality of people’s lives through the delivery of goods and services to those who are in need. For families and individuals, Helping Hands Hawaii is a new quality of life that overcomes the obstacles that block the way of meeting their full potential.

Digital Media is a fast growing platform; I didn’t know anything about Digital Media until I started working with a YouTube Network. There are a lot of other online platforms out there such as Netflix, Hulu, Crackle, among others, but Youtube is the largest platform where independent content creators can share their work across the World and monetize their videos. Because YouTube showcases talented people who have channels, Networks started to come around in 2010/2011.
