What factors made Netflix (or internet pure plays) so disruptive & profitable? How does the long tail create competitive advantage for Netflix (and other digital companies)? What caused the rise and fall and rise again of Netflix?

1. Analysts and managers have struggled to realize that dot-com start-up Netflix could actually create sustainable competitive advantage, beating back challenges from Wal-Mart and Blockbuster, among others. Data disclosure required by public companies may have attracted these larger rivals to the firm's market. 2. Netflix operates via a DVD subscription and video-streaming model. These started as a single subscription, but are now viewed as two separate services. Although sometimes referred to as "rental," the model is really a substitute good for conventional use-based media rental. 3. Fear of clinging to a sure-to-shrink DVD-by-mail business model prompted Netflix management to split and reprice its services. However, the price increase, a poorly handled rebranding effort, and a process that would have made the firm's services more difficult to use all contributed to the firm's first major customer contraction and satisfaction decrease.

What are the three reasons (aka three tactical advantages) we use a database? What is the strategic value of having a database?

1. Preserve data integrity - assurance that data is consistent, correct, and accessible 2.Eliminate data redundancy -unnecessary repetition of data that slows data processing 3.Limit data view (query, report) so that users only see what they need to see, as cleanly and clearly as possible Benefit of a DBMS over Excel: Need for Less Storage =means you spend less $$ Less redundancy = Less searching, confusion, and rework Also... A firm's database management system can be set up to work with several applications both within and outside the firm. 1 database = increased valued chain efficiency = more saved $$ Connects activities across the value chain!

What happens when you enter an address into your web browser

1. web address convererd into IP address 1.1 IP address goes to DNS server from tehre 2. IP address asks Root Name Server do you know the address "x" 3. if no then IP address goes back to DNS server and then back out 4. IP address asks .com Name Server 5. Nope... 6. IP address asks x.com name server 7. Yep...sends "x" IP address back to the DNS server and then back to the user's computer to display the file on their computer browser

What is the internet? What were major contributions to its creation in the 1960's, 70's, 80's, and 90's?

60s: Dwight Eisenhower - military background - need science research and military Bob Taylor - Typed in 3 words - first computer broke 70s: made a "desktop computer" - Alto (what jobs looked at) scientists need to share research among university campuses Falling of the berlin wall- talking to countries we haven't connected to in a long time 90s What protocol invented in 90's is the basis for WWW? HTTP = HyperText Transfer Protocol Watch the video from the internet day - its the history of the internet and add to doc 'history of the internet' https://meeting.austin.utexas.edu/p29j0op734i/?launcher=false&fcsContent=true&pbMode=normal

Domain name service (DNS)

A DNS server is used to convert that name to an IP address Domain Name Service is the Internet directory service that allows devices and services to be named and discoverable. It helps your browser locate the appropriate IP address for the web address entered DNS works like a hierarchical set of phone books managmed by 13 root name servers in the world

Why is user concerns about privacy a risk to Facebook?

Beacon failed because it was an opt-out system that was not thoroughly tested beforehand and because user behavior, expectations, and system procedures were not completely taken into account. Usefacebook login for other sites login needs like myedu: These efforts come with risks, including enabling free riders that might exploit the firm's content without compensation, and the potential for privacy and security risks.

Cloud Computing/Why would one use SaaS (rent) vs Packaged ERP (buy) vs Customized ERP (build)?

ERP = Packaged, On-Premise; More expensive to start-up bc of all the fornt end costs; costly to support it due to IT staffers, replacing hardware, maintainance calls and upgrades; its very customizable;less secure - you have control of your data but since cloud software is looked at by more IT people might be more secure bc bugs will be detacted faster if it has a vast client base. Anohter ERP = Hosted, On-Demand Look at tutle's chart

How does the online ad business model work and how does it make money?

Google ads are keyword advertising, meaning they're targeted based on the words in a user's search query. Advertisers bid on the keywords and phrases that they'd like to use to trigger the display of their ad. Linking ads to search was a brilliant move, since the user's search term indicates an overt interest in a given topic. Want to sell hotel stays in Tahiti? Link your ads to the search term "Tahiti Vacation." To determine Page Rank Google looks at.. Quality of the site, ads, links to your site, what else does google look at? Concise descriptions that pop up with the google search URL

What network strategies is Google using to increase network effects?

Google's explanation for its large share of the Internet search market — more than 60 percent — is simply that it is a finely honed learning machine.

HTTP

HTTP or hypertext transfer protocol, is a set of rules allowing web browsers and web servers to communicate A protocol is a set rules for communication The methods of communicating online was varied and scattered in 70-80's: We needed an "Internet Protocol". (Shorten to "IP")

Hypertext Transfer Protocol (HTTP) Hypertext markup language (HTML)

HTTP: allows networks to talk - regardless of where website hosted I can have access The http:// you see at the start of most Web addresses stands for hypertext transfer protocol. A protocol is a set of rules for communication—sort of like grammar and vocabulary in a language like English. The http protocol defines how Web browser and Web servers communicate and is designed to be independent from the computer's hardware and operating system. It doesn't matter if messages come from a PC, a Mac, a huge mainframe, or a pocket-sized smartphone; if HTML = Hyper Text Markup Language that is the code behind a webpage Most Web pages end in ".html," indicating they are in hypertext markup language. While http helps browsers and servers communicate, html is the language used to create and format (render) Web pages.

How has U.S. Advertising Spend changed since 2006? Explain what consumer habits, tracking, and targeting have to do with this.

Internet advertising major media ad category to show significant growth. There are three factors driving online ad growth trends: (1) increased user time online, (2) improved measurement and accountability, (3) targeting. Measurement metrics can be linked to payment schemes, improving return on investment (ROI) and accountability compared to many types of conventional advertising.

How do the technologies of the Internet combine to answer the questions: What are you looking for? Where is it? How do we get there?

Internet then your computer needs to know the answer to three questions: 1. 1. What are you looking for? 2. Where is it? 3. And how do we get there? the URL displayed really says, "Use the Web (http://) to find a host server named 'www' in the 'nytimes.com' network, look in the 'tech' directory, and access the 'index.html' file."' o There are lots of "www" hosts o Nytimes.com = network o Lookin in the "tech" folder of the "nytimes.com network o Access the file 'index.html' file Think of the domain name as the name of the network you're trying to connect to, and think of the host as the computer you're looking for on that network.

Neutral supporters - Netflix - bc want all proiders to evenly suppor their company Neutral opponents - compcast they want to encourage larger control of the market

Long Tail

Netflix can offere more movies than a block buster due to size so gets the sale on the movies that blockbuster wont house bc they aren't high turn over rate (and Blockbuster doesn't have room for anyting but high turnover movies since has to make sacrafices with limited space) Netflix - ship unpopular titles Rapsodiy iTunes Amaxon - most books sent aren't sold at boarders Geographic constraints go away with netflix model and untapped market open longtail makes more money bc more movies overall means you are bound to please more audiences and have more sales due to the size of your audience

How is the pricing of Google different than the traditional model of ad pricing? How does this effect risk sharing for the advertiser?

Not only are search ads highly targeted, advertisers only pay for results. Text ads appearing on Google search pages are billed on a pay-per-click (PPC) basis, meaning that advertisers don't spend a penny unless someone actually clicks on their ad. If no one clicks on an ad, Google doesn't make money, advertisers don't attract customers, and searchers aren't seeing ads they're interested in. Google ad ranking formula rewards top performing ads by considering two metrics: Ad Rank = Maximum CPC × Quality Score Create high quality ads and your advertisements might appear ahead of competition, even if your competitors bid more than you. But if ads perform poorly they'll fall in rankings or even drop from display consideration. When an ad is clicked, advertisers don't actually pay their maximum CPC; Google discounts ads to just one cent more than the minimum necessary to maintain an ad's position on the page. So if you bid one dollar per click, but the ad ranked below you bids ninety cents, you'll pay just ninety-one cents if the ad is clicked.

Why did many analysts incorrectly suspect that Netflix was doomed to fail? Why is branding and customer happiness particularly important for online (aka internet pure play) firms?

for examples of 1.0 and 2.0 look at slides 1.0 one way 2.0 interactive API encourages developers to flock to it API was very open Facebook's platform allows the firm to further leverage the network effect. Developers creating applications create complementary benefits that have the potential to add value to Facebook beyond what the firm itself provides to its users.

Net Neutality/ Modem

modem (modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information and demodulates the signal to decode the transmitted information (ex so you can hear what the original message of the person on the other line of a phone reciever) The most familiar type is a voice band modem that turns the digital data of a computer into modulated electrical signals in the voice frequency range of a telephone channel. These signals can be transmitted over telephone lines and demodulated by another modem at the receiver side to recover the digital data.

Why is the benefit of signal transfer that is fault tolerant and how do analog and digital differ on this?

signal transfer that uses multiplexing that is fault tolerant means that if the message has mutliple routes to get to the the "goal", it also means you can shove more messages through a single channel and this saves money bc one channel doesn't have to be reserved for a single A to B connection. With analogue or sound waves you can only have one channel bc sound waves can't be broken up into bits. Thus analogue networks are both suspetible to roadblocks of communication, and more expensive to build bc more equitment is needed if each channel can only transfer a message from point A to point B

Net Neutrality/ Local area network (LAN) Net Neutrality/ Wide Area Network (WAN)

A local area network (LAN) is a computer network that interconnects computers within a limited area such as a home, school, computer laboratory, or office building using network media.[1] The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines.[c

Server farm (aka Data Center)

A massive network of computer servers running software to coordinate their collective use. Server farms provide the infrastructure backbone to SaaS and hardware cloud efforts, as well as many large-scale Internet services.

Service level agreement (SLA)

A service-level agreement (SLA) is a part of a service contract[disambiguation needed] where a service is formally defined. In practice, the term SLA is sometimes used to refer to the contracted delivery time (of the service or performance). As an example, Internet service providers and telcos will commonly include service level agreements within the terms of their contracts with customers to define the level(s) of service being sold in plain language terms.

Record

A single instance of whatever the table keeps track of

Basic Database Terms Where do we see signs of primary keys and databases in our daily lives running the world?

A table or file refers to a list of data. A database is either a single table or a collection of related tables. The course registration database above depicts five tables. A column or field defines the data that a table can hold. The "Students" table above shows columns for STUDENT_ID, FIRST_NAME, LAST_NAME, CAMPU.S._ADDR (the "...". A row or record represents a single instance of whatever the table keeps track of. In the example above, each row of the "Students" table represents a student, each row of the "Enrollment" table represents the enrollment of a student in a particular course, and each row of the "Course List" represents a given section of each course offered by the University. A key is the field used to relate tables in a database. Look at how the STUDENT_ID key is used above. There is one unique STUDENT_ID for each student, but the STUDENT_ID may appear many times in the "Enrollment" table, indicating that each student may be enrolled in many classes. The "1" and "M" in the diagram above indicate the one to many relationships among the keys in these tables. Look at the table here http://2012books.lardbucket.org/books/getting-the-most-out-of-information-systems-v1.4/s15-02-data-information-and-knowledge.html

Cookies

But perhaps the greatest degree of personalization and targeting comes from cookies. Visit a Web site for the first time, and in most cases, a dialogue between server and browser takes place that goes something like this: Server: Have I seen you before? Browser: No. take this unique string of numbers and letters (called a cookie). I'll use it to recognize you from now on. The cookie is just a line of identifying text assigned and retrieved by a given Web server and stored on your computer by your browser. Upon accepting this cookie your browser has been tagged, like an animal. As you surf around the firm's Web site, that cookie can be used to build a profile associated with your activities. If you're on a portal like Yahoo! you might type in your zip code, enter stocks that you'd like to track, and identify the sports teams you'd like to see scores for. The next time you return to the Web site, your browser responds to the server's "Have I see you before?" question with the equivalent of "Yes, you know me;," and it presents the cookie that the site gave you earlier. The site can then match this cookie against your browsing profile, showing you the weather, stock quotes, sports scores, and other info that it thinks you're interested in. Cookies are used for lots of purposes. Retail Web sites like Amazon use cookies to pay attention to what you've shopped for and bought, tailoring Web sites to display products that the firm suspects you'll be most interested in. Sites also use cookies to keep track of what you put in an online "shopping cart," so if you quit browsing before making a purchase, these items will reappear the next time you visit. And many Web sites also use cookies as part of a "remember me" feature, storing user IDs and passwords. Beware this last one! If you check the "remember me" box on a public Web browser, the next person who uses that browser is potentially using your cookie, and can log in as you!

What do cloud computer do to switching cost and access to high-powered computer?

By lowering cost to access powerful information systems, this lowers switching costs. esp attractive for start-ups

Cloud Computing/What is cloud computing and the different categories of it?

Categories: hardware clouds sometimes a firm develops its own custom software but wants to pay someone else to run it for them. That's where hardware clouds, utility computing, and related technologies come in. In this model, a firm replaces computing hardware that it might otherwise run on-site with a service provided by a third party online. PaaS:Platform as a service Where cloud providers offer services that include the hardware, operating system, tools, and hosting (i.e., the platform) that its customers use to build their own applications on the provider's infrastructure. In this scenario the cloud firm usually manages the platform (hosting, hardware, and supporting software), while the client has control over the creation and deployment of their appliation. IaaS: infrastructure as a service (IaaS). This is a good alternative for firms that want even more control. In IaaS, clients can select their own operating systems, development environments, underlying applications like databases, or other software packages (i.e., clients, and not cloud vendors, get to pick the platform), while the cloud firm usually manages the infrastructure (providing hardware and networking). Ex. Amazon, Rackspace, Oracle, Dell, HP, and IBM.

Cloud Computing/What are the business models, benefits, and risks for companies PROVIDING SaaS?

Cloud computing is affecting the competitive dynamics of the hardware, software, and consulting industries. In the past, firms seeking to increase computing capacity invested heavily in expensive, high margin server hardware, creating a huge market for computer manufacturers. But now hardware firms find these markets may be threatened by the cloud. Cloud computing can accelerate innovation and therefore changes the desired skills mix and job outlook for IS workers. If cloud computing customers spend less on expensive infrastructure investments, they potentially have more money to reinvest in strategic efforts and innovation. This trend means the potential for more new entrants across industries, and since start-ups can do more with less, it's also influencing entrepreneurship and venture capital. In short... 1. Clouds may also lower the amount of capital a firm needs to launch a business, shifting power away from venture firms in those industries that had previously needed more VC money. 2. Clouds can shift resources out of capital spending and into profitability and innovation. 3. Hardware and software sales may drop as cloud use increases, while service revenues will increase. 4. Cloud computing can accelerate innovation and therefore changes the desired skills mix and job outlook for IS workers. Tech skills in data center operations, support, and maintenance may shrink as a smaller number of vendors consolidate these functions. 6. Demand continues to spike for business-savvy technologists. Tech managers will need even stronger business ....their time on strategic efforts. These latter jobs are tougher to outsource, since they involve an intimate knowledge of the firm, its industry, and its operations. 7. The market for expensive, high margin, sever hardware is threatened by companies moving applications to the cloud instead of investing in hardware. 8. Server farms require plenty of cheap land, low cost power, ultrafast fiber-optic connections, and benefit from mild climates.

What is data, where does it come from, and how is it an asset?

Data refers simply to raw facts and figures. Alone it tells you nothing. The real goal is to turn data into information. Data becomes information when it's presented in a context so that it can answer a question or support decision making. And it's when this information can be combined with a manager's knowledge—their insight from experience and expertise—that stronger decisions can be made.

Database Managment System

Database management system (DBMS) a program with 3 functions 1.Create 2.Process (Edit, Update) 3.Administer refers to software for creating, maintaining, and manipulating data. DBMS and databases are different DBMS a licensed software program Database a collection of tables, relationships, and metadata

Geotargeting

Much of this targeting occurs whenever you visit a Web site, where a behind-the-scenes software dialogue takes place between Web browser and Web server that can reveal a number of pieces of information, including IP address, the type of browser used, the computer type, its operating system, and unique identifiers, called cookies. IBM has used IP targeting to tailor its college recruiting banner ads to specific schools, for example, "There Is Life After Boston College, Click Here to See Why." That campaign garnered click-through rates ranging from 5 to 30 percentM. Moss, "These Web Sites Know Who You Are,"

internet has brought about cloud which changed the way we access parts of the ecosystem...explain how. Also explain how the business model and pricing is different for cloud when compared to the traditional model.

SEM

The practice of running and optimizing search engine ad campaigns is referred to as search engine marketing (SEM)

Why is Google giving the Android operating system away? What is its incentive to do this? When analyzing advertisement performance know how the following actions are taking for different combinations of Probability of Transaction and CPC?

One reason: The company believes giving Android away for free increases the size of the world's Web-connected population. The company believes that increasing the Web-connected population will inevitably lead to more Google searches — which Google can monetize with search ads. Is Google's theory correct? There is some new evidence to suggest the answer is yes. KNow the chart ! Read more: http://www.businessinsider.com/chart-why-google-gives-away-android-2013-12#ixzz2wzEPcwN5 Market Cap: Market capitalization (or market cap) is the total value of the issued shares of a publicly traded company; it is equal to the share price times the number of shares outstanding.[2][3] capitalization could be used as a proxy for the public opinion of a company's net worth and is a determining factor in some forms of stock valuation. Mega-cap: Over $200 billion Large-cap: Over $10 billion Mid-cap: $2 billion-$10 billion Small-cap: $250 million-$2 billion Micro-cap: $50 million-$250 million Nano-cap: Below $50 million

What kind of ads does Google make money in? What is the different between Google Adwords and Google Adsense? How does Google use its analytical data to target Adwords candidates? What network strategies is Google leveraging to gain network effects?

Over two-thirds of Google's revenues come from ads served on its own sites, and the vast majority of this revenue comes from search engine ads. These ads are keyword advertising, meaning they're targeted based on the words in a user's search query. Advertisers bid on the keywords and phrases that they'd like to use to trigger the display of their ad. If an advertiser wants to display an ad on Google search, they can set up a Google AdWords advertising account in minutes, specifying just a single ad, or multiple ad campaigns that trigger different ads for different keywords. Advertisers also specify what they're willing to pay each time an ad is clicked, how much their overall ad budget The Google AdSense program differs in that it delivers Google AdWords ads to individuals' websites. Google then pays web publishers for the ads displayed on their site based on user clicks on ads or on ad impressions, depending on the type of ad. Google rakes in billions on what amounts to pocket change earned one click at a time. Most clicks bring in between thirty cents and one dollar. However, costs can vary widely depending on industry and current competition. Geotargeting occurs when computer systems identify a user's physical location (sometimes called the geolocation) for the purpose of delivering tailored ads or other content. On Google AdWords, for example, advertisers can specify that their ads only appear for Web surfers located in a particular country, state, metropolitan region, or a given distance around a precise locale. They can even draw a custom ad-targeting region on a map and tell Google to only show ads to users detected inside that space. Google determines ad rank by multiplying CPC by Quality Score. Ads with low ranks might not display at all. Advertisers usually don't pay their maximum CPC. Instead, Google discounts ads to just one cent more than the minimum necessary to maintain an ad's position on the page—a practice that encourages higher bids.

What are platforms and how do they contribute?

Platform is something you can build on top of like facebook - now you can imbed part of facebook into your own site Ex. Facebook is the platform for hoot and independent site that injected into the facebook interface Facebook createa a platform for developers to create apps

How is On-Demand software (SaaS) different than traditional software? Why would a software vendor chose to offer a SaaS offering over traditional offering?

SaaS allows: 1 non-IT people out of the IT business. So they can Focus on strategy, not keeping lights (Horizon 1) 2 Reduce HW and distributing load saves $ 3 Faster deployment times 4 Not as costly, especially up front 5 No large upfront cost for HW, SW, DMBS 6 No need to hire any of consultants like Accenture or IBM 7 Remote access and availability 8 Scalable systems - can add more serves with a larger upgrade - no need to add hardware and connect it in a basement

How does packaged or custom ERP software that you install on your premise different from SaaS, which is accessed over the internet? Why would you decide to go with packaged ERP? What would be the argument to go with customized (i.e. more unique and expensive) ERP?

Privacy Concerns - not really bc thousands of users so think croud sourcing for debugging 1 But...if depend on site to house all info and company goes belly up then you loose all the data to your company. Data is store off-site ** quite a bit of lock-in with SaaS vendors, too. And in addition to the switching costs associated with switching on conventional software platforms, switching SaaS vendors may involve the slow and difficult task of transferring very large data files over the Internet. 2 Give up "control" in receiving or turning away new features **if forced to switch to upgrade... Firms that buy and install packaged software usually have the option of sticking with the old stuff as long as it works, but organizations adopting SaaS may find they are forced into adopting new versions. This fact is important because any radical changes in a SaaS system's user interface or system functionality might result in unforeseen training costs, or increase the chance that a user might make an error. Traditional? 1 More expensive but you can cusomize your entire Value Chain complexity - Fresh Directs asset is that its innovative with the way its technology is strucuted

API

Programming hooks, or guidelines, published by firms that tell other programs how to get a service to perform a task such as send or receive data. For example, Amazon.com provides APIs to let developers write their own applications and Websites that can send the firm orders. Ex. SnapTrends has an API to apply its social media data on top of google maps software Application Programing interface - doorway for those with the right key Ex. Gmail, Maps, Reader API from Google Opensup libraries of data that you can put on your site

Organic (or natural) search

Search engines use different algorithms for determining the order of organic search results, but at Google the method is called PageRank,a kind of popularity contest. Web pages that have more pages linking to them are ranked higher.

Cloud Computing/What are the benefits and risks for companies USING cloud computing?

Risks of SaaS: 1. lock-in - switching SaaS vendors may involve the slow and difficult task of transferring very large data files over the Internet. Having all of your eggs in one basket can leave a firm particularly vulnerable. 2. loosing data - If a traditional software company goes out of business, in most cases its customers can still go on using its products. But if your SaaS vendor goes under, you're hosed. They've got all your data, and even if firms could get their data out, most organizations don't have the hardware, software, staff, or expertise to quickly absorb an abandoned function. 3. loosing your SaaS provider: the number of SaaS vendors dropped from seven hundred members to four hundred 4. requires constant adaptation forced into adopting new versions. This fact is important because any radical changes in a SaaS system's user interface or system functionality might result in unforeseen training costs, or increase the chance that a user might make an error. 5. Potential for slow access to data: Keep in mind that SaaS systems are also reliant on a network connection. If a firm's link to the Internet goes down, its link to its SaaS vendor is also severed. Relying on an Internet connection also means that data is transferred to and from a SaaS firm at Internet speeds, rather than the potentially higher speeds of a firm's internal network. 6. security fears: here may also be contractual or legal issues preventing data from being housed remotely, especially if a SaaS vendor's systems are in another country operating under different laws and regulations. "We're very bound by regulators in terms of client data and country-of-origin issues, 7. consumerization of SaaS: Here's another challenge for a firm and its IT staff: SaaS means a greater consumerization of technology. Employees, at their own initiative, can go to firms such as Socialtext or PBworks and set up a wiki, WordPress to start blogging, or subscribe to a SaaS offering like Salesforce.com, all without corporate oversight and approval. This work can result in employees operating outside established firm guidelines and procedures, potentially introducing operational inconsistencies or even legal and security concerns. In Summary: 1. dependence on a single vendor. 2. concern about the long-term viability of partner firms. 3. users may be forced to migrate to new versions—possibly incurring unforeseen training costs and shifts in operating procedures. 4. reliance on a network connection—which may be slower, less stable, and less secure. 5. data asset stored off-site—with the potential for security and legal concerns. 6. limited configuration, customization, and system integration options compared to packaged software or alternatives developed in-house. 7. the user interface of Web-based software is often less sophisticated and lacks the richness of most desktop alternatives. 8. ease of adoption may lead to pockets of unauthorized IT being used throughout an organization. Benefits of SaaS:

Ex of Databse Commands

SELECT first_name, last_name FROM Records WHERE last_name = 'Smith' On the website, write a SQL Statement that pulls the count of suppliers from the suppliers table. Once you have a working statement SELECT Count SupplierID FROM Suppliers **note that Suppliers = a field while SupplierID is the primary key within the Suppliers field Select Distinct CustomerID from Order **this means that the database will not bring up duplicated CustomerIDs SELECT CustomerID, CustomerName FROM Customers Order by City Ascending SELECT* FROM Suppliers Sort by City DESC;

To select all

SELECT*FROM Customer WHERE city = Berlin

SQL

SQL (pronounced "sequel"). SQL stands for Structure Query Language and is the standard language that is used to access and manipulate data and databases. With SQL you can execute commands known as "queries" that will either retrieve data, insert data, update data, or delete data. You can also do other administrative things that we're not going to cover today like add/change tables, set permissions, and more. Why would someone use SQL? Anytime you want to store data, updated it, or retrieve it quickly in reports AND the data is too complicated (due to the amount or type) to manage in Excel, a DBMS can be used to maintain this in a database. SQL is the language you use to manage the data in the database.

What are the various internal and external sources for data?

Survey Data = Just ask the customer Actual survey Blog or FB page (Netflix) Customer Transaction Systems Where does Zara get sales data? POS = POINT-OF-SALE SYSTEM Where does CVS get buying habit data? Loyalty Card Program Enterprise Software How do sales affect inventory in the store? How does that affect activity at Warehouse? Can also buy data or find it online in directories

Net Neutrality/ Circuit/Packet switching

Take information into packets (binary code) Turning text into binary code - this create packets; this allows information to be chuncked and sent out on multiple paths and then reassembled into its orginial message on your browser • Tags the message in code, where its coming from and where its going (IP Address), and what place in file • When a message is sent the packets go down fastest paths (has the ability to reroute)

WWW

The World Wide Web (abbreviated as WWW or W3 and commonly known as the Web) is a system of interlinked hypertext documents accessed via the Internet

Push Advertising

Traditional advertising. SEM is more pull advertising

How are IP addresses related to URLs? What parts make up a URL?

URL = uniform resource locator, tells your browser what your looking for in a way that a normal person recognizes IP address: tells the computer what you are looking for in a way a computer understands. Ex. 129.232.82.210 URLs may list the application protocol, host name, domain name, path name, and file name, in that order. Path and file names are case sensitive TCP/IP, or the Internet protocol suite, helps get perfect copies of Internet transmissions from one location to another. TCP works on the ends of transmission, breaking up transmissions up into manageable packets at the start and putting them back together while checking quality at the end. IP works in the middle, routing packets to their destination.

How is SQL used to manage data in a database?

UT ID: Unique Identifier, Record Locator (for Southwest to look up your flight number) Levels (from core to outer) 1. Database: Tables, Metadata, Relationships 2. DBMS: Database Management System 3. Database Application: Application Programs Record - instance relating to a primary key aka a row within the database Primary Key - Unique identifier for the field Logic of Database Each Table focuses on one theme

Internet Pure play

Warehouse model thats close to UPS stores - this allows for the longtail fo movie rental demand to help netflix make more profits

Net Neutrality/ Analog vs. Digital signal

analog: calls connected through switching stations - party lines; Phones travel as sound waves that can't be broken up like digital signals digital:

What was the downside to Netflix's early IPO? Also why did other firms find Netflix's market attractive? What advantages does the longtail give online firms (e.g. like Netflix) that actual stores can't capture and why? What does it mean to drive customers into the longtail and how does Netflix do this?

driving customers into longtail means getting them to watch the more obscure movies just like iTunes makes recommendations of songs that are less popular (again tapping into long tail)

What was the military's reason for fueling innovation in NASA and ARPA? What sort of institutions housed the initial 4 mainframe computers connected to the ARPAnet and what were their incentives to contribute to the ARPAnet?

fear of russians, communism and atomic bomb. fear of soviet space mastery. Designed as a computer version of the nuclear bomb shelter, ARPAnet protected the flow of information between military installations by creating a network of geographically separated computers that could exchange information via a newly developed protocol (rule for how computers interact) called NCP (Network Control Protocol). first data exchange over this new network occurred between computers at UCLA and Stanford Research Institute. On their first attempt to log into Stanford's computer by typing "log win", UCLA researchers crashed their computer when they typed the letter 'g'. Four computers were the first connected in the original ARPAnet. They were located in the respective computer research labs of UCLA (Honeywell DDP 516 computer), Stanford Research Institute (SDS-940 computer), UC Santa Barbara (IBM 360/75), and the University of Utah (DEC PDP-10). As the network expanded, different models of computers were connected, creating compatibility problems. The solution rested in a better set of protocols called TCP/IP (Transmission Control Protocol/Internet Protocol) designed in 1982.

Host Domain Name Top level Domain Path File HTML IP Address

host - specific server computer or collection of computers (usually referese to the 'www' of a web address Domain Name - the name of the network you are trying to commect to. Ex its the 'newyorrktimes' portion of www.newyorktimes.com/style Top Level Domain: ex. "com" Path & File - Tell the browser and later the web server the specific path and name of the file on the server you are looking for * these are both case sensetive Ex. www.newyorktimes.com/"style"."html" Style is the path html is the file type HTML - Web servers and browsers can deliver about any type of file, but the most common one is a ".html" file IP Address: IP address is a value used to identify a device connected to the Internet. It is usually expressed as four numbers (each from 0 to 255), separated by period. ex. Website host www.utexas.edu IP address 124.14.234.179
