How does this work? What is nfc used for? Can this be used for pay phones? sept 12 - 13 Chut rebecca

How does this work? - NFC tags are just RF chips. They use radio frequency to communicate with each other. What is NFC used for? - They can be used for many purposes. Since that it can communicate with other devices that use NFC tags as well, it might be used as a credit card-like payment device, being to pay for something by just your phone. Anything that also uses NFC tags may be synchronized to work together. Can this be used for pay phones? - Yes it can. If payphone also have NFC tags, people may be able to call without having to insert a coin or a card.

Da Woon November 1st  Describe the IT system

This article tells us the air traffic controller (ATC) which helps us to have safe fly. ATC has access to sophisticated radar systems that provide an overview of the airspace they control, and they have communication tools to coordinate flight paths with the air crew. When the aircraft travel at higher speed than common modes of transport, the time available for pilots to react to a dangerous situation can be quite short. And ATC helps to aircraft approaching an airfield carefully and it checks the weather conditions for prevent pilots can't see other aircraft. ATC uses radar systems positioned at ATC facility to get a real time overview of the aircraft flying in the airspace they control. Many types of radar equipment are served for traffic on the ground. Primary Surveillance Radars (PSR) - The radar sends a directed pulse into the atmosphere, and when that pulse encounters an object it gets reflected back to the radar station. The bearing of the object with respect to the radar station and its approximate distance can be calculated by this. The radar is typically enclosed in a dome to protect it from adverse weather. Secondary Surveillance Radars (SSR) - the Secondary Surveillance Radar listens for messages from the aircraft's transponder. The radar rotates about the vertical axis, but transmits a specific signal on 1030 MHz. This signal is subsequently received by the aircraft's onboard transponder, which responds with a reply on 1090 MHz. SSR Modes - There are different modes of interrogation that compliant transponders respond to. A - The transponder responds with its squawk code, a unique identifier for the aircraft assigned by ATC comprising of four octal numbers. This code enables ATC to differentiate between the various aircraft being monitored, though it can also be used to discretely communicate the existence of an emergency situation onboard the aircraft. C - the transponder responds with the aircraft's pressure altitude, which is the altitude ab

1. Identify the scenario. Business 2. Describe a social/ethical concern and the relationship of one primary stakeholder to the IT system in the article. Security is a social/ethical concern because it regards the security of the Database Servers that are used to store the Domain Names and IP addresses. With insufficient security, the database security can be breached by outsiders and be altered. The primary stakeholder is Group NBT, and is the domain name management firm of NetNames and Ascio whose DNS Databases were compromised in this attack. Their SQL commands were infiltrated by the hackers, so that the information stored on their DNS Database was altered, that made website visitors be re-directed to spam websites. 3. Describe the IT concepts and processes. Domain Name System (DNS) - The address book for the website that links the URL of websites to IP address numbers that computers use to visit a website. IP Address - The numbers that are separated by period dots that make up a website's numerical address of its location. (DNS) Database - A database is a massive spreadsheet with numerous data types and forms used to store large amounts of data (in this case, websites' domain names URL and their respective IP addresses.) SQL Injection - SQL stands for Structured Query Language, used for database manipulation. This is a hacking method by using the various layers present in SQL commands, by 'injecting' a hidden command that enables to create a loop hole for access and change the database information. This includes changing strings of commands in the original SQL command into malicious commands, that are executed when the altered SQL command is executed. http://msdn.microsoft.com/en-us/library/ms161953.aspx

4. Explain the relationship between the IT system referred to in the article and the concern presented above. The security of the DNS Databases run by NetNames and Ascio (two subsidiaries of domain name management firm Group NBT) is a concern. Their SQL commands were being altered and compromised, which resulted in the altered domain names and IP address links. Their relationship is that the concern is the IT system's (in this case the Database's) security. The IT system, Group NBT's Database, has a concern over it's security. The DNS Database system has a security concern because the hackers were able to alter the paths of redirecting certain websites to scam websites instead through a SQL Injection attack that manipulates the SQL command used to manipulate the domain name database. 5. Describe and evaluate the impact of a social/ethical issue on the stakeholders The social/ethical issue is security. The stakeholders are Vodafone, the Daily Telegraph, UPS, and four other websites, Turkish hackers (Turkguvenligi), and internet users who visited those seven websites within the hacking duration. This has an impact on their security issue because their database has already been compromised once, and unless they create a new system of security to prevent SQL injections, they will never be able to know when someone is changing their SQL command strings. They need to have someone constantly monitoring their SQL to see if there are any changes. The security issue impacts Group NBT because it makes their customers that use their services doubt the secure service because hackers were able to alter the redirection of customers to scam websites instead of their respective website. Therefore security, to a large extent, has an impact on Group NBT. 6. Explain and evaluate one solution to the issue identified. A solution to the issue identified by NBT was to further review their Database system to ensure customers of a more secure service, since it is impossible for a

Which would you use? march 17 kuni

I would use Google Sketchup, because this is one of the applications that I have on my computer. Google Sketchup is a software with which you can make a 3D model easily. Compared to the other 3D modeling software, Google Sketchup is easier to use. It has some tutorials for beginners, and you will find out how easy it is to create 3D model like a kid making a tower of blocks. Also, if you buy it, you will be able to convert it to a file that can be used for other 3D modeling software and modding games. I would use Google Trends just to see what's trending and Flight simulator in Google earth sounds pretty fun for when you're bored. I would use ; Google Page Creator, Flight simulator in Google Earth, and SketchUp. I would use the fight simulator, because it looks fun, and SketchUp mainly because I've always wanted to do some sort of graphics design on the computer. -In my opinion I would like to use Google SketchUp, and Google Book Search. First of all Google Sketch Up is helping me to make 3-D model. This is very useful in art class because when we have something like installations, we need some sketch of location and installation therefore by this program, I can draw 3-D installation and see how it looks like therefore this program is very useful for me. Also For the Google Book Search, this is kind of digital library which I can find book very easily and efficiently. I can see the books by this program also I can upload by own books which I can scan it. Therefore it might be very useful when I have something like writing essays. I would use Google Page creator. It enables to me create a page where I can find snippets of web pages, quotes, and images all over the web.

manned aircraft couldn't provide. Also, UAS could be used to fly in to observe or take samples after a chemical or biological attack. Any missions too dangerous for manned aircraft will be taken care of by the UAV. UAV have other advantages over manned aircraft as they have more detailed information about their targets, their strikes are more accurate and cause fewer civilian casualties. They are also cheaper and smaller. Since they have no pilot, the space could be used for fuel and thus they can fly much longer than manned aircraft. Without the need to accommodate crew, drone can be given radar-cheating stealthy shapes and can maneuver better. There are however a problem afflicting the drones as they depend on two-way satellite communications. If the datalink is broken the remote pilot will lose control of the aircraft. For missions requiring constant oversight, the vulnerability to electronic jamming or a direct attack on a communications satellite is a huge problem. Another problem is that the dones has a slight delay between the remote pilot and the aircraft. To reduce latency, small, solar, or laser powered ultra long endurance drones can form a chain in the sky along which satellite signals can be bounced. To reduce the workload on pilots, big UAV can take off and land automatically. The US Air Force plans to have a pilot operating up to four drones at a time. Civil liberty advocacy groups have raised concerns about targeted killings by drones. Bus as long as a UAS pilot can trust data from remote sensors, he or she should be able to make a proper assessment the same ways as the pilot of a manned aircraft. UAS pilot will be in a better position to do so since he or she will have more time to assess the situation accurately and not be exhausted b the physical battering of flying a jet.

Allowing the UAV to fire a weapon based entirely on its own data analysis raises a lot of ethical problems. Using UAV to kill enemies thousands of miles away is like a cowardly action of a bully sheltering behind superior technology. There are fears that UAS will lower the political threshold for fighting and an essential of restraint will be removed. Drones make leaders fonder of war.

The Piracy Problem: How Broad? Why are copyright violations are a serious problem? Copyright violations are a serious problem because it is equivalent to stealing. A person who watches from free online movies doesn't realize that all the people behind the movie used their time, labor and energy to create that movie, not to mention the amount of money that was used to produce the movie. So, to broadcast it to as free movie is truly unfair for all the industries concerned. Describe two advantages and two issues with illegitimate downloading. Advantages: (1) People around the world who can't afford to have it have the option of having for free. (2) It is available anytime, anywhere in the world. Issues: (1) Million of dollars as revenues and earnings are stolen from industries (movie, music, TV, etc.). (2) It will cause the affected industries to increase the price of their "product" when purchasing it legitimately. Explain two possible solutions to this kind of piracy. Possible solutions: (1) If people around the world really see stealing as a morally corrupt practice, then let us all shun away from the use of the internet. (2) If we can't afford to avoid the disadvantages of the Internet, let us all practice, encourage and teach honesty. This golden virtue is the only potent cure against SOPA and PIPA. Not enough is being done to tackle cyberbullying, according to the NSPCC. Give examples of cyberbullying. Some examples of cyberbullying are the following: receiving nasty text messages or e-emails 24/7. Describe possible solutions. Some possible solutions are the following: students must not give their mobile number to acquaintances or other students who are their close friends; never chat to anyone whom you don't know; when you received nasty text messages from your mobile phone, change your mobile phone number right away; and lastly be very selective in choosing whom to friend in FB or in other social networks.

Does the Net allow more freedom or is it a tool for governments and businesses to control us? The Net allows both. The users can roam freely to their discretion where and what they want to put onto the web. It is just a matter of a country censoring the content, or the user self-censoring what is to be put on the web. Also, the governments and businesses both can use the Net to their advantage. The government can learn and find out various information of various individuals and trends of the public through the Net's social networking websites and other portal that have discussion between citizens themselves. Business are able to keep track of trends to see what is happening, such as the stock prices to what people like to eat, listen to, what they like to use. Thus the businesses are able to stay in business a little easier through knowing the information from the web. The businesses can also advertise themselves through the net, and that way, it is actually faster than having actual offline campaigns and advertisement. Therefore, the net can allow us both. We are free to use it more than let it control us. It's just a matter of fact that higher class society, social ranking, or economic status-ed has more chances to controlling the net due to their connections with the higher ups. Yet, censorship and surveillance is everywhere, and thus doesn't allow absolute freedom.

Why is cloud computing gaining widespread adoption? Why is it cheaper? Describe saas Describe the Tangerine example. What kind of customers does salesforce target? How does cloud computing encourage collaboration? march 17 soo

1.Why is cloud computing gaining widespread adoption? Cloud computing is gaining widespread adoption because cloud computing enables users to connect to corporate data and applications via online enabled devices. It offers the complexities and unique requirements of sophisticated applications, yet delivers them in less time and with lower startup costs. 2.Why is it cheaper? Cloud computing is cheaper cost when they deliver IT systems because businesses pay for only what is used and by that they could reduce the amount of cost in capital and operating cost. 3.Describe SaaS. SaaS stands for Software as a Service. Users who use services that is net-based are charged for the software they used, either as a subscription or as a pay-as-you-go basis. It is basically charging the service costs for the software that the users are utilizing. 4.Describe the Tangerine example. Tangerine is a company that sells enterprise version of Google mail and applications. These applications uses Gmail or Google's online document systems as an interface. Users who use Tangerine are charged a subscription fee for the usage of Tangerine. 5.What kind of customer does sales-force target? Salesforce is targeting people who actively use clouding computing system. Basically, it could be individual people but mostly many huge companies are using clouding computing to work efficiently. Also this system could save the money for the storage systems. 6. How does cloud computing encourage collaboration? By using user-friendly services like Facebook rather than conventional e-mail, feeds rather than memos, a touch-based system rather than a click-user interface, a push-based information system rather than pull or browse, location-based technology rather than unknown locations, and web service/HTML rather than Windows or Mac.

How is twitter used as a barometer? Explain the potential uses of networks as barometers? m12 october 10 jenny

How is twitter used as a barometer? Twitter is used as a barometer because of its users' tweets that update happening events in real time, and can be used to know the change of events in real time.

Authentication- Authentication is the process of determining whether someone or something is, in fact, who or what it is declared to be. In private and public computer networks (including the Internet), authentication is commonly done through the use of logon passwords. Knowledge of the password is assumed to guarantee that the user is authentic. Each user registers initially (or is registered by someone else), using an assigned or self-declared password. Tokens- A Hardware Token is an Authenticator in the form of a physical object, where the user's interaction with a login system proves that the user physically possesses the object. Hardware Tokens authenticate users on the basis that only the Token assigned to the user could have generated the pseudo-random number or code response keyed in by the user. Successful entry of this code implies that the user is in physical possession of the Token. This implies that the user does not allow users to use his Token, and has not lost it. It is use to prove one's identity electronically, and it is small enough to put it in the pocket or attach to keychain. Smart Card-A card with an embedded computer chip on which information can be stored and processed. It is a plastic card about the size of a credit card, with an embedded microchip that can be loaded with data, used for telephone calling, electronic cash payments, and other applications, and then periodically refreshed for additional use. Biometric- Biometrics is the science and technology of measuring and analyzing biological data. In information technology, biometrics refers to technologies that measure and analyze human body characteristics, such as fingerprints, eye retinas and irises, voice patterns, facial patterns and hand measurements, for authentication purposes.

Two passenger who are from Iranian used fake passport to board on the flight 370. Malaysiann home minister Datuk Seri Ahmad said that using Interpol's Stolen and Lost Travel Documents (SLTD) database might have slowed down the process of immigration checks at airport counters. He said the country's immigration's equipment couldn't handle the global database of 40.2 million lost passport. Later on Interpol fired back by saying that do not blame on technology or Interpol. SLTD database takes just seconds to reveal whether a passport is listed, with recent test providing results in 0.2 second. Also Interpol mention that US using more than 230 million times, UK using more than 140 million times, UAE using more than 100 million times, Singapore using 29 million times, none of the countries have complained about the time.

How would this help you? These tools could help us by providing us with at least some more sense of security that what we barely have left now. Because we are often on the Internet, we are exposed to the danger of being seen and tracked by others. These tools help us stay invisible and informed. The use of encryption is used as well as proxies to hide user IP addresses. The free tools are basically for us to be aware of what is being tracked of our online activity, and how we can prevent it with the software.

This is a disposable email that only lasts for one hour then erases itself. This could come in handy if you have to give an email address to make a game account you could use it so that you don't get spammed from the game site. Also it would make it impossible to track information sent from that email address to someone because it erases itself after one hour after being activated. You do not have to create your name because the site gives you an example. When I opened the site it told me that my email address was ready for use and was (owbjehey@guerrillamailblock.com) however you could change the name and use that as long as it has not been used before or is in use now.

Why might smart phones be costly? Explain two possible solutions. all Nov 23 Tik

Smart phones could be costly because it's download, upload and connect to the network almost all the time. People that use smart phones and don't have good deals or promotions,and people use data more than they think, so the phone company can cost the data that we download, upload with the network, and smart phones can do many thing that use a lot of data and it will cost a lot of money, for example sending 10 photos it's take 10MBand watch video on youtube it will take 15MB per video, etc. In this case the solutions are that users should make sure that they get the right deal or promotion, that they won't get a big bill in the end of the month. Secondly, there are people that use unlimit promotion, but every deal have a gap, so the phone company should tell their customers, or send the users a messages to warning them that they used data more than the deal they got.
