The things that were missing

Been quite a time since I last posted here, well.. the group work started so the work has moved to a new blog!

Anyways, apparently there were a few things missing in my blog, which I will now add so nothing is missing.

How to sign up for a .com.ar domain?

To sign up for a .com.ar domain, all you have to do is go to NIC.AR and sign up for the domain you want.

There are however a few things you have to consider when signing up: The domain you want cannot exist already, you need a valid email address, the domain name cannot contain any form of racial offense, for example. Argentinians also need to enter their personal details as well as DNI, therefore you need a valid address in Argentina. A person can have up to 200 .com.ar domains, but nic.ar serves only for the top level domain, not for hosting any kind of data. Also, a domain name can max. contain 19 letters.

To get the domain working you have to change the DNS in the “tramites” section, as you need to get the user forwarded to where the data is hosted.

To maintain a .COM.AR you don’t need to do much, but “renew” it once a year, as they run out after a year. Signing up and maintaining the domain however is free.

Webquiz

A webquiz is a way to check someones knowledge about something. It is like an offline quiz, but comes with a few advantages.

The teacher (for example) can make a new quiz, add his questions in the form of multiple choice or “short answer”. Furthermore he can allow only specific users to take the quiz, he can set a time when the quiz starts and when it ends.

The huge advantage of a webquiz is that the answers can be added by the teacher, so a multiple choice quiz does not have to be corrected by the teacher – the system does it automatically and, if wanted, lets the user know the result and the right/wrong answers as well.

A Webquiz can be found online, some for free.. others charge for the service. The webquiz I prepared before the exam is hosted on http://quizstar.4teachers.org/

Sadly enough wordpress doesnt support an implementation of a webquiz directly in the blog, well.. cant help it.

To sum up 2 points:

You can make a private and/or public webquiz, multiple choice or open answers.

Pages that provide a quize are quizstar.4teachers.org or also free-online-surverys.co.uk

I was told that my webquiz was missing here, but as I said, i cant link it directly on wordpress.. but before the exam I sent the teacher a link and the login details for the quiz. This quiz is still published on quizstar!

Social Networks

Social Networks, such as Facebook for example, offer a huge advantage for companies – direct contact to their (possible) customers.

This means they can have an improved CRM because of getting opinions, communicating and sharing information with their customers. But they can also use the platforms to announce news and public useful information in order to find new customers.

Many well known companies are part of social networks for those reasons. Feedback comes due to communication – positive or negative feedback, the users in social networks share their opinion, which is very useful for the companies.

Facebook:

Well, on facebook you can share your opinion about basically anything, also various products. The companies can then read those opinions and try to improve their products.

Users can also become fans of the company/product, by signing up as a “Fan” the subscriber will receive news and useful information provided by the company.

Very good way to keep in touch with the customers without them actually having to do much – sign up once.

LinkedIn:

Has advantages for private users and companies, as private users can search for qualified help, for example, or see if there is a job opening somehwere. But the main advantage lies in companies finding qualified staff, as users have their career uptodate online.

Of course this is also a social network, so people can communicate and keep in touch.

SecondLife:

Well, another way for companies to keep in touch with customers, this time in a virtual world where companies actually earn additional money. Dont have to say much about it – a social network in form of a “virtual life”.. just a graphical way of a social network.

YouTube:

Well, a different way of a social network, mainly used for sharing videos. Very useful for “newcomers”, quite a few people became famous just using youtube to publish their home made music/movie/whatever audio/video.

Interesting for companies as they can upload their commercials, for example. Music producers can publish free versions of their songs in a low quality so users can see if they like it and buy it afterwards.

Most people use youtube to watch videos only, but there is a huge community behind it – communicating and sharing.

SlideShare:

Very useful especially IN a company. You can upload a presentation, even with voice comments and other people can watch it. For multinationals, for example, this makes life a lot easier.  Companies can also use this to explain a more complex product to their users – Oracle for example is doing this, but they are using their own platform, not slideshare.

Very good idea, whereby I am not seeing a network behind slideshare. Might be my lack of experience with it, tho.

Another one of my choice:

Would in this case be studivz: This is somehow like facebook, but servers as a social network for german students (stud(i) = students and VZ = Index).

A way german students use to communicate, once it was a bit more based on educational stuff, as it was for students.. now its almost the same as facebook, used by germans.

Security Question:

Which of these is a cryptographic protocol used for communication security?

TLS – Transport Layer Security

AIS – Advanced Internet Security

ABWT – Advanced Barbed Wire Tracking

FTP – File Transfer Protocol
