Javascript and beyond

Some people confuse Java and Javascript to be the same. However they are not, Java is a programming language, whereas Javascript is a language used in web development. Javascript needs to tell the programme to tell the programme when to start, the code in which it needs to read and when it needs to stops.

Javascript is used widely across the web because the static pages that are produced by HTML and CSS are not enough. Javascript a type of client side scripting that allows the designer to carry out bigger jobs. For example a use will need to fill in a form, the designer can use Javascript to ensure certain field have been completed. There are various over web client server languages such as TCL/TK and VB Script that also allow this to be done. The only difference between the languages is the variables and syntax used to create the code. However the HTML language is still important because it must come before and after the scripting language.

The person the web site belongs to can design the script using Structured English or pseudo code. Although the choice of language actually used, to create the website, is completely up to the designer. This will depend of the speed, transferability and how suited it is to the application it is being implemented on. In addition due to Javascript being browser based, it cannot handle the bigger jobs. For example it cannot save the information that was entered into the form. Therefore server side scripting is needed. Languages such as Ruby on Rails which is used by Twitter, Yellow Pages and Groupon, can carry out the task of saving information entered into a form.

In reflection this blog was done completely from lecture material and therefore could have had more of my own content into it. However it did have plenty of examples in, where other blogs may not have. I have fully understood this material and as the weeks have proceeded, which allowed me to gain an understanding of how complex the web can actually be. Although I could have been more active inside and out of the blogging community, which would help me gain a deeper understanding of the topics I have written about. It would also enable me to write more concisely and as explored written in a more scannable manner. I could have also gone into more detail on posts and the done more reading, to understand certain topics that where not as easily understood.

Week 15- Quicker Scanning of the Web

Over the past few weeks I have been writing about various pieces of the web. This week reading is focused on the statics and methods of how people read the web, as well as how it is different to print. When writing content for the web, people are busy and want to find the information they are looking for as quickly as possible.

scanning webpages

Recent studies have shown that writing concisely, adding in keywords and using hyperlinks to highlight key points in a paragraph to shorten pages is the best way to keep readers attention. In addition adding sub heading also help because it allows the user to go straight to the paragraph they are interested in. In addition bullet pointed lists are also more effective than thick chunky paragraphs.

Studies have shown that:

When written more concisely, scannable and objective, they were 124% higher in measured usability.

When only one of the above were improved on a webpage, it only achieved around 27% to 58% more in usability.

When pages were rewritten they achieved 159% higher than the original webpage in usability.

(It is important to note that these studies may have issues with reliability and some studies do vary slightly in percentages, this is due to research on this topic still being in its infancy.)

Furthermore it is important to note that webpages are different to print. Print is all about catchy headlines, which are vague to interest the reader. They are also designed to story tell and entertain those viewing the story. However webpages are meant for information and users want this information as fast as possible. This is because the web is so large and is used daily to find out facts across the globe unlike television and newspapers which tell most stories locally or have an entertainment value. As a result the content of a webpage is not only important to get users to view it but also to get to the top of the search engines. This explains the importance of the job information architects have, that I have mentioned in previous weeks.

Upon reflection I really enjoyed doing this post because I really understood the topic for this weeks. I was also able to add my own content and multimedia elements. However I could improve on my sentence structures and how I writing for the blog, this could be done by writing more concisely. In addition the sources I have chosen have come from an ordinary Google search, I could use a meta search engine to improve the quality of my findings or I could use a search engine like Goggle Scholar. This would give me better quality documents, which are more credible academically.  I should also because more active in the blogging community and look at other people’s posts, to gain wider knowledge each week, on each topic.

Have a look at these Youtube video’s for more information:

Week 14 – Safety and Security on the Internet

It is easy to be secure on the internet with the large amounts of anti- virus software available to internet users. However there is a big difference between security and safety, which many people do not think about. When being secure on the internet products, such as Norton 360 and turning on the computers firewall, can ensure that your computer and the information on it is safe from hackers and virus’. However no product can ensure safety as this is purely human behaviour.

Safety is usually how criminals get their information for example, sending a vulnerable user spam or an email posing as the bank. This tricks users into believing the bank has contacted them, due to an issue with their account. As a result the user types in all their PIN numbers and passwords which are being watched by hackers. Consequently this information is in completely the wrong hands and whole bank accounts are emptied of their money.

Moreover although new technologies, are allowing for bigger risks new advanced protections are being invented, like the AVISPA tool which checks for attacks on the input protocols. Similarly the internet can pose other risks such as addition. Currently internet addition is not a recognised illness however those with impulsive traits like gambling, do tend to experience addiction to the internet. Studies have been carried out and as the internet is growing, so are the users and in particular the gamers. For example China in 2009 increased by 28.9 percent with regards to users of the internet. (Study on Causes and Strategies of Online Game Addition among College Students, 2010) Therefore the internet may not be as safe as users think, especially as it is linked to part of the reason for the rise in obesity.

Upon reflection I really enjoyed writing this post, I understood the content really well and added some of my own content. However to improve I could be writing a little more concisely to reduce the size of the blog. In addition becoming more active in the blogging community would benefit me because it would allow me to gain feedback upon my work. This would also enable me to check my understanding and ensure all relevant points have been expressed properly.

Week 13 – Social Networking

There was no scheduled readings for week twelve, as there is a reading week every six weeks.  As a result I used this week to complete tasks outstanding within my course subject. This week the focus is on social networking and social media and the advantages it gives to businesses. Moreover exploring the cultural differences in regards to social networking.

Social networking sites like Facebook and Myspace allow business to advertise their business more, as well as having a more active presence. These sites bridge the gap between creators and the people who use the support content. It also enables creators and business to gain rich feedback, quickly. Whereas before feedback too much longer with customer support phone calls and focused interviews. Although new policies and carefully planning, guidelines and strategies are needed because social media does not suit every product or user.

Furthermore social networking for those like Koreans have great emphasis on maintaining social support from existing social relationships. On the other hand American’s place greater emphasis and importance on gaining entertainment. American’s also use social networking sites more than Korean’s because of the difference culturally when managing and developing social relationships. Social networking sites also enables news, about natural disasters and similar events to circulate to other countries faster. This allows people to get help quicker and easier, however it can print stories that are bias because countries can lose some of the control when it is uploaded onto these sites. This is similar to business and how they advertise their products and the reason it may not be suitable for some users or products (as mentioned earlier).

Upon reflection it was very difficult to go into detail on this topic because it is closely related to other topics such as security and safety. In addition multimedia elements could have been added to improve the post, as well as interactive elements such as polls. Furthermore I could be more active in the blogging community by commenting on other students posts and adding my page to external bloggers, in order to gain more interest in my pages. Plus adding my own content would support arguments and better convey my knowledge on this topic.
