3.4 Images and Graphics

In DITA on October 25, 2009 at 11:52 pm

This week in DITA we have been looking at Graphical image formats.

Raster images

Raster images work well for complex graphic such as scenery as they record continuous information. Cells are usually arranged in a grid and each cell has a numeric value that represents its content. These cells are often referred to as picture element or pixels for short. (Butterworth,2009)

GIF, JPEG and PNG

GIFs were developed by Compuserve in 1987.  GIF Files support 256 colours as they are in a 8-bit format meaning they record 8-bits of information for each of the pixels. Because of the limited nature of GIF files they are better to use for logos or line drawings. GIFs can also be animated unlike JPEGs which are static images. ((Butterworth,2009)

JPEG’s were developed by the by the Joint Photographic Experts Group. JPEGs are able to support 16 million colours because of iTs 14-bit format. Compression is more successful in JPEGs than in GIFs as JPEGs employ a technique called lossy where the colours are subtly modified by creating patterns. The loss in colour data is not normally detectable to the human eye which means that JPEGs are very good at storing photographic information.

PNGs like JPEGs are in 24-bit format but they compress images without the lossy technique. However the PNG files tend to be larger than JPEGs.

Image formats is important in web design because large files can affect the  time a page takes to render. Depending on the topic of your page you would have to decide whether to compromise on resolution or page rendering.

Vector images are different because they are made up geometric point, lines and curves which are based on mathematical equations.

Here is a link to an embedded formatted image that is blocky because of the pixels. http://www.student.city.ac.uk/~abhd831/imagereturn.gif

3.3 The Internet and World Wide Web

In DITA on October 18, 2009 at 10:46 pm

This week in DITA we have been looking at the Internet and World Wide Web. Before this week’s lecture I had always thought that the Internet and the web was the same thing. The confusion seems to come from the fact that we use the terms interchangeably.

The Internet

The Internet essentially is the structure that holds the web. The Internet started life as ARPANET and was first created in 1958 by The Advanced Research Projects Agency (ARPA) to link all the radar systems of the US together. In 1969 the University of California in Los Angeles (UCLA) got hold of ARPANET and since then strides in technology have culminated in the Internet we have today. It is a massive network of networks allowing each connected computer to send information to each other using protocols. Other subnetworks also run on the internet for example email uses SMTP. The diagram below shows others.

The World Wide Web

The World Wide Web was invented in 1989 by physicist Sir Tim Berners Lee. It runs on top of the Internet. The web is made up of large-capacity computers known as web servers which are connected to the Internet through telephone and satellite. Web servers use HTTP protocol to allow computers that are connected to any web server to access files across the web. Files are accessed across the web via web addresses otherwise known as Uniform Resource locator (URL). A URL is made up of the protocol HTTP, the domain name – name of computer hosting the file and the path to the file itself.

In my last post I was introduced to the concept of including Metadata. HTML or Hypertext Markup Language is a form of markup language designed by Tim Berners Lee where HTML tags are used to indicate to the web browser how the web page should be structured.

In this week’s lab we were required to design and link web pages hosted on our City web space.

Here are the web pages I created in this weeks session.

2nd Week in Dita (3.2 text/Html)

In DITA on October 11, 2009 at 8:18 pm

This week In DITA we have been looking at the representation and storage of data. As humans we are used to our counting system being based on base 10 (Butterworth,2009) with computers this is not the case, computers count in base 2 known as binary. Binary code is a series of zeros or ones which are supposed to be the different states a computer can have ON or OFF.  For example the number 157 would be 10011101 in binary. To be honest I struggled with the concept  of binary at first but i found a very helpful tutorial here. A single zero is known as a bit and a sequence of bits equals a byte. Bytes put together form files.

So how does all these bits become text? The answer is ASCII.  ASCII or the American standard code for information interchange is a system of computer code in which seven bit sequence can be encoded as 128 characters. For e.g 100 0010 equals the uppercase letter B in ASCII.

As the ASCII character set is so basic, it is more commonly used for writing source code for Windows control files such as Config.sys, and Win.ini.  It also used to for transfer data among applications that do not share a common file format. For example files that are edited in Notepad and saved with the .TXT extension can later be opened by word processors such as MS Word.

During our lab session we were asked to open a Microsoft Word document with a .DOC extension in Notepad. When we did this we were able to see that Microsoft documents contain Metadata. Metadata is essentially data about data it is used to describe, locate  and retrieve information more easily. In a typical Microsoft word document metadata can include the name of your computer, the names of previous document authors and template information. A way of including Metadata is through Markup. I will go in more detail about Markup in my next blog when talking about Html.
