Accesibility
In the web world, accessibility is about how easy is a website to be used for a disable user.
Webpages use to have accessibility problems for the following groups of people: - Visual
discapacity using screen readers- auditory problems, using web browsers and computers
without sound - physical disability - colour-blind people.
Affiliate marketing
Affiliate marketing is a Digital Marketing strategy allowing for selling products from different e-commerce which are related to the sector of one particular ecommerce or with its products sold in it. These websites are own by third parties which do not have any relationship with the ecommerce ?s owner, and they allow to include these products in exchange for a small commission for every trade made through their website. Also known as associates program.
Examples: Amazon is an online shop holding an affiliates program being used by many websites, so we can find links to shop books in Amazon within many different websites.
Agent
An intelligent agent (or intelligent process) performs some information gathering or processing
task in the background, in order to get a higher level of interactivity in the webpages.
AJAX
Short for Asynchronous JavaScript and XML, it is a term that describes a new approach to using
a number of existing technologies together. In this way, it puts combines: an XHTML / CSS
presentation using DOM to interact with the web site and XML and XSLT for data exchange, it
then requests data to a server in an asynchronous way using XMLHttp request, it puts it all
together and presents it to the user through Java Script.
Anchor
This is an abbreviation to refers to the internal links within a web page. A link anchor never
change the webpage but will link to a different part of the same document.
Antialiasing
Anti-aliasing is a process enabling for diminishing jaggies - stairstep-like lines that should be
smooth. Jaggies occur because the output device, the monitor or printer, doesn't have a high
enough resolution to represent a smooth line. Anti-aliasing reduces the prominence of jaggies by
surrounding the stairsteps with intermediate shades of gray or color. Although this reduces the
jagged appearance of the lines, it also makes them fuzzier.
Another method for reducing jaggies is called smoothing, in which the printer changes the size
and horizontal alignment of dots to make curves smoother.
Use anti-aliasing on GIF images with rounded edges and on large font sizes (14px or larger). Be sure to check your images and look <br />for fuzziness after you antialias the edges. I recommend that you don't use anti-aliasing at all unless the pixel "stairstepping" is <br />very obvious in your image. Displays have very high resolutions and so should make the pixelation that antialiasing is trying to <br />mitigate less apparent. Never use font smoothing or anti-aliasing on fonts smaller than 10px. This makes them even more difficult to <br />read.
Applet
An Applet is a component from an application which is executed in another programm context,
such as the web browser. Applets examples are Java applets, and Flash animations.
Attribute
It is a part of an element which adds information to that element.
Aural
It is related to the hearing. Aural in the web pages is referring to the style aural pages used by
the web deployers to make their web-pages aural to those users with visual impairment.
Azimuth
Angle between the north vector and the perpendicular projection of the sound down onto the
centre. When the azimuth is adjusted for different sounds, it creates a natural way to separate
those sounds such as stereo audio or 5 speakers, locating every sound in a different space.
