Computer graphics is the use of computers to generate information in visual images, either on a monitor or via a printer or plotter.

There are two types of computer graphics: raster and vector. The raster graphic is composed of pixels while the vector graphic is composed of drawing paths. The raster images are more commonly called bitmap images.

In computer graphics editing, an image editing software is a program or collection of programs that enable a person to create and edit visual images on a computer.

Many graphic software applications offer a variety of features for creating and editing pictures on the computer. Even multimedia authoring and word processing programs include some simple features for drawing on the computer. Most graphics programs have the capacity to import and export one or more graphics file formats.

Different kinds of image editing programs offer different kinds of graphic features at different levels of sophistication, but they tend to specialize in one or the other.

Word processors, like MS Word, offer a handful of simple drawing functions. They aren’t that powerful, but if all you need is a basic illustration made up of simple shapes to clarify a point, they are fine. Some programs specialize in graphics creation. Some are all-purpose programs, which offer both drawing and painting functions. Some programs are targeted specifically at children; it has a simplified interface and lacks the sophisticated functions a professional artist might want.

Other programs, like Adobe Photoshop, specialize in painting functions, even though they may include drawing functions as well. Painter is a paint-oriented program that offers highly sophisticated, “natural media” functions that approximate the effects of watercolors or drawing with charcoal on textured paper.

Other graphics programs, such as Adobe Illustrator, specialize in drawing for professional artists and designers; AutoCAD is used mainly for technical and engineering drawing.

Page layout, presentation, multimedia authoring and Web development programs usually contain a variety for graphics functions ranging from the simple to the complex, but their main purpose is composition, not image creation or editing. They allow you to create or import text and graphics and, perhaps, sound, animation and video.

Through this, different websites and search engines bring out color in the internet. This helps in attracting many internet surfers and would increase link popularity. No wonder Google counts more than 1 Trillion Web URLs, this may be caused by continuing graphical advancements.

In a discovery that would probably send the Dr. Evil character of the “Austin Powers” movies into cardiac arrest, Google recently detected more than a trillion unique URLs on the Web.

This milestone awed Google search engineers, who are seeing the Web growing by several billion individual pages every day, company official wrote in a blog post.

In addition to announcing this finding, Google took the opportunity to promote the scope and magnitude of its index. “We don’t index every one of those trillion pages- many of them are similar to each other, or represent auto-generated content… that isn’t very useful to searchers. However, we are proud to have the most comprehensive index of any search engine, and our goal always has been to index all the world’s data,” wrote Jesse Alpert and Nissan Hajaj, software engineers in Google Web Search Infrastructure Team.

It had been a while using Google had made public pronouncements about the size of its index, a topic that routinely generated controversy and counterclaims among the major search engine player’s years ago.

Those days of index size envy ended when it became clear that most people rarely scan more than two pages of Web results. In other words, what matters is delivering 10 or 20 really relevant Web links, or even better, a direct factual answer, because few people will wade through 5,000 results to find the desired information.

It will be interesting to see if this announcement from Google, posted on its main official blog, will trigger a round of actions from rivals like Yahoo, Microsoft and Ask.com.

In the meantime, Google also disclosed interesting information about how and with what frequency it analyzed these links. “Today, Google downloads the web continuously, collecting updated page information and re-processing the entire web link graph several times per day. This graph of one trillion URLs is similar to a map made up of one trillion intersections. So multiple times every day, we do the computational equivalent of fully exploring every intersection,” the officials wrote.

There are many ways to attract people into websites one of the easiest and more effective ways is through a creative and effective design. By design we just do not say good looking artsy web pages. A good designs includes the aesthetics, functionality, speed and friendliness of a site. There are great sites in terms of artistry and animation but are absolutely a labyrinth to explore therefore absolutely useless.

Another strategy employed by web developers is though search engine optimization and linkages. Basically, these means getting more links to the site and making it very visible to “web crawlers” allowing the site to increase in terms of relevance. As most people look for information in the Internet through web engines, mastering this strategy makes your website appear on top of search results for some key words, increasing the likelihood that people will get into your site.

One of the most popular website genre in the Internet is the news websites. Most people in the Internet look for information and what is better information that learning the recent events of the day. News websites like www.cnn.com or ww.bbc.com are a good test case in determining how websites are being appreciated and used by the public and how the people behind these sites listen and adapt to the needs and trends of their audience. The numbers speak for themselves, news websites are the most revenue-generating in the Internet, therefore, they must be doing something right.

A survey by the Poynter Institute study indicated that people go to news websites expecting several things – the site can update quickly (therefore breaking news will be posted fast and new details updated every moment), the site is customizable (people can choose what news they want to read) and there is a feedback mechanism (forum, letter to the editor functions, etc).

By reading through the results of the survey indicated that people actually do not go for the looks of the site, but rather on its functionality. Sure, photos, graphics even embed music will add to the overall experience of an Internet surfer, but as what the Poynter study shows, people are looking for more than just the surface. They dig far deeper than just the first page of the website. People look for usability and ease.

At the core of it all, however, is the people’s need for content. Websites that know who they are, what information they contain and what audience they are trying to attract are the most successful. As wide as the demographics of people in the Internet are, online buffs also tend to converge in common interests and ideals. This can be achieved only by great content. All other things are secondary.

Great content produce traffic. Traffic brings relevance and more traffic. Significant traffic brings in the revenues.
