Graphic images on your computer come in two different forms, raster images and vector images. Raster images are made by programs such as Photoshop and Corel Photopaint. Vector images are produced by Adobe Illustrator, Freehand, and CorelDraw. While the results from these different programs can look similar, the ways in which they are made are very different.
Raster images are made up of millions of individual squares, or pixels, of various colors. The more pixels you have, the better the image will look. The number of pixels, or resolution, is usually expressed in dots per inch (dpi). Images on the Web are shown at 72 dpi. A high-resolution image would run 300 dpi or higher. Some types of printing can get into the 1600 dpi range. Much like a mosaic, a raster image can look smooth from a distance but as you zoom in closer you can see the individual pixels.
A vector image is drawn from mathematical formulas for lines and curves and is redrawn each time you zoom in for a closer look. The quality of the image stays the same regardless of the level of magnification. Vector files, since they are formulas instead of information on millions of individual pixels, tend to use less memory than raster files.
The edge of a circle, rendered as a raster image, may look smooth initially, but eventually as you zoom in you will see a jagged stairstep edge of the individual square pixels that make up the image. A lower resolution image will look jagged or pixellated much sooner than a high resolution image. A circle's edge in vector form will always be smooth no matter how close you zoom in since it is recalculated each time you change the view.
Raster based programs are best at working with photo-realistic images and make subtle (or bold) changes in color, shadow and texture. Vector based programs excel at easy control of edges and tend to produce a more graphic style of art. Regardless of the type of image, higher resolution is always better for producing a good result. While your image may be vector or raster, or even a combination of the two, the Art Staff at ExpertShirt.com will work hard to translate it into the best textile printing possible.

Day Trading Computer
Day Trading Computer
by: Dan Alvarez
Computers are so cheap nowadays that almost any new computer will be sufficient for day trading. Below I will highlight the basic components that you need for your day trading system: hardware, software, Internet connection, and system protection.
Hardware for day trading
This is a typical trading computer setup with two monitors connected to the same computer. This allows the day trader to expand the trading screen across both monitors as if was one big rectangular monitor. Thus, more graphs and other market data can be observed by the day trader at the same time. Even though I do not have a Ph.D. in computers, I have used and helped people set up computers for day trading, and know other people that use computers for the same thing. Below I have provided the minimum general specifications for day traders followed by the preferred specifications (in parentheses):

Learning Math and Dosage Calculations Using a Computer Program
by: Sue Peters
Introduction
In nursing particularly, absolute competence is a must as patients? welfare is directly connected to any action or decision that you take. Give the wrong dosage or medication and a patient can be killed. Naturally, this can have devastating consequences so it is absolutely crucial that you take all the precautions in keeping up to date and maintaining your skills.
Dosage calculations are no exception and the reported cases of medication errors on an annual basis is very high. Despite this, many nurses absolutely fear performing calculations of any sort! Why is this? Most likely because the calculations involve a knowledge of maths and maths can be a daunting task - especially if it has been a long time since you studied at school or university.
The reality of the situation however, is not as bleak as it often appears to nurses. To perform dosage...

More Memory (RAM)
If your computer has less then 256 MB of memory you may want to consider adding more. If you don?t know how much memory you have: right click my computer, go to properties and look towards the bottom of the dialog box.
Memory is where the computer stores open files or programs in order to give the processor quick access.
To put it simply more memory means more speed and stability.
You can buy memory online or visit your local Best Buy where they can install it for you if you don?t feel comfortable doing it yourself.

Eye Strain Caused By Your Computer
Eye Strain Caused By Your Computer
by: Hege Crowton
Visual problems like eyes strain may result from overusing the muscles of your eyes. If not careful, eye strain will occur in any eye muscle held in one position for a long period of time.
These eye straining activities are as follows: reading, watching television, or staring at the computer.
People with occupations that require lots of staring such as dressmaking, designers, or computer engineers are prone to developing eye strain. Even people who do a lot of reading is prone to developing eye strain like medical students, lawyers, scientists, and researchers.
The muscles of your inner eye tightens and irritates your eyes, making you feel very uncomfortable, resulting to eye strain. A five-minute break from time to time is very good to your eyes.
