Laughing Til You Cry

By Herbert Reich

Any media which is stored in electronic form is known as digital media. Unlike analogue media (any information which exists in physical form, such as books, paintings and so on), digital media is information which can be stored and displayed or listened to on a computer. This media is stored in binary form (a digital format consisting of ones and zeroes which your computer can interpret) and can then be translated by your computer and presented to you in a form intelligible to human beings - text, images and audio.

Digital media is all around us now. Most of us use computers on a daily basis and of course, any information which you view on a computer is, by definition digital media. The internet is nothing more than a collection of digital media. E cards are one popular type of digital media - an E card may consist of images, text, audio and even video content. Besides video based E cards, there are also those which contain animations; these may be two or three dimensional.

These E cards are made beginning with an image in most cases. However, this can also be an animation or a video clip in the case of video E cards. Images for E cards can be taken from libraries of clip- art, photographs or created using software like Adobe Illustrator. These images are made up of pixels, each of which is represented by a bit of digital information. The more pixels in an image, the more information it represents - meaning a larger and higher resolution image on your computer screen.

An animation, whether 2D or 3D is a series of images which appear to be moving. They are made by linking together a group of images in sequence using a scripting language. These animated images are much larger than a static image. The same technique can be used to create moving text in an E card as well. Audio clips can also be incorporated into E cards to further customize them.

All together, these images text and audio files (or animations and video, if using) comprise the contents of an E card. E cards are far easier to send to your recipient than a regular card - all you need is their email address. They can't get lost in the post and you don't even need a stamp! There are thousands of different E cards out there to choose from; the most popular style are funny E cards. You can send E cards for any occasion - birthdays, holidays and more!
