File compression is a technology thatallows the fast delivery of very large files. In practice, you can think of itin much the same terms as you might think of sending a letter through the mail.There will be several different elements involved in your getting the letterdelivered.For the purposes of example, wellconcentrate on 4 elements: the text of your letter; the paper on which itswritten; the envelope in which its contained; and the delivery service thatgets it from your hands to the recipient.The text of your letter is the equivalentof the raw information in your file. When your file is compressed, a complexmathematical algorithm allows the computer to eliminate some of the informationfrom the file, which can be later reconstructed during decompression.As a simple example, say your letterstarted with the phrase: Hi, John. How are you? If you were to compress thatstatement, it might read: H, Jn. Hw r u? Even though it doesnt contain allthe original letters, youd know what it said. The algorithms used in filecompression work in a similar fashion.The paper on which your letter is writtenis the equivalent of your file format. In this case, your format is paper.Other example formats would be a piece of cardboard or a clay tablet. When youcompress a digital file, youll find that some formats fit in the envelopebetter than others.The paper, for example, will be easy tofold up and put in an envelope. The clay tablet, of course, wont fold at all.In a similar fashion, text files compress very well and image files verypoorly. Format matters.The final step is delivery. Yourcompressed, folded and enveloped letter is ready to go, but you need to get itto the right address.Usenet technologies, such as NZB, allow forthis to be done easily. These technologies allow you to find files very easily,and to post them just as easily. Much as your address does, NZB technologyallows you to identify where something is and to find it amidst thousands ofpossible locations with ease and accuracy.Because the files are compressed, they takea short time to download. The combination of compression and high-bandwidthservices make the Usenet one of the best places for file sharing on todaysInternet.
