The Basics and Benefits of Image Compression by Scott Heath
Thanks to technological advances and the advent of the internet, image files have become one of the most common file types to be used and shared today. But along with their convenience, image files are often large, making them difficult to store and transmit. ... Both compression types remove data from an image that isn't obvious to the viewer, but they remove that data in different ways. ... Lossy compression is most often evident in JPEG images, and removes data from an image that, again, is not obvious to the viewer.

Data Compression For All by Robert Hanania
Anyone who has seen the movie’ Honey I shrunk the kids' can imagine how useful compression can be. Compression, which has become anonymous with Zip files work off the same idea only with a (add your joke here)'slightly' different technology. You will find a lot of data compression programs in... There are a lot of data compression programs and they are not exactly alike because they use different data compression algorithms. ... Even with experienced compression users, extracting compressed files with a newer version of a data compression program may prove difficult, so programmers...

Real-World Applications of Image Compression by Scott Heath
The many benefits of image compression include less required storage space, quicker sending and receiving of images and less time lost on image viewing and loading. But where and how is image compression used today? Just as image compression has increased the efficiency of sharing and viewing... Early evidence of image compression suggests that this technique was, in the beginning, most commonly used in the printing, data storage and telecommunications industries. ... Image compression is also useful to any organization which requires the viewing and storing of images to be standardized,...

Data and MP3 Compression: Why Do We Compress? by Matthew Bredel
In the last article (Data and MP3 Compression: Understanding "Digital"), I explained what a "digital" signal is. Remember, data can be stored as raw, or "analog" signals (like cassette tapes, VHS, or records) or they may be digitized (converted into a series of 1's and 0's) which we can later... DVD data is coded in an MPEG-2 format (similiar to MP4). ... That is when compression techniques were first introduced. ... How compression works is that we take the 70MB signal (as we described above) and by using either a mathematical algorithm or map, we can organize the bits in such a way that...

Cisco CCNP / BSCI Exam Tutorial: A Guide To Ipv6 Addressing by Chris Bryant
Learning IPv6 is paramount in your efforts to pass the BSCI exam and go on to earn your CCNP, and it's going to help in your real-world networking career as well. IPv6 can be confusing at first, but it's like anything else in Cisco or networking as a whole - learn one part at a time, master the...

JPEG and GIF the Differences by Maricon Williams
JPEG and GIF image formats are both compression based formats. They are the most widely used and supported image formats for web. They take an uncompressed image such as bitmapped image and compress them to a smaller file size. A lot smaller image size is moreover the result of this conversion. ... JPEG is a lossless method of compression or in common parlance, when the program that creates a GIF squashes the original image down to ensure not to lose any data. ... The maximum compression of GIF depends on the amount of repetition there is in an image.

DivX and Movie Downloading -- What, How, and Why? by Sergio D'Alesio
Most films that are downloaded at present,are in the DivX Format,and by using this method of compression/decompression, a Movie can typically be compressed to about one tenth of its original size and downloaded without noticeable loss of quality to a users PC. ... For example,a Movie containing several Gigabytes of data can be compressed to several hundred Megabytes of data,and downloaded via the internet to a PC in about 2 hours using a typical 512kb DSL connection,this compares to about 20hrs for an uncompressed Movie!

DVD Basic Facts by Ray P
DVDs have become ubiquitous. Whenever we want to watch a movie or listen to some music we reach out for a DVD. Here are some basic facts about the DVD: What is a DVD? DVD is short of Digital Versatile Disk. A DVD-ROM closely resembles a CD or compact disk. ... While a CD commonly has a capacity of 650 megabytes, the smallest capacity DVD can store about seven times more data, or 4.38 gigabytes (GB). ... A DVD-ROM encodes data in the form of a spiraling trail of pits and lands separated by mere nanometers.

What Does TIFF, PNG Format Mean? by Paul Cris
What does TIFF format mean? .TIF stands for Tagged Image File Format. It is a file format for graphics for Macintosh and Personal Computer (PC) systems. Mosaic also supports .TIF format. .TIF is developed by Microsoft and Albus. The purpose of developing the file format is to store... Since GIF files need a patented data compression algorithm called LZW, it adds an extra expense. ... It has more compression capability. ... It is an approved file format by the World Wide Web Consortium as an alternative to GIF files.
