Essential Compression Issues: Storage, Speed and Keeping Up with Moore and Parkinson
In the big picture, what makes file compression so important? The discussion hinges on two "laws" of the digital media world. The first is Moore's Law, which indicates that computers roughly double in speed every 18 months. The second is Parkinson's Law of Data, which submits that computer data expands to fill storage space.
The need for compression is demonstrated at the intersection of these two laws. The increase in speed generates more data; data that will fill the available storage space. Compression is the answer to a digital world that creates ever-increasing amounts of data.
Benefits of Compression
Compression answers the need for more efficient storage of digital information. Compression makes it possible for digital media files to optimize the increasing speed of computer systems. Compression reduces the time it takes for backups of crucial corporate data. Compression maximizes the potential of the Internet, internal business networks, and wireless devices for individuals and businesses alike. Without compression, digital media would simply fill up the available space for storage - and bandwidth for transmission - of electronic files far too quickly.
