What is Compression?
Compression is the process of pressing or squeezing something so that it becomes smaller, the reduction of the volume or mass of something by applying pressure, or the state of having been treated in this way
Compression is a way of making something big small while still retaining its value. Maps, Initials, shorthand, small models, making data into a form that minimizes the space required to store or transmit it are all forms of compression. Algebra, numbers and written languages are also forms of compression or ways of shortening the writing time for pictographs.
