  SS1 INFORMATION PROCESSING AND TRANSMISSION  Information processing is the change of information in any manner detectable by an observer. As such, it is a process which describes everything which happens (changes) in the universe, from the falling of a rock (a change in position) to the printing of a text file from a digital computer system. Information represented digitally in two-state, or binary, form is often referred to as digital information. Modern information systems are characterized by extensive metamorphoses of analog and digital information. - Collation of information - Organization of information - Analysis of information - Interpretation of information Collation is the assembly of written information into a standard order. Advantages of sorted list include: One can easily find the first n elements and the last n elements One can easily search for an element, and conclude whether it is in the list. One can easily search for an elements in a given range. In
