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.
