Introduction To Information Processes And Data

information processes
-collecting the process by which data is entered into or captured by a computer system, including: deciding what data is required how it is sourced how it is encoded for entry into the system
-organising the process by which data is structured into a form appropriate for the use of other information processes such as the format in which data will be represented
-analysing the process by which data is interpreted, transforming it into information
-storing and retrieving the process by which data and information is saved and accessed later
-processing a procedure that manipulates data and information
-transmitting and receiving the process that sends and receives data and information within and beyond information systems
-displaying the process that controls the format of information presented to the participant or user

the nature of data and information
-data the input to an information system
-data representation the different types of media, namely: images audio video text numbers
-information the output which has been processed by an information system for human understanding
-the generation of information from data via the information processes
-how information from one information system can be data for another information system

reasons for digital data representation
-the need for quality data, including: accuracy timeliness accessibility
-current data digitising trends, for example: newspapers on the Internet telephone system video on DVD facsimile media retrieval management
