Information systems which manage data storage, transformation and communications have changed significantly during the last 20 years from localised operations to systems which coordinate components over global networks such as the Internet and where many different systems transmit information far beyond the "local" boundries to anywhere in the world with appropriate access technology.
Where does information go?
The evolution of the dimension of networks has changed the concept of where information goes (e.g. to a storage device or down a network) and its state, determined as to whether it is going to a dialogue, storage device, printer, as a formatted packet going down a network or any other intermediate or final form.
The merging of functions around digital plastic
This increasing array of forms in which data can be used and output has created an amazing plasticity reflected in the most obvious form in multi-media as image, sound and text. This has changed the simple concept of destination of data (which was normally a storage device as a discrete systems component) to a complex dynamic which can be analysed through locational-state theory and practice.
Costs and access
During the last 35 years there have been a significant falls in the cost of systems components measured in terms of a operational capacity. The ability to have many online users sharing central server resources has created significant advantages in terms of cost of investment per user. This advantage has been further extended through the provision of shared logical and processing capabilities (scripts) running off central servers.
