Over the past several hundred years, society has experienced dramatic improvements in how information systems are used to create, store, and evaluate data. Modern society depends heavily on information systems to help improve efficiency in both daily routines and work related tasks. A few of the most prominent forms of these types of systems include things like smart phones, tablet computers, and the internet.
Nearly every household, in developed countries, has between three and five computers operating at any given time. These computers link to a vast network of hardware and software that supports a tremendous amount of virtual collaboration. The business community has also adopted highly complex information systems that occupy entire warehouses and dramatically improve the way operations are carried out. While many people are now born into a society that understands computers well, it was not that long ago when complex computer systems were a fantasy.
