Most computer networks are fat client networks, where each computer on the network is fully responsible for all its processing, so it has to have all the software installed on its local harddrive and enough memory and processing power to run all that software. Unfortunately, these networks are inefficient uses of resources and very costly to maintain. Fed up with managing networks which were increasingly unmanageable, today many network administrators are turning to thin client networks as a way to simplify network management and hold their costs at bay. Similar to the old dumb terminals, thin clients are only in.
