networked computers are just normal personal computers connect together businesses usually connect them in a network to fill business needs e.g. to provide Internet or to monitor productivity... so to answer you question most big business will have this and a fair few smaller business will have this setup or will have. The limitations is that in companies the regular users can not add programs and they do not have admin control, so they need their own computers to do some functions and the networked computers are highly monitered, so they may want privacy.
It is unknown if computers will replace books in the future.
An Ad Hoc network is a term used to discribe a network link directly between two computers using their network interfaces (wireless or wired). This would be an alternative to a more usual network setup where two or more computers would link up through a central network switch or hub. Normally Ad Hoc networks are created as a temp measure to achive a particular task like printing over Wireless or transfering files from one PC to another. An Ad Hoc network wold not normally take the place of any other network already configured on a PC.
