There is a multitude of different types of servers. File servers are equipped with large hard drives that are used to share files and information, as well as whole applications. The file-server software allows shared access to specific segments of the data files under controlled conditions. Print servers accept print jobs sent by anyone on the network. These servers are equipped with spooling software (saving data to disk until the printer is ready to accept it) that is vital in the situations where many requests can pour in at the same time. Network Operating Systems package requests from ...

- ... demand for safety has led to a boom industry in data security. Security measures range from user Ids and passwords to thumbprint, voiceprint or retinal scan technologies. Another approach is public key encryption, used in software packages such as Entrust. An information system girded with firewalls and gates, broken vertically into compartments and horizontally by access privileges, where suspicion is the norm and nothing can be trusted, will probably reduce the ... disk. Web browsers can also download running code, some of it possibly malign. Distributing objects over global networks without a good way to authenticate them leads to similar risks. Crackers have also succeeded in tainting software sold by brand-name manufacturers. A clutch of companies offer antiviral programs, capable of detecting viruses before they have the chance to spread. Such programs find the majority of viruses but virus detection is likely ...
