Operating Systems : Network

Operating systems that are used on computers connected to networks usually have to carry out some additional tasks. Probably the most important of these is managing system security. Important aspects of systems security that an operating system might manage are :

• Making a user log on with a user name and password before a computer can be used.

• Allow a user on one computer to access files stored on another computer (e.g. a server).

• Controlling who has access to which files.

• Keeping a log of all of the files that a user changes.

• Automatically backing up important files.
