A computer system comprises a plurality of computers 1,2 and a plurality of web servers. The computers 1,2 can interact with each other via the world wide web 4. The web servers each have a respective address and software is provided for defining a notional multi-dimensional space where co-ordinates in the multi-dimensional space are representative of the server addresses. Each computer 1,2 may be provided with a browser and co-ordinates of the position of each browser in the multi-dimensional space can be derived from the address of the server computer. A browser can travel in the notational space by moving from one server address to another and if the distance exceeds a given range the browser is prevented from accessing the representative server. |
