Because the future price of a stock at time t cannot be predicted with certainty, we model it as a random variable, denoted here by S(t). Since random variables are characterised by their distribution functions it is useful to have a notation to express this concept.

Widespread availability of network access and networked information systems has created a high demand for new generation multi-protocol aware information browsing and presentation tools. In order to support eecient programming and operation for such tools, new networking languages will need to be employed. This study attempts to identify requirements for these networking languages and their env...
