Service

Any on-line activity performed for others and which is generally available.

By ``generally available'' we mean that the business in general is the service, not a single transaction or a series of transactions taking place under a single agreement, and it should be available at any time from any location.

A service includes activities such as Web-based mail, credit card authorisation or news headlines. But a service can also include access to resources such as disk space, memory, CPU time, bandwidth and IP addresses.
