Example : Finding a patient's record in a doctor's surgery can be done in seconds on a computerised database system, whereas it would take a receptionist some minutes to locate a folder in a paper filing system.

a network will arrive at its destination anywhere in the world in just a
Example : A computer user can place an order for an item on an Internet website and it will be received immediately - posting an order in the mail would take a day or two to arrive.
