Analogy to Client/Server Application
A simple analogy to the client/server application is the
time-and-temperature service that is provided by the local telephone
company. To acquire the time and temperature, you:
look up time and temperature in the telephone directory
dial the number
receive an announcement of the time and local temperature
hang up the telephone
The following flow chart shows a client/server analogy to the
time-and-temperature operation.
