Logic Programming Languages C10.1.1. Prolog Suppose we know the average speeds of several automobiles on a particular racetrack and the amount of time they are on the track. This basic information can be coded as facts, and the relationship between speed, time, and distance can be written as a rule.
Queries can request the distance traveled by a particular car.
Concurrent Programming C10.2.1. Only statement and unit levels involve language issues. The execution can be restarted later from the point where it relinquished control. Each processor has its own local memory. One processor is used as the controller for the other processors.
