Parallel computing and distributed computing are ways of exploiting parallelism in computing to achieve higher performance. Multiple processing elements are used to solve a problem, either to have it done faster or to have a larger size problem been solved. To state simply, if the processing elements share the memory, it is called parallel computing, other wise it is called distributed computing. Some have opinion that distributed computing is a special form of parallel computing.
supercomputers allows both parallel and distributed computing
"Distributed" or "grid" computing in general is a special type of parallel computing, it is advanced in the means of using distributed computing.
In the most simple form = Parallel Computing is a method where several individual (autonomous) systems (CPU's) work in tandem to resolve a common computing workload. Distributed Computing is where several dis-associated systems are working seperatly to resolve a multi-faceted computing workload. An example of Parallel computing would be two servers that share the workload of routing mail, managing connections to an accounting system or database, solving a mathematical problem, ect... Distributed Computing would be more like the SETI Program, where each client works a separate "chunk" of information, and returns the completed package to a centralized resource that's responsible for managing the overall workload. If you think of ten men pulling on a rope to lift a load, that is parallel computing. If ten men have ten ropes and are lifting ten different loads from one place to consolidate at another place, that would be distributed computing. In Parallel Computing all processors have access to a shared memory. In distributed computing, each processor has its own private memory

Serial computing is executing a task on one computer. Distributed computing is executing a task on multiple computers at the same time.
well the main difference is that in a parallel system there is multiple computing units (cpu) working in one node(they share memory ,attached devices , storage...) to accomplish a computing goal in a clustered there is multiple nodes each has its own resources running its own copy of os (usually connected via lan) to accomplish a computing goal
HIGH AVAILABILITY provided by Fault Tolerant Computing Systems & Networks which might be geographically distributed and thus overcomes Single Point of Failurein mission critical applications is the main goal of Distributed Computing.
Grid Computing and Distributed Systems
clustered system: systems having many computers with shared storage and linked by a lan or network.distributed system:systems having many computers connected by a network and there is no shared storage.Distributed computing is computing done on computers connected by a network. Clusters are one type of distributed computing. MPPs are another. Grid computing is a third.
The definition of parallel computing is the processing of data many bits at a time as opposed to serial computing which is the processing of data one bit at a time.
