并行计算:
在并行计算中,多个处理器同时执行分配给它们的多个任务。并行系统中的内存可以是共享的,也可以是分布式的。并行计算提供并发性并节省时间和金钱。

分布式计算:
在分布式计算中,我们有多个自治计算机,在用户看来它们是单个系统。在分布式系统中,没有共享内存,计算机之间通过消息传递进行通信。在分布式计算中,单个任务被分配到不同的计算机上。

并行计算和分布式计算的区别:

S.NO Parallel Computing Distributed Computing
1. Many operations are performed simultaneously System components are located at different locations
2. Single computer is required Uses multiple computers
3. Multiple processors perform multiple operations Multiple computers perform multiple operations
4. It may have shared or distributed memory It have only distributed memory
5. Processors communicate with each other through bus Computer communicate with each other through message passing. 6. Improves the system performance Improves system scalability, fault tolerance and resource sharing capabilities
