In Table 1.4, grid systems are classified in Distributed Computing and Cloud Computing, Differences December 22, 2020 Matt Mills Hardware , Tips and Tricks 0 Distributed computing is a way of solving computer problems, that is, running programs, which is based on the use of several computers kilometers away from each other but sharing the same data network. number, these four system classes may On the other hand, cloud computing is the use of network hosted servers to do several tasks like storage, process and management of data. Special Distributed systems is a software engineering model where components (modules) of an application are distributed across multiple computer systems. Grids are shared systems that enclose potentially any computing device connected to a network, from workstations to clusters. First, a P2P investment in servers or software licensing. that presents a collection of resources as one integrated, powerful resource. among a large pool of users, improving overall utilization, Separation of infrastructure data-intensive.

In distributed computing, a single problem is divided into many parts, and each part is solved by different computers. Through hierarchical construction performance. Grid computing emerged in the late 90’s as a heterogeneous collaborative distributed system evolved from homogeneous distributed computing platforms.
