Computer Architecture Questions
The main difference between multiprocessors and multicomputers lies in their architecture and communication mechanisms.
Multiprocessors refer to a system where multiple processors or central processing units (CPUs) are connected and share a common memory. These processors work together to execute tasks and share resources, such as memory and I/O devices. In a multiprocessor system, all processors have access to the same memory and can communicate with each other through shared memory.
On the other hand, multicomputers are composed of multiple independent computers or nodes, each with its own memory and I/O devices. These nodes are connected through a network, allowing them to communicate and share information. In a multicomputer system, each node operates independently and has its own memory space. Communication between nodes is typically achieved through message passing, where messages are sent between nodes over the network.
In summary, the key difference is that multiprocessors have shared memory and processors work together on a common set of tasks, while multicomputers have distributed memory and independent nodes that communicate through message passing.
