Multiprocessor vs. Multicomputer — What's the Difference?
By Tayyaba Rehman — Updated on September 20, 2023
A multiprocessor system involves multiple CPUs sharing memory and operating within a single computer system. A multicomputer system comprises multiple independent computers interconnected by a network, each with its own memory and CPU.

Key Differences
A multiprocessor system consists of multiple CPUs or processors that are incorporated into a single computer system. These CPUs share system resources such as memory and I/O devices. A multicomputer system, on the other hand, involves multiple independent computers, each having its own CPU and memory, connected through a network.
Multiprocessor systems generally offer advantages in terms of performance due to the shared system resources. Multicomputer systems are more flexible in scaling since they involve multiple independent computers connected through networking.
In multiprocessor systems, data consistency is often easier to maintain because all processors work on a shared memory. In multicomputer systems, data consistency can be more challenging as data is dispersed across different machines.
Lastly, multiprocessor systems tend to be more costly to set up due to the need for specialized hardware that can accommodate multiple CPUs. Multicomputer systems can be more cost-effective because they can be assembled using off-the-shelf hardware.
