松耦合和紧耦合多处理器系统之间的区别

松耦合多处理器系统：
它是一种多处理系统，其中，存在分布式内存而不是共享内存。在松耦合的多处理器系统中，数据速率较低，而不是紧密耦合的多处理器系统。在松耦合的多处理器系统中，模块通过MTS(消息传输系统)网络连接。

紧密耦合多处理器系统：
这是一种多处理系统，其中有共享内存。在紧密耦合的多处理器系统中，数据速率较高，而不是松散耦合的多处理器系统。在紧密耦合的多处理器系统中，模块通过PMIN，IOPIN和ISIN网络连接。

让我们研究一下松耦合和紧密耦合的多处理器系统之间的区别：

S.NO	Loosely Coupled	Tightly Coupled
1.	There is distributed memory in loosely coupled multiprocessor system.	There is shared memory, in tightly coupled multiprocessor system.
2.	Loosely Coupled Multiprocessor System has low data rate.	Tightly coupled multiprocessor system has high data rate.
3.	The cost of loosely coupled multiprocessor system is less.	Tightly coupled multiprocessor system is more costly.
4.	In loosely coupled multiprocessor system, modules are connected through Message transfer system network.	While there is PMIN, IOPIN and ISIN networks.
5.	In loosely coupled multiprocessor, Memory conflicts don’t take place.	While tightly coupled multiprocessor system have memory conflicts.
6.	Loosely Coupled Multiprocessor system has low degree of interaction between tasks.	Tightly Coupled multiprocessor system has high degree of interaction between tasks.
7.	In loosely coupled multiprocessor, there is direct connection between processor and I/O devices.	While in tightly coupled multiprocessor, IOPIN helps connection between processor and I/O devices.
8.	Applications of loosely coupled multiprocessor are in distributed computing systems.	Applications of tightly coupled multiprocessor are in parallel processing systems.
