A Multiprocessor is a PC framework with at least two focal handling units (CPUs) share full admittance to a typical RAM. The primary goal of utilizing a multiprocessor is to help the framework's execution speed, with different targets being adaptation to internal failure and application coordinating.
There are two sorts of multiprocessors, one is called shared memory multiprocessor and another is conveyed memory multiprocessor. In shared memory multiprocessors, every one of the CPUs shares the normal memory yet in a disseminated memory multiprocessor, each CPU has its own private memory.
Utilizations of Multiprocessor
1. As a uniprocessor, for example, single guidance, single information stream (SISD).
2. As a multiprocessor, for example, single guidance, various information stream (SIMD), which is normally utilized for vector handling.
3. Multiple series of directions in a solitary point of view, for example, various guidance, single information stream (MISD), which is utilized for portraying hyper-stringing or pipelined processors.
4. Inside a solitary framework for executing various, individual series of directions in numerous points of view, for example, different guidance, various information stream (MIMD).
Advantages of utilizing a Multiprocessor
- Improved execution.
- Different applications.
- Performing various tasks inside an application.
- High throughput and responsiveness.
- Equipment dividing between CPUs.
What is a Distributed Database System?
A dispersed data set (DDB) is an assortment of various, consistently interrelated information bases appropriated over a PC organization. A disseminated information base administration framework (D-DBMS) is the product that deals with the DDB and gives an entrance system that makes this circulation straightforward to the clients. Circulated information base framework (DDBS) = DDB + D-DBMS
Dispersed DBMS Promises
- Transparent administration of dispersed, divided, and reproduced information
- Improved unwavering quality/accessibility through appropriated exchanges
- Improved execution
- Easier and more practical framework extension
Why Distributed Systems?
- Disseminated frameworks are presently a necessity.
- Financial aspects - little PCs are extremely practical
- Asset sharing
- Sharing and printing documents at remote destinations
- Handling data in a conveyed data set
- Utilizing remote particular equipment gadgets
- Numerous applications are by their tendency disseminated
- Bank employee machines, carrier reservations, ticket buying
- Calculation speedup - To tackle the biggest or most information escalated issues, we utilize many collaborating little machines (equal programming)
- Unwavering quality

Multiprocessor and Distributed Systems
Essentially all frameworks today are dispersed here and there, e.g.: they use
- They access documents over an organization
- They access printers over an organization
- They are upheld over an organization
- They share other physical or coherent assets
- They help out others on different machines
- They get video, sound, etc.CS-3013 and CS-502, Summer 2006

Is dispersed framework multiprocessor?
In software engineering, dispersed memory alludes to a multiprocessor PC framework wherein every processor has its own private memory. Computational assignments can work on neighborhood information, and in the event that far off information are required, the computational undertaking should speak with at least one distant processor.
Multiprocessor VS Distributed
|Degree of transparency||High||Very high|
|Basic of communication||Shared memory||Message passing|
A Multiprocessor is a computer system with two or more central processing units (CPUs) share full access to a common RAM. In shared memory multiprocessors, all the CPUs shares the common memory but in a distributed memory multiprocessor, every CPU has its own private memory.
