Answer:
In computers, multiple processes can be processed at the same time in parallel. The type of computing is called <u>Parallelism. </u>It is the type of computing in which a big task also may subdivided into smaller portions and then execute them in parallel. There are Five types of parallelism.
<u>A. Instruction Level Parallelism</u>
A type of computing in which multiple instruction of the same program can be run at the same time in parallel. In this type of parallel computing, it is measured that how many instruction of the program can be executed simultaneously.
<u>B - Data Level Parallelism/SIMD</u>
The type of computing in which same data can be used in multiple processes at the same time. The same data that is used in all program or instructions that are used in parallel operations can use at the same time.
<u>C - Thread Level Parallelism</u>
In this type of computing an application can access multiple threads at the same time.
<em>Threads are the small instructions of program that are independent from program but necessary to run the program. </em>
<em />
<u>D - Request Level Parallelism</u>
In this type of computing multiple request from end users can be processed simultaneously.
<em>Request is the task that is needed to be processed by user or run time.</em>
<em></em>
E - Data Level Parallelism/MapReduce
In this type of computing multiple processes that are independent from each other are processed at the same time. In this type order of the operations of instruction doesn't matter.
