If your computer has 2 processors, it can then run two tasks at the same time. This is called
A
Multiprogramming
B
Multitasking
C
Multiprocessing
D
None of the above
Explanation: 

Detailed explanation-1: -Multiprocessing is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them.

Detailed explanation-2: -In multiprocessing system, a computer uses more than one CPU at a tme. Multitasking-Multitasking is the ability of an operating system to execute more than one task simultaneously on single processor machine, these multiple tasks share common resources such as CPU and memory.

Detailed explanation-3: -Multiprocessing is typically carried out by two or more microprocessors, each of which is in effect a central processing unit (CPU) on a single tiny chip. Supercomputers typically combine millions of such microprocessors to interpret and execute instructions.

Detailed explanation-4: -Multitasking: When a single resource is used to process multiple tasks then it is multitasking. Multithreading: It is an extended form of multitasking. Multiprocessing: When more than one processing unit is used by a single computer then it is called multiprocessing.

Detailed explanation-5: -MULTIPROCESSING:simply means using two or more processors within a computer or having two or more cores within a single processor to execute more that more process at simultaneously. PARALLEL PROCESSING:is the execution of one job by dividing it across different computer/processors. Save this answer.
