Why cant a single computer processor execute two or more programs simultaneously?
In simple terms a single processor can only process one machine instruction at a time; it's just not possible to execute two or more instructions simultaneously and therefore not possible to execute 2 programs simultaneously. However, it's not quite as simple as that because a modern processor can have 2 or more cores, in which case it is possible to execute 2 or more instructions simultaneously. However, that's not quite the same thing as executing 2 programs simultaneously as we invariably execute far more threads of execution than we have cores available. Note that a program consists of one or more processes and a process consists of one or more threads of execution. Although it is theoretically possible to execute two threads simultaneously upon two cores, when those cores share the same processor they also share the same L2 cache and that's really only beneficial when both threads share the same process. With 2 independent processors there's a better chance of simultaneous program execution, however it's nigh on impossible to guarantee this unless the system is specifically designed for that purpose. In a multi-processing, multi-threaded environment, task-switching makes it next to impossible for any two independent programs to execute simultaneously because every thread has to yield to waiting threads.
By having many processor can execution time of the task can be made faster?
Absolutely! the more processor cores you have the more instructions the computer can handle at the same time.
What is the difference between concurrent processing and simultaneous processing. A single processor can execute two processes concurrently but not simultaneously Why?
Single processor can execute 2 process concurrently means when one is doing i/o activity at tht time another is executing.. but not possible tht both are executing cpu at same time
How is the speed of current CPUs rated?
CPU's are now are rated in Ghz which means "Billions of Cycles per Second" Essentially, the more Ghz the processor has, the faster it will execute instructions. Older computers where rated in mhz which is a million cycles per second. For example, a 2.4 ghz processor is the same as 2400 mhz CPU, or a 500 mhz CPU is the same as a .5 ghz CPU. Single core vs. Dual Core vs. quad core ect, A core is what carries out the instructions. two cores doesn't necessarily mean that the processor will have twice the ghz, but twice the power if the program can take advantage of them.
Diffirence between multiprogamming and multitasking?
Multitasking: The ability to execute more than one task at the same time is called multitasking. It involves only one CPU. Multiprogramming: The ability to execute more than one task but not simultaneously is called multiprogramming.
What is a software application program?
A Computer Program (also software, or just a program) is a sequence of instructions written to perform a specified task with a computer. A computer requires programs to function, typically executing the program's instructions in a Central Processor. The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, from which executable programs are derived enables a programmer to study and develop its algorithms.
Does 1.9GHz with AMD A4-3305M accelerated dual-core processor equal 3.0 ghz?
This doesn't really math out properly. A 1.9GHz processor is a 1.9GHz processor. It can be the EQUIVILENT of a higher clock-rate, lower instructions per cycle processor, but it isn't the same, or "equal" at different clock speeds.
What is meant by core in core 2 duo?
"Core" processor - the central or main processor core. It has actually 2 computers on one chip so it can theoretically process two computer instructions at the same time.
What are processor features?
Features of contemporary processors include a dual core and cache memory. They also have transistors for communicating information and instructions at the same time.
Why are CPUs called cores?
When CPUs first started coming out, and for many years after, they could only execute one set of instructions at a time. After awhile, interfaces were built to support having multiple CPUs running at the same time to increase the horsepower of a machine. These CPUs had distinct packaging still, but now the computer as a whole could execute a set of instructions per CPU. CPU manufacturers started placing multiple CPUs in one distinct package and also included the interface for the CPUs to talk within this package. So even though you had one product, it could execute multiple instructions at one time. Core is a marketing term to let people know the number of independent sets of instructions that a single CPU package can execute.
What is the newest computer processor storage?
A processor and storage are not the same
Is the i7 920 and the i7 920 d0 stepping the same processor?
Yes, they function with the same processor.
