The motherboard connects and controls all of the essential elements of a computer or digital device the keyboard, the cpu, the video card, memory and the hard disk drive. Cpu stands for central processing unit overall a personal computer can be divided into the following major parts from point of view of functions. The central processing unit for example, a cpu-demanding video editing program that functions best on multiple cpu cores is going to work better on a multicore processor with low clock speeds than it would on a single-core cpu with high clock speeds. Start studying the purpose and function of the cpu learn vocabulary, terms, and more with flashcards, games, and other study tools. Computing acronyms are confusing what is a cpu anyway and do i need a quad or dual-core processor how about amd, or intel we're here to help explain the difference. The function of the cpu (centeral processing unit) is to perform operations which make your computer run.

This intrinsic stores the supported features and cpu information returned by the cpuid instruction in cpuinfo, an array of four 32-bit integers that is filled with the values of the eax, ebx, ecx, and edx registers (in that order)the information returned has a different meaning depending on the value passed as the function_id parameter. Total cpu (%) the percentage of the app's cpu activity in the selected time range that was used by calls to the function and the functions called by the function.
