WHAT IS CPU IN COMPUTER:- So you're buying a replacement computer in an electronics store and you're trying to form sense of the technical specifications one computer that appears pretty cool features a 64-bit quad-core Intel i7 3.5 gigahertz processor sounds impressive but what does it really mean the last computer you purchased a couple of years ago had a sticker thereon that said Pentium 4 but you do not remember the small print the pc was getting kind of slow but why would you would like a 64-bit quad-core why exactly is that this better than the processor in your old computer to know what the specifications mean we first need to check out how the processor is meant and the way it functions the central processing unit CPU of a computer may be a piece of hardware that carries out the instructions of a computer virus it performs the essential arithmetic 'el logical and input/output operations of a computing system the CPU is just like the brains of the pc every instruction regardless of how simple has got to undergo the CPU so for instance you press the letter K on your keyboard and it appears on the screen the CPU of your computer is what makes this possible the CPU is usually also mentioned because the central processing unit unit or processor for brief so once you are watching the specifications of a computer at your local electronics store it typically refers to the CPU because the processor once we start to seem at the varied components of a CPU and the way they function remember that are often. This is often all about speed once we use a computer we would like the instructions to be administered in no time because the instructions become more complicated for instance creating a 3d animation or editing a video file we demand more from the CPU thus the technological advances we've seen in processor technology have largely been driven by the necessity for speed a typical CPU features a number of components the primary is that the arithmetic logic unit ALU which performs simple arithmetic and logical operations is that the control unit CU which manages the varied components of the pc it reads and interprets instructions from memory and transforms them into a series of signals to activate other parts of the pc the control unit calls upon the arithmetic logic unit to perform the required calculations third is that the cache which is high speed memory where instructions can be copied to and retrieved early CPUs consisted of the many separate components but since the 1970s they need been constructed as one integrated unit called a microprocessor intrinsically a CPU may be a specific sort of microprocessor the individual components of a CPU became so integrated that you simply can't even recognize them from the surface this CPU is about 2 inches by 2 inches in size CPUs are located on the motherboard motherboards have a socket for this which is restricted for a particular sort of processor a CPU gets extremely popular and thus needs its own cooling system within the sort of a heatsink and/or fan the ALU is where the calculations occur but how do these calculations actually get administered to a computer the planet consists of zeros and ones inside a processor we will store zeros and ones using transistors these are microscopic switches that control the flow of electricity counting on whether the switch is on or off therefore the transistor contains binary information a 1 if a current passes through and a 0 if a current doesn't undergo transistors are located on a really thin slice of silicon one chip can contain thousands of transistors one CPU contains an outsized number of chips combined these only cover a few sq in approximately during a modern CPU however that sq in can hold several hundred million transistors the very latest high-end CPUs have over 1 billion calculations are performed by signals turning on or off different combination
