What does the CPU do?
The CPU, or Central Processing Unit performs the calculations andlogic functions of the computer. CPU's only perform the most basicof functions, such as adding the contents of a memory location tothe contents of a CPU "register", or comparing the contents of oneregister to the contents of another re…gister and "jump" on aspecified condition such as "equal to", "greater than" or "lessthan". CPU's are also able to initiate transfer of large blocks ofdata, read or write data to/from peripheral devices, and ingeneral, watch over system functions. Of course, this is anoversimplification of the power and function of the CPU, but itgives you an idea of what is going on. CPU's have the capacity toperform many low level functions that are enhanced when addedtogether into an application. If done correctly, the entire processis transparent to the user and all you see is a well designedapplication. The heatsink and the cpu needs a fan to cool them off ( Full Answer )
What is a CPU?
CPU (central processing unit) the central unit in a computer containing the logic circuitry that performs the instructions of a computer's programs. The CPU performs arithmetical, logical operations on data held in the computer memory - the RAM. The RAM is seen as a vector that contains instructions… and data provided by the computer programmer. The CPU relies on an "Operating system" such as Windows or MacOS for input and output of data, interaction with the user or storing information on the disk. Most of the CPUs made today are produced by Intel or AMD, and all of these use the same "instruction set" - or how the instructions are coded to the CPU. There are controversy about these CPU's first of all in the way that they "see" and address the memory, that is highly inefficient. CPU stands for the Central Processing Unit of a computer system. The CPU can deal with many millions of calculations per second. Bytes of data travel about the computer on electronic pathways, known as buses. Data from the CPU travels along these buses to other parts of the computer, telling them what to do. How quickly the CPU can deal with calculations is decided by the number of bytes that it can process at once (its bandwidth), and the number of instructions it can deal with during one second. The "clock speed" is like a metronome that determines the beat, and the instruction type will determine how many "clock cycles" are needed per instruction. Like incrementing a number held in a register to the CPU is much faster than incrementing a variable held in memory. The instructions are provided by programmers, that has coded in a formal computer language all the instructions. It will need an operating system to load instructions and show results - allow us to use the computer. You will find CPU in microprocessors used in digital watches, cameras, and cell phones that are just the same as those for "server systems" and "mainframes" for databases and websites. However faster and larger computers may have many CPU that even share the same memory, and is programmed to work together. When CPUs share the same memory, special precautions must be made to avoid interfering with one another. This requires that the cache memory held close to the CPU to improve speed, is either shared (e.g. "dual core") - or needs to be synchronised ("Scalable Coherent Interface") and brings on a new level of complexity. Or to put it really simply; the CPU is like the human brain, performing all of the calculations required to complete a program. ( Full Answer )
What is RAM and CPU?
Answer .
RAM = Random Access Memory. That's the volatile high speed memory that is used inside a computer that lets you store internal applications and data. Everything written to RAM is lost when you turn off the computer, so usually, important data is written to a long-term storage device, suc…h as a disk or "Flash Memory".\n.
\nCPU = Central Processing Unit. It is also sometimes called the ALU or Arithmetic Logic Unit. It's the part of the computer that makes decisions and causes things to happen. The CPU has built in instructions that allow it to perform some very basic tasks, such as:\n.
\nAdd the contents of register 1 to the contents of register 2 and store the results in register 2.\n.
\nIf the contents of register 1 are greater than the contents of register 2, continue execution of this program at line 101, otherwise continue execution at the next line.\n.
\nThere are many such "low level" commands that are executed by the CPU, and when these simple commands are being executed at a rate of over 1 million instructions per second, you get some pretty amazing results. ( Full Answer )
Who invented CPU?
John Vincent Atanasoff developed the ABC (Atanasoff-Berry Computer) at Iowa State University in October 1939 as in the following link. Patent dispute details: J. Presper Eckert and John Mauchly were the first to patent a digital computing device, the ENIAC. The ABC had been examined by John Mauchl…y in June 1941, and Isaac Auerbach, [6] a former student of Mauchly's, alleged that it influenced his later work on ENIAC, although Mauchly denied this (Shurkin, pg. 280-299). In 1967 Honeywell sued Sperry Rand in an attempt to break their ENIAC patents, arguing the ABC constituted prior art. The United States District Court for the District of Minnesota released its judgement on October 19, 1973, finding in Honeywell v. Sperry Rand that the ENIAC patent was a derivative of John Atanasoff's invention. The decision was not appealed. Campbell-Kelly and Aspray conclude: The extent to which Mauchly drew on Atanasoff's ideas remains unknown, and the evidence is massive and conflicting. The ABC was quite modest technology, and it was not fully implemented. At the very least we can infer that Mauchly saw the potential significance of the ABC and that this may have led him to propose a similar, electronic solution..
The case was legally resolved on October 19, 1973 when U.S. District Judge Earl R. Larson held the ENIAC patent invalid, ruling that the ENIAC derived many basic ideas from the Atanasoff-Berry Computer. Judge Larson explicitly stated, "Eckert and Mauchly did not themselves first invent the automatic electronic digital computer, but instead derived that subject matter from one Dr. John Vincent Atanasoff".

Component of CPU?
A long time ago in a land far away there really were people who used the term CPU for both the metal box that enclosed the main components of the computer and the Microprocessor that actually runs the main functions of the computer. The Central Processing Unit is the heart of the computer that used …to be called the Microprocessor and now has anything up to 8 microprocessors all working together. This multi - processor technology has enabled the computers to do what humans have been doing for centuries - the sort of multi - tasking housewives/ househusbands do every day ( Full Answer )
What is CPU used for?
For executing the instructions of a program. For this purpose CPU makes use of registers, ALU and control unit.
Which CPU is better?
One cannot ask for a comparison of products to determine the "better" one without specifying which products need be compared. So all I can assume is that your question is one of two things: 1. Which brand of CPUs is best. 2. Which CPU is best. .
AMD vs Intel .
AMD and Intel are the market …leaders in making CPUs. Simply put, Intel processors tend to have better performance and produce less heat, while AMD processors tend to be less expensive. .
The best processor you can get .
The question of which CPU itself is best is very difficult, depending on what aspects you are looking at. According to cpubenchmark.net, the Intel Xeon X5472, a dual core processor at 3 GHz, performs the best of any CPU tested. However, this processor is extremely expensive at about $1500 USD. An AMD processor down the line, the Athlon FX-74, ranks in about a third of the Xeon, yet its price is still over $300. There is an Intel Core 2 Duo E8400, as well, which ranks below the AMD (but still very highly) at a more reasonable price of a little under $200. Lower still, the Intel Pentium E2220 is undder $100. For even less expensive CPUs, AMD processors may still bring a high GHz level (yet with other slower and hotter-running factors). For example, the Amd AM2 U-atx 8XAGP motherboard/cpu combo is just $50. ( Full Answer )

How does a CPU work?
This is actually too complicated to fully explain. Depending on what the CPU is doing, it can work many different ways. Here is an overall sum: Information travels to its core processing center with small circuits and whatnot in the form of 1's and 0's (also known as the Binary Code). The Binary… Code is the language to the computer as English is to us, so it is necessary that the information is in Binary. As this information is sent to the core processing center, it decodes the Binary stream sent to it to display graphics, pixels, and other information in text and pictures of what we see on the monitor, and this happens just as fast as we interpret what someone is saying to us in English.

What is in a CPU?
A computer contains memory, input devices, output devices and a CPU , or C entral P rocessing U nit. The CPU is the bit that executes the program. The program is a set of instructions written by a human. The CPU reads, interprets and carries out those instructions. It is truly the heart of the… computer. The components of a computer system can be combined and permuted almost without limit. There is really just one limit; if the CPU is removed then it's not a computer anymore. Without the CPU there is nothing to send to the printer, nothing to read what is being typed on the keyboard, nothing to carry out the instructions in the program or even to know what the instructions were. What is in a CPU is quite easy to list, but would need a book to explain properly. A CPU contains .
a read only memory (ROM) containing some instructions for initial switch-on .
an address bus, which specifies a memory location to be read from or written to .
a main data bus, which carries data to or from memory. .
an instruction register, containing the instruction now being executed .
an address register containing the memory address wanted next .
an instruction counter, keeping track of where the next instruction will be found .
an arithmetic and logic unit (ALU) which does arithmetic and logical functions .
an instruction decoder, which, working in conjunction with the microprogram unit containing another ROM, sorts out what is done when and by which unit. .
various units moving data to and from the outside world via an input/output bus .
a clock and a clock-phase generator which ensures that different units work in sync. ( Full Answer )

How to reformat CPU?
You can not 'reformat' a CPU. The Central Processor Unit (CPU) of a computer is the heart of a PC that processes (like a huge bank of switches) the instructions and information passing through the computer. As such its configuration changes from microsecond to microsecond as you use the PC. The o…nly things you can reformat in respect to a computer are its data storage devices (normally disks) and the process usually involves overwriting anything that was on the disk before and starting clean. Be warned, if you reformat your system disk you will lose your computers operating system and it wont work afterwards! ( Full Answer )

Why does a CPU have a fan?
The fan protects the CPU from being destroyed. The CPU (Central Processing Unit) fetches and executes billions ofinstructions per second. The electric power it uses doing sogenerates heat. The heat can build up to the point where some partof the CPU can burn up or melt destroying the machine. Someco…mputers have circuitry to shut the computer when it gets too hotpreventing it from being damaged. A heat sink (a chunk of metal with radiating vanes) attached to theCPU draws the heat away from the CPU and a fan on top or side ofthe CPU or heat sink blows the heat away preventing the CPU fromgetting too hot. Without its own fan or CPU Cooler, the CPU would either fry or shutdown once the CPU temperature reached a specific temperature limitspecified in BIOS or CPU itself. The CPU cooler ensures the CPUoperates at a stable temperature. There is a new technology calledPWM (Pulse-width modulation) that will speed up the CPU Cooler'sfan as the processor becomes hotter under load in an effort to keepthe CPU at a low and stable temperature.

When was the 8 bit CPU invented?
Hard to say. .
The Colossus (1944) built to break German High Command teletypecyphers processed 8 bits of the code stream at a time. But only 5of the 8 were encrypted character data. .
Many 1950s business computers operated on characters instead ofwords, but these were usually 6 bit characters no…t 8 bitcharacters. .
The IBM 7030 Stretch (1961) defined a byte a a variable lengthof 1 to 8 bits. .
The IBM System 360 (1964) defined a byte as 8 bits. The360 was also the first computer to address memory at thebyte/character level, regardless of the size or type of data beingaccessed. The 360/20 and 360/30 implementations usedmicrocoded 8 bit processors to interpret the System 360 instructionset, but other versions of the 360 used processors with larger wordsize (both microcoded and hardwired logic implementations). .
During the minicomputer era CPUs were frequently either 12 bit(e.g. DEC PDP-8) or 16 bit (e.g. DEC PDP-11, Data General Nova) butthere may have been some 8 bit CPUs in this period. .
Intel's 8008 (1972) was the first 8 bit microprocessorCPU. Probably the microcoded 8 bit CPU of the IBM System 360/30,introduced in 1964 was the first 8 bit CPU ever delivered tocustomers. ( Full Answer )
