Who invented the CPU?
J. Presper Eckert and John William Mauchly, invented the EDVAC, perhaps the first computing machine with the "stored-program" architecture typical of modern CPUs.
That architecture is called the "von Neumann architecture" after John von Neumann, who write a widely distributed paper about the EDVAC.
Some people incorrectly believe that
Intel, as a company invented the first CPU.
While it is true that the people at Intel built the first microprocessor (a CPU on a single chip), the 4004, in 1971, which was a great achievement at the time,
there were a variety of other, previous CPUs built out of a few dozen integrated circuits, a few thousand individual transistors, or a few thousand vacuum tubes.
The first commercially available computer was the 1951 Ferranti Mark 1, designed by Freddie Williams and Tom Kilburn at the University of Manchester.
IBM sold about 20,000 of the refrigerator-sized IBM 1401 CPUs first introduced in 1959.

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 register 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
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 arithmeti…cal, 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.
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 Eck…ert and John Mauchly were the first to patent a digital computing device, the ENIAC. The ABC had been examined by John Mauchly in June 1941, and Isaac Auerbach,  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".
In 1971 on the month of November.
John Vincent invented the keyboard in October 1896.
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 o…f 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.
A CPU is basically a brain CPU stands for C entral P rocessing U nit Every thing is processed at this thing or chip
it is central processing unit of the computer.
1964 - 1971
It stands for Central Processing Unit, as is where all the calculations are carried out.
it stands for the central processing unit and it is basically the brain of the computer, every bit of data has to go through it, this is what determines your multitasking info…, max graphic capabilities and so on.
Unknown. Stored program electronic digital computers were discussed during WW2 on project PX (ENIAC) but nobody recorded who came up with the idea.. 100 years earlier Babbage… invented his Analytical Engine. Its Mill could be considered the first CPU, but it was all mechanical (and was never built)..

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 charac…ter data. . Many 1950s business computers operated on characters instead ofwords, but these were usually 6 bit characters not 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.
