what is central processing unit explain?

CPU\n\nAlso known as a processor or microprocessor the CPU was first developed by Intel in 1974 and is short for Central Processing Unit. The computer CPU is responsible for handling all instructions and calculation it receives from other hardware components in the computer and software programs running on the computer. Below is a graphic example of what the Intel Pentium processor looked like.

An operating system is a computer program that manages the hardware and software resources of a computer.\n\nThe kernel is the central component of most computer operating systems.\nThe difference is that Kernel is central to the OS, but there are also other components which help the kernel. ( Like observing the user input )

It is a single chip that has dual processor cores.  I have it on my laptop and it's great! Software today can't really take advantage of it, but future software will.  Currently the biggest benefit comes while multitasking.

from the American Heritage Dictionary: it is "The main board of a computer, usually containing the circuitry for the central processing unit, keyboard, and monitor and often having slots for accepting additional circuitry."

Canit explain in small space, try http://www.cpu-world.com/Arch/6800.html and http://pages.cpsc.ucalgary.ca/~dsb/PDP11/\n\nHave used pdp 11 in the past to study data.\nIt is a bit unwieldy, if you are unfamiliar with it.

You'll have to be more specific.  \n\nDo you mean CPU, Central Processing Unit?\nOr a processor in a cell phone?

In computing, the kernel is the central component of most computer operating systems (OSs). Its responsibilities include managing the system's resources and the communication between hardware and software components. As a basic component of an operating system, a kernel provides the lowest level of abstraction layer for the resources (especially memory, processors and I/O devices) that applications must control to perform their function. It typically makes these facilities available to application processes through inter-process communication mechanisms and system calls.\n\nclick here:http://en.wikipedia.org/wiki/Kernel_%28computer_science%29

The kernel is the main part of the operating system that connects the hardware to the software portion of the computer. The kernel runs the drivers of each hardware device that will make each compont run well with each other. This is just a basic explanation of what the kernel does, there is an advance cousre in Computer Science degree devoted entirely to the theory of the kernel and the archetecture.

Basically the Central Processing Unit (CPU) does the work. CPU (and any other computer component) only understands 1 and 0. Making a string of these (like 111000101011) tells the CPU what to do based on its programmed instructions.  Then the CPU processes the correct data (information that only computers understand...like 1 and 0) into information (what we understand..as in what is being displayed on the monitor). \n\nThe CPU has two main core divisions:\n\nThe ALU (arithmetic logical unit) which calculates basic math AND\nThe Control Unit, which handles advanced math and everything else.

This is the central processing unit (CPU) in your computer.  It is the brains of the machine and executes the programs that you run.  The MHz refers to the speed that it operates, in millions of cycles per second.  Intel Pentium is one brand, an equivalent is made by AMD (K6 and so on).  \n\nCD Rom Drive is the unit that you stick the CD into to read the program into the computer.  \n\nSounds like you are reading system requirements off a software box, in which case they are trying to tell you what your computers capabilities need to be in order to run the program.  They usually require a certain speed processor, CD Rom Drive, some hard disk space, and a given amount of system memory.  \n\nStart -> Programs -> Accessories -> System tools -> System Information should tell you the specs that your computer has.  \n\nGenerally speaking, much older computers don't run the newest software well, try to find a program that came out about the same time as the computer, or within a couple of years.  \n\nGood luck, and don't be afraid to put more details in your questions in the future.

A computer chip is effectively a collection of electrical logic circuits tied to a clock signal. What this means is that there is a set of binary inputs, and every time a clock signal 'ticks', the chip reads those inputs and computes an output (also in binary form).\n\nEach computer chip has a set of operations it can perform. This is known as the "instruction set". These instructions can range from the very simple (add two numbers; multiply two numbers; check if a first number is bigger than a second number) to the complex, but they all basically come down to reading the input and computing some output.\n\nThe clock is used to control the pace of computation. This is what people mean when they talk about processor speed, clock speed, and MHz / GHz. It's basically the pace at which your CPU is crunching through these individual computation cycles.\n\nSo everything your computer does basically boils down to the set of simple instructions your chip supports (add, subtract, multiply, etc.) Anything from running Windows, computing your income taxes, piloting the space shuttle, playing mp3 files, and so on are really just very complex arrangements of lots and lots of these simple operations actually performed by the chip.
