computer architecture refers to how a computer and specificly how a processer move and processes data.\nyou can chech the major processor manufacuters sites( amd and intel) for information on how thier cpu's do this and how they interact with the motherboards.\n\nthis is a deep and complex subjet

I'll try to keep this simple...\n\nThe processor is the primary "computing" part of the computer.\n\nThe vast majority of computers have a "single core" processor.  The thing runs so fast for most applications that when doing multiple applications, such as opening up several windows/programs, it appears as if everything is happening at the same time.  But, in reality, it is doing what is called, "multitasking."  The processor gives some time to this application, sort of puts a bookmark where it left off, goest to the next application, sort of puts a book mark where it left off, etc., until each process has had a share of time, then it goes back to the book mark of the first process, and the cycle continues.\n\nDual core processors are capable of true parallel processing, which means doing 2 applications at the same time.  To effectively use this, the operating system and software have to be able to perform this.  Windows XP can do it, but again, the application software needs the ability.\n\nQuad core processors means 4 parallel processes running simultaneously.  The same considerations are given to the operating system and software capabilities.\n\nBoth dual and quad processors have all the processors on the same chip, which means things execute quicker than if there are 2 or more separate processors on the same motherboard.  It takes longer to process with separate processors because the information has to run on the system bus, with speed limitations due to several factors.  \n\nI hope this helps.

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.

depends on a number of things.......basically need more info about your computer

I think you'll need to be a bit more specific in what type of help your actually looking for.  Are you more interested in education on how to use and operate a machine?  Want to know the intricate technical workings of how your machine performs?  Having an OS issue?  Machine lagging and you want to improve performance?  Thinking about upgrading that video card for the next best thing?  There are plenty of websites that cover all of that in varying degrees depending on where your interests lie.

That depends on if you need info about YOUR processor or processors in general. If it's about your processor, your best bet is to type into google your PC's model number ans the word "specs", and maybe "processor" as well, and you should be able to find a page with your specific computer's processor type. \nIf you need more information or are looking for info on other processors, sites that sell them, like www.newegg.com or www.microcenter.com should have fairly detailed specifications.\nIf you're just looking for a brief tutorial on CPU's, I can tell you a little bit here: the CPU is the central processing unit of your computer. It is whatdoes the calculations for the computer. CPU's are rated according to clock speed, and will have a number in gigahertz (GHz) showing the speed. However, speed is not the only determining factor. Some processors can do more calculations per second, but some also need more as they are not efficient, or are slowed down by the way they transfer information to the rest of the computer. A processor must fit the motherboard it is on, which means they must be of matching socket types (you'll find this info with the rest of the CPU's specs). Some CPU's are "dual core" which means there are essentially 2 processors working together to speed things up, although this will not be as fast as double the clock speed. (ie, a dual-core 1.5 GHz will not be the same as a single core 3 GHz) Processors can also be either 32-bit or 64-bit, and 64-bit is becoming more popular, as it will be able to support new, advanced software in the future. If you're buying a processor, also consider the type of memory that goes with the motherboard, as some kinds are faster than others. There are more advanced things, as well, but that's about the extent of my knowledge. If you have more questions, just post them and I'll see what I can do.

That depends on what you mean by "computer".  The basis of any computing machine is the ability to do input, processing and output.  The core of what makes it a computer is to handle "whatif" questions and to respond differently based on the answer to those questions.  For example, to say, "If the dollar amount is less than X then do this, but if it's greater than X then do that.\n\nBy that definition, the first true computer would probably be Charles Babbage's "Difference Engine" built in the late 1800s.  An improved version, which he called the "Analytical Engine" actually accepted punch card programs, the first of which was written by Lord Byron's daughter, Ada Lovelace, making her the world's first computer programmer.\n\nThe first truly modern electronic computer was, arguably, the ENIAC developed for the US Army by the University of Pennsylvania.  I say "arguably" because it depends on which features you want to include in the definition of "modern electronic computer."  For example, the ENIAC had no stored memory and had to be rewired for each program.\n\nHope this helps.

The systematic study of computing systems and computation. The body of knowledge resulting from this discipline contains theories for understanding computing systems and methods; design methodology, algorithms, and tools; methods for the testing of concepts; methods of analysis and verification; and knowledge representation and implementation.

Wikipedia.com will get you started. A massive online encyclopedia is what it is. Just do a search on "electronics" to strart with. You will find an article, and as you get into it, you will see links to other key words (such as certain components) which you can then click and read. Like a massive network of knowledge. Once you really get into it, Wikipedia also provides external links at the bottom of articles to get a more in-depth look at it.

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.

Here's the simple version:\nComputers have\nA brain (CPU or central processing unit)\nMemory \nStorage\nPeripherals\nThe CPU is like an air traffic controller controlling all your requests and running all your programs.\nThe Memory holds the programs - including your OS (windows etc.) and data temporarily for the CPU to access.\nStorage such as a hard disk drive holds information when it is too large or inconvenient to place in memory and when the computer is shut down.\nPeripherals: Keyboard, mouse, monitor, printer are what the computer uses to interact with the Human.\n\nThe CPU manages all your interactions : running programs, copying files, surfing the web.  It uses the resources it needs (peripherals, memory, storage etc.) to fulfill those requests. \nImagine you have a private chef, who is locked in his own kitchen.  You make a request to him.  He produces the food and uses his resources, pots, pans  ingredients, recipes etc.  He's like your CPU.\n\nIt goes much further than that, but I hope that helps.
