Where the instruction execution happens?
Different parts of instruction execution happen in different places:Control Unit - fetches, decodes, and distributes decoded instructions to other units.Arithmetic Logic Unit - performs arithmetic and logic instructions on command from Control Unit.Input/Output Unit(s) - performs input/output instructions on command from Control Unit.Memory Unit - stores instructions and data, transfers them to/from other units on command from Control Unit.
What is the computers 'thinking work' done in?
The basic computer has two parts: Random Access Memory (RAM) and a Central Processing Unit (CPU) RAM is a place where many bytes are stored. One of the things that can be stored in RAM is a series of "instructions" that tell the CPU what to do. The series of instructions is called a "program." The CPU "fetches" one instruction from RAM, "executes" that instruction, then fetches and executes the next one, and so on. That is all that computers do. Whether that qualifies as "thinking" is a very controversial question.
What are the four distinct actions that a machine instruction can specify?
• The processor fetches the instruction from memory • Program counter (PC) holds address of the instruction to be fetched next • PC is incremented after each fetch • Fetched instruction loaded into instruction register
Why does data need to be stored?
"For later use" would be the quickest answer. The data stored maybe the result of an operation, it maybe the address of where to store the result or instruction. In your computer there is a starting point. The computer loads an address where initial instructions are located. These instruction usually flushes the memory, takes inventory of its Basic Input Output System and must remember if it is to communicate anything. Usually in typical PCs, it checks itself out- where is the memory, how much memory, devices connected (printer, display, disks etc). Dependent of many things, particularly the clock, it fetches instructions on how to read the disk and get instructions & data. If data is erased or changed prior to a execution, the computer may not function well due to bad data such as erroneous instruction, crazy & random addresses ... most likely the program will create an error condition so the CPU twiddles its thumbs in a random manner billions of times.
How does iis webserver work?
How a web server and web application server work togetherThe following steps explain how a web server and web application server work together to process a page request:The user requests a page by typing a URL in a browser, and the web server receives the request.The web server looks at the file extension to determine whether a web application server must process the page. Then, one of the following actions occur: If the user requests a file that is a simple web page (often one with an HTM or HTML extension), the web server fulfills the request and sends the file to the browser.If the user requests a file that is a page that a web application server must process (one with a CFM, CFML, or CFC extension for ColdFusion requests), the web server passes the request to the web application server. The web application server processes the page and sends the results to the web server, which returns those results to the browser. The following figure shows this process:Because web application servers interpret programming instructions and generate output that a web browser can interpret, they let web developers build highly interactive and data-rich websites, which can do tasks such as the following:Query other database applications for data.Dynamically populate form elements.Dynamically generate Flash application data.Provide application security.Integrate with other systems using standard protocols such as HTTP, FTP, LDAP, POP, and SMTP.Create shopping carts and e-commerce websites.Respond with an e-mail message immediately after a user submits a form.Return the results of keyword searches.A computer that delivers Web pages and work with http protocol. Every Web server has an IP address and possibly a domain name. For example, if you enter the URL http://www.pcwebopedia.com/index.html in your browser, this sends a request to the server whose domain name is pcwebopedia.com. The server then fetches the page named index.html and sends it to your browser.

Difference between microprocessor and instruction code?
difference between micro operation and microinstruction
Where does it begin when the microprocessor starts executes instructions?
During the start of execution, the microprocessor executes all instructions from BIOS. This in turn fetches the boot sector.
In which microprocessor does the concept of pipeline first introduced?
In 8086 pipeline concept was introduced bcoz in 8086 we started using a buffer space which fetches the instruction at the same time when CPU processes
Internal parts of a CPU and its function?
Arithmetic Logic Unit - performs arithmetic on numbers, logic functions, and manipulates symbols and strings of symbols.Control Unit - fetches and decodes instructions, controls operation of other units to execute the decoded instructions.Memory Unit - stores instructions, numbers, logical data, symbols, etc.Input/Output Unit(s) - moves instructions, numbers, logical data, symbols, etc. to and from the computer and devices outside it.
What are the relationship between cmos and bios?
The CPU depends on the BIOS to fetch instructions for processing and then to present it to the user after it is processed, The BIOS also depends on the CPU to process the information it fetches and sends back.
How does computers microprocessor work?
The basic computer has two parts: Random Access Memory (RAM) and a Central Processing Unit (CPU.) A microprocessor is a CPU that is built on a single chip. RAM is a place where many bytes are stored. One of the things that can be stored in RAM is a series of "instructions" that tell the CPU what to do. The series of instructions is called a "program." The CPU "fetches" one instruction from RAM, "executes" that instruction, then fetches and executes the next one, and so on. Exactly what the instructions in the program tell the computer to do determines how the computer will act at any given time.
What is fetching in microprocessor?
1) Fetch is the first of two stages involved in computer processing. The processor operates by processing instructions in what is called the "fetch/execute cycle." The processor fetches (reads from memory) an instruction and then, depending on the instruction, executes it (takes some further action with it, such as shifting bits to the right or left). Then it fetches the next instruction, and so forth.
