The CPU does all the actual work and there can easily be a hundred or more separate instructions that a modern CPU understands, each of which does a very minute job, whether it is to move a value into a register or into memory, or to compare register values, or to perform simple arithmetic upon them, and so on. Common interfaces provided by the BIOS allow the CPU to interact with the basic hardware components in order to load an operating system, while the operating system itself provides more specific device control via driver software.
A computer is an electronic machine that takes some input, does some calculation on that input and produces an output. Inputs are programs (sets of instructions to do things) and data (the objects that get manipualted by the programs). Physical inputs (like key presses, mouse clicks and so on) get translated to program instructions and data. Outputs are simply data that is shoved somewhere by a program (eg: onto a screen, printer or into a sound device). In order for the machine to keep track of where it is in its programs, it requires memory. when switched off it loses the memory so it has to start again. computers have hard disks to store important programs and data that it would take too long for the user to type in each time it was switched on (like Windows for example).
Step 1
Data is entered through input devices e.g. keyboard.
Step 2
Control Unit (CU) After receiving instruction from the main memory to sent signal and commands , CU sent signal and commands to various part of the computer system to prepare and accept the data. After the data is processed it is sent back to main memory which stores it temporarily before the next command is executed. The data is then send to secondary storage devices after secondary storage device had received command from the Control Unit. For the information to be put into a hard copy i.e. paper, the information moves from the secondary storage device to the main memory which waits for signals and commands from Control Unit. After receiving signal from the Control Unit that the output devices are ready to receive data, the main memory releases the data to the output devices like printers, plotters for printingprinters, plotters for printing
cpu is known as mind of computer .as we give instructions to it it works on it as it transffer our data in bqinary mode and than work on it for giving results to the users
"An Input device is any piece of computer hardware equipment used to provide data and control signals to an information processing system (such as a computer). Input and output devices make up the hardware interface between a computer and the user or external world " - Wikipedia Egs. Keyboard , mouse etc. Whereas, MSWord is part of the Microsoft office which is an application s/w introduced by Microsoft in 1989. So, obviously it's not a DEVICE!
AnswerAn application is a program in general, for instance, Internet Explorer, Microsoft Word and Notepad.A process is single instance of an application whilst it is running.
The IT structure beneath a structure includes software programs. These are also known as computer programs which are non-tangible components of computer that represent sets of programs that govern the operation of a computer system and make the hardware run.
Computer applications make it easier for employees to carry out the functions of their jobs. With software, the business can input data quicker instead of creating templates each time.
p { margin-bottom: 0.1in; line-height: 120%; } I think there are two branches of computer engineering technology: Hardware and Software Hardware : Focusing on making a computer itself and make sure it can run (Basically work on everything you see or can touch) They need to know some programming.Software: Focusing on Programming the machines. (work on everything you can't fiscally see or touch) Coding, designing the database or operating systems.So you call those people: Hardware engineer and Software engineer Thank youDariush from Wickenburg.net
System software helps to increase the functions of hardware for supporting various application.
Computer programs are categorized into system and application software. To make a complete computer system, programs (software) works hand in hand with hardware.

Computer hardware is the components that make up a computer. Computer architecture is the model used to combine the Hardware into a working unit.
In computer hardware, "cards" usually refers to the different silicon boards that make up the hardware of a computer.
Hardware - the physical components, both internal and external, that make up a computer. Operating System - a set of computer programs that manages the hardware of a computer. An operating system controls the resources on a computer, including memory and disk storage. An example of an operating system is Windows XP. Application Software - programs loaded on the computer to perform a specific function using the capabilities of the computer. An example of application software is a word processor or a computer game
Hardware
Internet Explorer is a software application on your computer. Hardware is something that you can physically touch (in most cases). Software is what runs on the computer to make the hardware work.
Circuitry. All a computer is, is Circuitry.
