What application instruction that make the computer hardware work?

Answer 1

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.

Answer 2

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).

Answer 3

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

Answer 4

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
