How does the data store in ur pc hard disk when u enter a data how the cpu memory play its role in this proce

Answer 1

Its a typicall and thechnical ques. i hope you'll understand it. I'll tell it wid most basic way to tell

All the data you input goes to CPU (central processing unit) It processes on data Via the processor (The fastest part included speed in GHz).where procesor list the data whether it is character or number etc. then it enlist the operations to be perfomed on data i.e. ADD , MULTIPLY etc. all these temporary data stores on RAM and quickly deleted. RAM is second most speedy thing here(The speed of RAM is in accordance to motherboard support which in turn in accordance to processor.And at last when whole process is done (in few nanoseconds) the data is stored on Hard disk.

Now we hae two conclusions.

a.> Overall speed depends on

         1.>Processor - 1.1>Cache memory (L1, L2 , L3)

                              1.2> Processor speed in GHz

         2.> RAM - 2.1>RAM's Memory (512 MB or 1 GB or 2 GB)

                         2.2> RAM speed (533 FSB 633 FSB or else)

         3.> Hard disk optimum ideal speed (It is specified like 1.5 GB/s or 3 GB/s)

b.> Never put two RAM's of different speed in Slots as it can conflict. Eg. you are performing a calculation. Both are giev half-half part . one wud give you result faster while other will give you slowly and hence there would be a conflict

I'd not included or explained things like registers , cache memory ALU etc. as it will elongate the answere and will be complicated to understand

Answer 2

it depends on the program tat reads or writes data to system.

for eg. some program may store all the data on memory temporarily, then will finally write it to hd. The other may write it instantaneously.

But all these requests will be satisfied by the OS.

The OS, according to the file system of the hd, will manage files.

thats all i know....  

Answer 3

the hard drive stores data in 0 n 1's dat is the only thing ur comp understands n the hardware stores data in current form dat is - volts n +volts the 0's n 1's r converted into currents. dats all i know

Answer 4

Imagine that you are saving a 1-Mb Word document on the hard disk. Saving a 1 MB file means the disk will systematically 'fill in' a thousand squares.

After saving the Word document, let us assume that you saved to your hard disk a 3 MB photo. Following the key concepts of data storage, the disk writer head will go through the disk and then look for the first available space – which in our example, happens to be the square following the last kilobyte of the Word document. Thus, the 3 MB photo will be saved at the space next to the Word document.

Afterwards, you go back to your Word document and trim it down, ending up with a file 700 KB in size, which you then save to your hard disk. Given the smaller file size, the 1 MB space requirement was reduced to 700 KB, leaving 300 KB free or (using the analogy above) 300 blank squares immediately after the Word document. There's now available space between the Word Document and the 3 MB photo.

When you save yet another file, say a 2 MB Excel file, the hard disk will follow its rule of saving data on the first available space. Thus, the Excel file will be split into two portions: 300 KB would be written on the 300 KB free space and the rest will be placed in the next available space – after the image file.

Its speed depend on the RPM (revolution per minute) of the Hard disk.
