In computer the datas are taken from ROM and then procesed in main memoryWhy it should not be processed in ROM

Answer 1

Because ROM stands for "read only memory" - the computer can't write any new data (including intermediate results) into the ROM. Main memory is RAM, or random access memory, which can be read to and written to an unlimited number of times. ROM is only programmed once when the computer is manufactured or a similar piece of electronic hardware is built.

Dear man..
I am not agree with the answer posted here.
Both Memory can work to serve processing.
Like you have seen in many other application.ROm is used every where.where the need of memory is there.
In Simple words ROM (Read Only Memory) means a Piece of memory where user intrection is not at all needed says in the case of Simple Cir in Popular Audio Application.
Means User Simply Plays nothing else.
In the case of older Bios when you just need to Boot the system Nothing else (Offcourse you need to read 200 Pages Manuale to set a seconday Hard Disk etc.)
In case of Normal Hard Disk Operation ROM is used (Means why you need to know how the data is processed into Parallel to serial comunication ie. To Operate the Hard Disk ROM is Configured and Get fitted with SMT (Surface Mounting Technique).No User At all.

Apart from this RAM is the main memory is store you intermediate results.Thats why we need RAM to do our ragular task.
But I Really appose that ROM Could not process the Data.
It Could Process (In reality Actually the Data is Process Through the ROM Not RAM atleast)
For those guys who could not believe this

We are using Processor to do processing (A processor is Bigger ROM (For NON_TECHNICAL STUFF READING THIS)
And For Technical stuff it is VLSI.(Very Large Scale Intregated Ckt).Kindly Read Books to clearlyfy this.

ROM Also acts as Memory But Compared with RAM it is slower.
Thats why We Use Both Technology.ROM for storing up instruction not to be changed by user.(Example Hard Disk/FDC/Older Bios/..ect)
Recent Bios Don't use ROM instead EEPROM is used (Recall of setting up a jumper will destroy the data stored)


And RAM (Basically Flipflops) Stores the Data for normal operation.

I hope this is a bit help full to you

As the name implies, you cannot write to read-only memory; your system can only read it during normal operation. The computer manufacturer preprograms the data; the data will remain intact without any power. Random-access memory allows the CPU to read and write information at any time. This information is erased, however, when you turn the system's power off. We can further differentiate RAM chips between Static RAM (SRAM) and Dynamic (RAM) (DRAM), depending upon whether the data in the cells needs to be refreshed. (SRAM doesn't need to be refreshed.)

Generally u know computers use ROM for :-
When you power on a computer, it needs to load the system-initialization program(boot-strap loader) from OS. Early PCs required the operator to manually set the device address. However, this data is now stored in the complementary metal-oxide semiconductor (CMOS) or is at a fixed location. In the PC, the location is an address with-in a ROM chip called the Basic Input/Output system (BIOS, a special piece of software that controls the startup process of a computer and other basic functions).

And RAM is basically used for :-
The processor in a computer runs more than a million times faster than the typical auxiliary storage devices can operate (nanoseconds vs. milliseconds). For this reason, it is necessary to have a fast, temporary repository for the data that the system is most likely to request, which RAM is particularly suited for.

Answer 4

Dear Friend, You Know what is the work of Rom(read only memory), When our Computer start Rom instruct the system that where our data is saved and from where system have to boot and then Rom job is Finished, now RAM Job is start, RAM(main memory) collect all the information and data from hard disk, which is necessay to open operating system and then Then job Of Processer is start it recive all data and information from RAM perform some operation on that and give the result(output) on output device then you see that your 98 or Xp operating is opend and you are ready to perform any other job(process). and when you turn of your Computer all the inmotmation from RAM are lost but in ROP data never lost. So when you start again your system Ram again give same instruction. there are different types of ROM so please study about that..

Answer 5

Because that is only memory so only
