What is the RAM in computer and what is the use of it?

Answer 1

I think of it as your desk working area. The bigger the desk, the more easily you can grab papers and look at it.

Otherwise, if your desk is too small (less RAM), you have to file the paperwork, in a file cabinet (harddisk) and when you want to see that paper again, you have to get up and fetch it from the cabinet. It takes longer.

The computer processor loves to have a a lot of RAM, remember where the 'papers' are by an address number, and not have to 'fetch' things from the storage cabinet (harddisk).

Now-adays for a new computer, 512 "megs" is OK for Windows XP, or maybe 1 "gig" worth of memory (twice 512). I run Win XP on a Pentium II, with 128 megs. I strip out all the services, no virus checking, etc. and the 'footprint' for the operating system for memory usage is just 77 megs, - leaving about 50 megs left for Internet Explorer, or MS Word. That seems to work fine.

Answer 2

Now, there is a question I'd never expect to see here... I thought everyone who ever owned a computer knows.

Anyway, RAM stands for Random Access Memory. It is the place where temporary data are stored. For instance, if you start writing a Word document, your text will be stored in the RAM while you are writing it. When you press "Save" or "Save as...", only then will your document be stored in the hard disk drive (or diskette or USB flash drive or... whatever!)

Everything that is stored inside RAM will be erased when you turn off or restart your computer, unless you save that data on your hard disk.

I assume you wonder "why aren't the data saved in the hard disk drive directly?" First of all, RAM is much faster than the hard disk drive. It would be impossible for the hard disk to write and erase data at the rate RAM does, especially in more demanding applications than Word processing. Additionally, you may actually not want to save a particular file that you create or decide that some changes that you made to it were not that good and prefer the old version of a file.

Answer 3

The processor handles data very fast ... and the Hard Disk which has the data is very slow because its stores the data physically on a magnetic surface.

So for the processor to work as fast as it can without waiting for the hard disk to bring the data to it, they created something called RAM ( random access memory).
It's job is to save a large amount of data and keep it ready for the processor for fast access to frequently used data.

The data will be stored on the RAM as long as it has electricity. That's why its called Volatile Memory.

Simply, it's a very crucial part of the computer and is one of the top fife elements in measuring the performance of the computer.

The more RAM you have, the faster the processing is. Because the ram would be able to store everything the processor needs and therefore save it from accessing the slow hard disk.

Answer 4

Random access memory (usually known by its acronym, RAM) is a type of data store used in computers that allows the stored data to be accessed in any order — that is, at random, not just in sequence. In contrast, other types of memory devices (such as magnetic tapes, disks, and drums) can access data on the storage medium only in a predetermined order due to constraints in their mechanical design.

Answer 5

RAM - Random Access Memory, it is dat part of memory dat comes into life when an application is invoked, all the stuff dat is needed for the aplication is stored in RAM from secondary storage like HDD or CD ..............

Answer 6

RAM is random access memory
whenever u r running a program on ur pc,the file is extracted from the harddisk into the ram.
the more ram u have,the more programs u can run at a time.
right now it is 2GB.
