What is RAM?

Answer 1

RAM is Random Access Memory. RAM is the area where your computer stores programs that you are currently running and data that you are currently working on.

RAM can be contrasted with disk storage. Disk storage holds all of your programs and all of your data -- whether you are working with them or not. When you turn off your computer, the contents of RAM instantly disappear, but the contents of your disk storage remain unharmed.

RAM is also sometimes contrasted with ROM. ROM (Read Only Memory) are memory chips which have had information stored on them which cannot be changed. Your motherboard may contain some ROM chips.

Answer 2

Ram= Random Access Memory. It helps Computer to digest informations.

Answer 3

RAM is random access memory; the 256 or 512, or 1 gig or so of memory you have on you computer that you can use to access info, bring up your saved info and when you turn off you computer it is gone -- unless you saved it to your hard drive or cd or some other storage device; you access that stuff my transfering to your RAM, ie, when you double click it it is put in RAM so you can see what you have stored.

Answer 4

Random Access Memory

Answer 5

Let me explain simply.

As you know repeated 30x Random Access Memory.

but what RAM does is something special. Your Hard Drive is used to save information like word files and saved games, things that when you turn off your computer you want them to be there when you get back. But what RAM does is it stores what you are using currently, like word, or firefox, or iTunes.

Its basically the memory that holds what your doing, as you do it. Then when you shut down your computer it goes away. Thats why you must always saveee.

Random Access Memory (usually known by its acronym, RAM) is a type of data storage used in computers. It takes the form of integrated circuits that allow the stored data to be accessed in any order — that is, at random and without the physical movement of the storage medium or a physical reading head.

The word "random" refers to the fact that any piece of data can be returned quickly, and in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data. This contrasts with storage mechanisms such as tapes, magnetic disks and optical disks, which rely on the physical movement of the recording medium or a reading head. In these devices, the movement takes longer than the data transfer, and the retrieval time varies depending on the physical location of the next item.

Answer 7

Yes. Random Access Memory. It's where your computer does all its calculations while you're watching it. When it's done what you want it to, you"save" the result (the file) onto the hard disk, which holds it after you turn the machine off. RAM only works when you are using the computer - that's what it's for, to save you adding up all those ones and zeros.

Answer 8

There are two basic types of RAM:

dynamic RAM (DRAM)
static RAM (SRAM)

The two types differ in the technology they use to hold data, dynamic RAM being the more common type. Dynamic RAM needs to be refreshed thousands of times per second. Static RAM does not need to be refreshed, which makes it faster; but it is also more expensive than dynamic RAM. Both types of RAM are volatile, meaning that they lose their contents when the power is turned off.

In common usage, the term RAM is synonymous with main memory, the memory available to programs. For example, a computer with 8M RAM has approximately 8 million bytes of memory that programs can use. In contrast, ROM (read-only memory) refers to special memory used to store programs that boot the computer and perform diagnostics. Most personal computers have a small amount of ROM (a few thousand bytes). In fact, both types of memory (ROM and RAM) allow random access. To be precise, therefore, RAM should be referred to as read/write RAM and ROM as read-only RAM.

the CPU (central processing unit). When people refer to a computer's memory, they usually mean its RAM.

New computers typically come with at least 256 megabytes (MB) of RAM installed, and can be upgraded to 512MB or even a gigabyte or more.

If you add more RAM to your computer, you reduce the number of times your CPU must read data from your hard disk. This usually allows your computer to work considerably faster, as RAM is many times faster than a hard disk.

RAM is volatile, so data stored in RAM stays there only as long as your computer is running. As soon as you turn the computer off, the data stored in RAM disappears.

When you turn your computer on again, your computer's boot firmware (called BIOS on a PC) uses instructions stored semi-permanently in ROM chips to read your operating system and related files from the disk and load them back into RAM.

Note: On a PC, different parts of RAM may be more or less easily accessible to programs. For example, cache RAM is made up of very high-speed RAM chips which sit between the CPU and main RAM, storing (i.e., caching) memory accesses by the CPU. Cache RAM helps to alleviate the gap between the speed of a CPU's megahertz rating and the ability of RAM to respond and deliver data. It reduces how often the CPU must wait for data from main memory.
