what is the use of RAM in computers?how much RAM should we use in windows xp?

Answer 1

Random Access Memory - Google it.
512M and up.

Answer 2

RAM is a temporary storage device in a computer. When the computer is shut down, there will be no data in Ram. Ram stores the information about the data or programme we are currently using. So if we have lots of ram, we can open more programmes at the same time and the computer will still perform faster and efficiently. So more the amount of ram in a computer the better the performance and efficiency of the computer will be.

RAM (Random Access Memory) is a temporary (Volatile) storage area utilized by the CPU. Before a program can be ran the program is loaded into the memory which allows the CPU direct access to the program. RAM is usually used for primary storage in computers to hold active information such as data and programmes. It requires practically the same amount of time to access any piece of data stored in a RAM chip. The disadvantage of RAM is the loss of data when power is turned off.
ROM or Read Only Memory, Computers almost always contain a small amount of read-only memory that holds instructions for starting up the computer. Unlike RAM, ROM cannot be written to. It is non-volatile which means once you turn off the computer the information is still there. ROM stores critical programs such as the program that boots the computer.
Ram allows you to store softwares and data. And rom allows you to store data even the computer is turned off and helps you in booting. So we need both Ram and Rom in a computer.

Answer 3

RAM is a memory place used by computer to temporary store the data during processing. For windows XP, 512 MB is enough & 1 GB is excellent for gaming applications.

Answer 4

RAM stores processes that the processor can use very quickly. Virtual Memory in hard disk can do the same but at a very SLOW pace.

Win XP runs great on 2x512mb (dual channel) mode, especially when nothing is shared w/ onboard video because there is a discrete video card. Additional RAM will give diminishing return.

Answer 5

RAM is the temporary memory for the data u work with. it is volatile and goes off when u shut down the system

WIN XP requires atleast 64 MB but better with atleast 512 MB when u work with graphics or 256 MB when u work with text

the more the RAM the faster is the system

Answer 6

hi,
ram - random access memory is like a scrap book that we use for temporary jotting. actually windows uses physical ram and another one called the virtual ram or paging file. whenever we use windows, that programs gets loaded into the memory (RAM) and once that program has quit windows flushes the memory.
windows xp requires a bare minimum of 256mb memory. use atleast 512mb or more for good performance.

Answer 7

My computer (Windows XP SP2) uses around 250 MB of RAM at idle, right after startup. Nothing is resident in memory except the ATI Catalyst Control Panel & Drivers and the Windows Desktop Search 3.01 Indexer. Games like Battlefield 2 & FEAR alone take about 1GB of RAM (running with all settings maxed) so having 1.5GB+ is recommended. Applications like Sony Vegas (Non-Linear Editor), Maya (3D Suite) and Adobe Photoshop (Imaging) will eat any RAM you have faster than you can say WHOA. If you are editing RAW images, uncompressed multi-channel audio or High-Definition Video (HDV or AVCHD), be prepared for hell.

Under normal usage - Firewall, Anti-Virus real-time scanner, two chat clients, a few Firefox windows, Windows Media Player, uTorrent etc. - I see RAM usage go up to 400MB. Run a MeGUI/VirtualDub encoding project in the background and it goes higher. Throw in a Photoshop batch job and your hard drive will start thrashing. 1GB is bare minimum for WinXP if you use your computer for any semi-serious productivity. Windows Vista easily hits 600MB at startup. Choose according to your needs.

As for the function, RAM stores data in a high-speed quick-access storage space for quick access by the CPU. Data is static information on your hard drive while a process is a program currently in execution and assigned CPU time. RAM is where a process is executed. Depending on your CPU architecture, motherboard and memory modules, RAM allows sequential read/write operations as high as 8GB/s in modern systems. A single hard drive likely sustains ~40-70MB/s depending on the model so you can see RAM is much faster. Latency goes down to 50ns compared to ~10ms for a hard drive.

Answer 8

Random access memory (RAM) is the best known form of computer memory. RAM is considered "random access" because you can access any memory cell directly if you know the row and column that intersect at that cell.

The opposite of RAM is serial access memory (SAM). SAM stores data as a series of memory cells that can only be accessed sequentially (like a cassette tape). If the data is not in the current location, each memory cell is checked until the needed data is found. SAM works very well for memory buffers, where the data is normally stored in the order in which it will be used (a good example is the texture buffer memory on a video card). RAM data, on the other hand, can be accessed in any order.

Answer 9

RAM is Random Access Memory
It helps increase the speed of u'r pc
For XP a minimum of 128mb would do well
I would recommend a minimum of 256mb

All the Best....

Answer 10

RAM (Random Access Memory), the more of it you have, the faster it will go.
XP will actually run on just 64mb RAM, but just try it!! The recommended minimum is 128mb though, but try that aswell.
I wouldn't run XP on anything less than 512mb personally, but it will obviously run on less.

Answer 11

for windows XP 512 mb of RAM is sufficient.
