what is ram & rom memory in computer?

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.\n\nRAM (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.

I am going to assume that you mean on board memory.  You don't specify the operating system, so I will also assume that you are using Windows XP. If you click on System Information [accessories, system tools, then system information] you will see a lot of interesting data about your computer.  One of them is the total physical memory, and the available physical memory.  You will have more physical memory available when you have fewer processes begin at computer start up.\n\nFor example, with my computer the data shows I have 1GB total physical memory, and 735.30 MB of this memory free.

well there are many kinds of memory first is primary & second is secondary. if you r talking about primary well it is non - volatile memory & secondary is volatile. so it depends on the storage capacity also.if you r using primary memory the size will vary with 32,64,128,256,512 & 1 gb of memory  (RAM) and if u want to store more memory and want to store permanently then you need help of secondary memeory and that is hard disk.if varies from 2gb to 500gb or more now the latest hard disk comes upto morethan 100 terabites of space that is more than 10000 gb of space.

"Physical memory" is the actual amount of memory that your computer has. It's the Random Access Memory (RAM) cards that are plugged into your motherboard. When you read that a computer has "512 megabytes of DDR SDRAM," that's physical memory.\n\nGenerally, "Virtual Memory" refers to how an operating system can "fool" an appliation into thinking that the memory it is using is in one place, when actually it is in some other place. For example, the appliation might think it is using RAM, when in fact the operating system is storing the information on your hard disk drive or in some other place in RAM.\n\n"Logical memory" usually means the same thing as "virtual memory."\n\nFor more information about these terms, look them up at http://www.wikipedia.org

SRAM is short for Static RAM. This is a super high-speed Cache RAM that used to be on motherboards. It was usually in amounts of 32K, 64K, 128K, 256K and 512K, not megabytes. It's job was to contain frequently executed processor instructions for faster program execution. SRAM is not used on motherboards anymore due to the the large on-chip cache sizes of todays modern CPU's. CPU's have their own internal cache memory for fast instruction execution. They range in size from 128K all the way to 2MB.

Not enuff ram or too much crap running in the background eating your ram up!\n\nhere is how your computer works, you have two memory areas, ram and rom, rom is the place where your programs are stored whether it be a hard drve, a cd, etc.  now for the good part, ram is the area where your programs in rom are loaded to when you run them. lets say you have 256 megs of ram....you got a program running that uses 100 megs of ram, you got another program that uses another 100 megs also running, and last but not least you have another program running that uses 57 megs. guess what happens? you only have 256 megs of ram and you are using 257 megs of ram. things aint equatin rite! it may even run like this but, shit has to be dumped from ram and reloaded into ram to share the ram. this takes much time! sometimes it will lock you up even! the less crap you have running in the background the faster your computer will respond. got it? now....i can tell you weather alert eats lots of ram, morpheus eats lots of ram....you dont download from morpheus all the time do you? aint no point in it runnin! run it when you need it. adobe reader doesnt need to run...it will start automatically when you try to read an adobe file...

It's virtual memory. Memory which doesn't exist on the memory chips but is temporarily stored in a swap-file or paging file on the hard drive.

< RAM\n(Random Access Memory) A group of memory chips, typically of the dynamic RAM (DRAM) type, which function as the computer's primary workspace. When personal computers first came on the market in the late 1970s, 64KB (64 kilobytes) of RAM was the upper limit. Today, 64MB (64 megabytes) of SDRAM is entry level for a desktop computer, a thousand times as much (see SDRAM).\n\nThe "random" in RAM means that the contents of each byte of storage in the chip can be directly accessed without regard to the bytes before or after it. This is also true of other types of memory chips, including ROMs and PROMs. However, unlike ROMs and PROMs, RAM chips require power to maintain their content, which is why you must save your data onto disk before you turn the computer off. To learn about the types of RAM chips and how to upgrade your memory, see memory module. To learn how memory is used to process data, see computer or memory. See also dynamic RAM and static RAM.

well first of all RAM is random access memory so it can access data randomly not sequentially like in hdd that's y it works fast.\n  second property of RAM is that it is voletile that mean all the data will b removed from it as soon as u will put off the power supply so u can use a 4erased for fast data access but ur data will be stored till power supply is on , as soon as u will put off the power data will be earased

No you cannot. RAM sticks inside the PC are 'lightning fast' compared to USB sticks. USB are horribly slow.\nAlso, RAM memory is made so that it forgets everything when the power is taken away. USB sticks are the opposite. They are 2 completely different types of memory.

Assuming you have a windows Operating System..\n\n1. Right click on My Computer.\n2. Goto Properties. The General tab would display the amount of RAM.

RAM stands for Random Access memory\nROM stands for Read Only memory\n\nSo, when you burn a CD, that information may be accessed and used whenever you like, but it cannot be changed.\n\nWhen you start your computer, you access different files for writing, internet, etc and you alter and manipulate them. You send letters to friends, you type IM messages to family members.  That is using the RAM within your computer.

Usually if you take the RAM out of the computer, there is a sticker on it that will list the specs of the RAM.\n\nIf you are not comfortable opening the case, you have a program called "MSINFO" on most computers.  Go to C:&#92;Windows&#92;msapps&#92;msinfo" and run the MSINFO program.  This will give you many stats about your computer, including the RAM speed and type.
