Ram stands for Random Access Memory. It allows data to both be written and accessed on the chip in any order placed on it. ROM stands for Read Only Memory. As the name suggests, you can only get data from it (read). You normally can't write to it. A PC's bios is a good example.

Read-only memory (ROM), also known as firmware, is an integrated circuit programmed with specific data when it is manufactured. ROM chips are used not only in computers, but in most other electronic items as well. RAM ( Random access memory is used by your computer and the data held on it changes frequently the more Ram you have, the easier it will be on your CPU when you are running a few programmes at the same time.

I would just like to add to scubabob's fabulous answer that ROM holds its data even after the power is turned off. RAM does not - turn the power off and the data is gone.

RAM = random access memory ROM = read only memory

read only memory is non volatile, while random access memory is volatile, which means it loses everything without power on.

Ram gets erased if there is no power to it, rom does not need a constant power source.

Ram and Rom are same = memory one is read-only memory and buffer store

RAM is random access memory, it is lost when the computer is switched off. ROM is read only memory and it is permanent. The most obvious example is the BIOS (Basic Input Output System) which is a tiny permanent program that runs when you turn on your computer and it prepares disk drives and processor to load the operating system from disk.

RAM = Random Access Memory it is volatile meaning when the power is cut then it gets a "memory wipe" in other words loses all information. - ROM = Read Only Memory is nonvolatile and has stuff "flashed or burned" on it so its permanent even with power off.

RAM stands for Random Access Memory.It will allow information to both be written and reached on the chip in a random order. ROM stands for Read Only Memory.As it's name suggests, you can only get data from it by reading.Sometimes you can't write to it.A computer bios is a very excellent example.

RAM is Random Access Memory. It is a volatile type of memory that needs electricity to flow to retain information. It is the type of memory that computers use to process programs. ROM is Read Only Memory. Essentially it is a piece of permanently written information stored as memory. There are versions of this memory that can be rewritten but it is then called EPROM (Erasable Programmable Read Only Memory) and generally takes ultraviolet light to clear. The easiest way to understand the difference is to think of this as a blackboard. When memory is being used as RAM, it's a blackboard that is constantly being rewritten and then washed and rewritten, thousands of times per minute. If it was ROM, the writing would be in acrylic paint, that can't be removed. EPROM would be the same paint but it can be removed by very special and specific means.

RAM: (Previously "direct-access memory"). A data storage device for which the order of access to different locations does not affect the speed of access. This is in contrast to, say, a magnetic disk, magnetic tape or a mercury delay line where it is very much quicker to access data sequentially because accessing a non-sequential location requires physical movement of the storage medium rather than just electronic switching. In the 1970s magnetic core memory was used and some old-timers still call RAM "core". The most common form of RAM in use today is semiconductor integrated circuits, which can be either static random-access memory (SRAM) or dynamic random-access memory (DRAM). The term "RAM" has gained the additional meaning of read-write. Most kinds of semiconductor read-only memory (ROM) are actually "random access" in the above sense but are never referred to as RAM. Furthermore, memory referred to as RAM can usually be read and written equally quickly (approximately), in contrast to the various kinds of programmable read-only memory. Finally, RAM is usually volatile though non-volatile random-access memory is also used. Interestingly, some DRAM devices are not truly random access because various kinds of "page mode" or "column mode" mean that sequential access is faster than random access. The humorous expansion "Rarely Adequate Memory" refers to the fact that programs and data always seem to expand to fill the memory available. Hardware inside your computer that retains memory on a short-term basis and stores information while you work. RAM is one of the things that make your computer run faster. It comes in 32-bit, 64-bit, 128-bit, 256-bit, and higher, and you can add additional "blocks" of RAM, depending on your computer. Slang usage of this term often describes someone who does not possess the mental capacities required for the task at hand, as in, "I wouldn't ask him to do it, he's a little short on RAM." Actual RAM comes in a variety of forms: DRAM (Dynamic Random-Access Memory): A memory chip contained on such devices as video and sound cards. ROM: A type of data storage device which is manufactured with fixed contents. In its most general sense, the term might be used for any storage system whose contents cannot be altered, such as a gramophone record or a printed book; however, the term is most often applied to semiconductor integrated circuit memories, of which there are several types, and CD-ROM. ROM is inherently non-volatile storage - it retains its contents even when the power is switched off, in contrast to RAM. ROM is often used to hold programs for embedded systems since these usually have a fixed purpose. ROM is also used for storage of the lowest level bootstrap software (firmware) in a computer. Built-in computer memory that can be read but not written to. ROM contains the programming that allows your computer to boot up each time you turn it on, and it contains essential system programs that neither you or the computer can erase. Unlike a computer's random access memory (RAM), ROM does not lose its data when the computer power is turned off. It is sustained by a small, long-life battery. (If you ever run the hardware setup procedure on your computer, you are in effect writing to ROM.) ROM can also refer to Rough Order of Magnitude, referring to the amount of time it takes to accomplish a given task. The BIOS of a mother board is made of ROM.

wahat is ram an rom ?

RAM memory can and does change, it can be written over. ROM is 'set'. That is it is written once and then unchanged under normal use.

A & O

Random access memory and read only memory

RAM is Randomly Accessible Memory. It is used for the operation of programs. It can be written to and read from but when the power shuts off it looses it's data. ROM is Read Only Memory. It's permanent, usually holds a piece of software needed for computer functionality. It will hold it's data when the computer is off.

RAM is Random Access Memory. It is a temporary state memory that your comouter uses to run programs. All the information in your RAM is deleted when your computer is turned off. ROM is read-only memory. If you ever wondered why CD ROMs are called CD ROMs, it is because you cannot edit the data on the CD.

(i)RAM MEANS RANDOM ACCESS MEMORY. (ii)WHEN POWER ON CPU,RAM MEMORY PRESENT OR TEMPORARY STORAGE AND BOTH READ & WRITE OPERATIONS DONE (iii)128 words for eight bits & eight bits data bus

ROM = Read Only Memory RAM = Random Access Memory ROM you write to once and read many times. RAM you both read and write to.

RAM (Random access memory) is storage that your computer can both create and read. ROM (Read-only memory) is storage (usually on discs and CDs) that your computer can ONLY read. It cannot change the information it reads. The amount of RAM your computer has really determines how many programs of functions you can be running at once. I read a good example somewhere online... RAM is like a field, programs and functions will take up space in that field. Once space runs out, you cannot run anymore than that. But, once a program is taken out, its spot is open again for another program to use. But not to worry, many computer have enough RAM to compensate for their programs. You can check RAM space (total, free, and used) in system information, located under the start menu (programs>accessories>system information). Now, to ROM. ROM, such as a CD, can only be read by your computer. Your computer cannot change the data that its reading off the CD. Thats basically ROM..."read-only" memory.

DIFFERENCE BETWEEN COMPILER AND ENTERPRETER.

My answer is: R.A.M means Random Access Memory, this allows you to temporary store data, all data will be lost unless it is saved to youor hard disk(drive). R.O.M means Read Only Memory, this allows you acces data that has been permanently stored on a storage device such as a finalized disk.
