Generally referred to simply as MEMORY. This is where your system stores all the applications your computer is using at any given time. This is because it is all more quickly retrieved from here than from the HARD DISK. Once your computer is turned off, the information dissappears.
RAM, or system memory, is the workhorse behind the performance of your computer. RAM temporarily stores information from your operating system, applications, and data in current use. This gives your processor easy access to the critical information that makes your programs run.
This is the memory used by your computer to perform tasks, like running programs, doing calculations etc and it’s analogous to short-term memory in humans. When you run a software program, your computer copies it to the RAM and does all the work there. This allows the computer to run the software faster. RAM needs power (electricity) to work, however, so when your computer’s power is turned off, the RAM is erased. The software program is still on your system because your computer copied the working parts of it to RAM but any new information that you created whether text, spreadsheets, graphics and is kept in RAM until you save it. That is why you need to continuously save your information to your hard drive or disk.
Computer memory that can be both read and written to, and can be accessed in a random fashion, as compared to a sequential fashion, such as tape access. This is the memory typically used to store the instructions necessary to run a software program.
The memory available to the user in which data can be read from or written to, directly, at a high rate of speed, by means of its address. Random access memory in microcomputers is usually volatile in that it loses it contents when the computer is turned off.
Chips which can be called read/write memory, since the data stored in them may be read or new data may be written into any memory address on these chips. The term random access means that each memory location [usually 8 bits or 1 byte] may be directly accessed [read from or written to] at random. This contrasts to devices like magnetic tape where each section of the tape must be searched sequentially by the read/write head from its current location until it finds the desired location. ROM memory is also random access memory, but they are read only not read/write memories. Another difference between RAM and ROM is that RAM is volatile, i.e. it must have a constant supply of power or the stored data will be lost.
(abbreviation: RAM) The working memory of the computer into which application programs can be loaded and executed. It helps to have more of this "working space" installed when running advanced operating systems and applications.
Backup memory of game information is stored in the CMOS RAM chip on the processor board. CMOS memory (complementary metal oxide semiconductor) is a battery powered memory, used to store backup RAM data.
Temporary storage area that the processor uses to execute Program s & hold Data. Information is put into RAM & held there. Once the RAM becomes full information has to be removed to make space for the current task being performed. A PC with limited RAM will take a long time to perform the simplest task as the information in the RAM is constantly being replaced. RAM requires a constant electric supply to keep the information intact. Should you switch off the PC then you will lose the contents of RAM forever. Different areas of RAM include: Conventional Memory; Expanded Memory; Extended Memory; High Memory Area; Upper Memory Area. Types of RAM include: DRAM; EDO RAM; SDRAM.
In general, the computer's primary working memory in which program instructions and data are stored and are accessible to the CPU. Information can be written to and read from RAM. The contents of RAM are lost when the computer is turned off.
is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor. RAM is much faster to read from and write to than the other kinds of storage in a computer such as the hard disk, floppy disk, and CD-ROM.
the most common computer memory which can be used by programs to perform necessary tasks while the computer is on; an integrated circuit memory chip allows information to be stored or accessed in any order and all storage locations are equally accessible
( RAM or also sometimes called "central memory"): fast-access volatile memory. Programs are usually loaded into RAM for quick execution, which is more convenient for the user (read/write times are about 1000 faster on RAM then on a hard disc).
Short-term, temporary memory that holds the operating system, programs and files currently in use. When you turn the computer off, RAM loses its data. The more RAM you have, the less frequently the computer has to access instructions and the more quickly it can operate. Return to .
Memory in a computer that can be read and written to instantly. It has no capacity to store data without power, so before a computer can be turned off, applications must be saved to a disk of some kind or another.
The memory that temporarily stores program data actively running on a computer. Data stored in RAM is available only as long as a computer stays on. As soon as the computer is turned off, the data disappears. This is why files must be saved in more permanent storage places (hard disks, floppy disks, etc.) In order to be retrieved after a computer is turned off. Computers load active programs into RAM rather than hard drives or floppy disks so they can access the data much faster. RAM is typically measured in Megabytes or MB, and most computers today come with 64 to 128 MB of RAM.
Memory stored internally that can be read and modified by the user. RAM is the temporary workspace that is used while the user is logged onto the system. It is basically where the computer lives while it is awake. You need RAM to allow you the ability to work on your system while it is turned on.
Volatile memory, which can be written as well as read. More specifically, it is semiconductor-based memory that can be read or written by the CPU or other hardware devices. The storage locations can be accessed in any order.
Temporary memory. Files and programs are stored in permanent memory, like a hard drive or a CD-ROM. When you run a program, it is moved into RAM. In general, more RAM means a faster system. There are exceptions; for example, although Windows 98 will recognize if you have more than 128 megabytes, it will not use more than that.
A semiconductor (silicon chip) memory medium, in which suitably encoded instructions and/or data may be recorded, recovered, altered and re-recorded repeatedly, in a random fashion (that is, in no particular order relative to the addresses of the memory locations involved). When a computer is running, RAM holds the program (including the system) and data currently running.
A series of integrated circuits containing registers, which hold instructions pertinent to applications and documents. RAM contents are loaded froma storage device. RAM contents are lost when a computer is shut off or power is interrupted. Short-Term Memory See Save, Storage.
(RAM)—One or more microprocessors that a computer can access to store data temporarily. Unlike magnetic hard disks or "floppy" diskettes, which can store data indefinitely, RAM is purged of its contents when the computer is restarted, shut down or otherwise loses power.
The short term memory of a computer. The random access memory (RAM) stores recent and frequently used information and commands, which enables programs to operate more efficiently. If programs require more RAM than you have available, then information and commands must be stored on the computer's hard drive -- the computer's long term memory. It is more difficult for a computer to access information from the hard drive, so it takes longer. Programs operate sluggishly or crash frequently when there is not enough RAM. The more RAM your computer has, the faster programs can function. The primary limitation on the performance gains you can realize by adding RAM to your computers is the speed of their processors.
Memory where any location can read from or write to in random order. RAM usually refers to volatile memory where the contents are lost when power is removed. The user-addressable memory of a computer is random access memory.
Circuitry in a computer that temporarily holds data the CPU can access to perform user-requested tasks. In general, more RAM allows a CPU to work faster, because data is moved into and out of RAM less frequently.
(RAM): The place in the computer where the operating system, applications programs, and data in current use are kept temporarily. When the computer is turned off, the data are removed from RAM and either stored elsewhere in the computer or deleted.
A computer's working memory. The RAM, which is expressed in kilobytes or K, is used by the computer to load and run a program as well as to manipulate and store information. The RAM is a temporary storage system in that once the computer is turned off, the information, with the exception of a special form of RAM used by some laptop computers is lost or disappears.
The working memory of the computer. RAM is the memory used for storing data temporarily while working on it, running application programs, etc."Random access" refers to the fact that any area of RAM can be accessed directly and immediately, in contrast to other media such as a magnetic tape where the tape must be wound to the point where the data is. RAM is called volatile memory; information in RAM will disappear if the power is switched off before it is saved to disk.
The programmable area of the computer's memory that can be read from and written to (changed). All RAM locations are equally accessible at any time in any order. The components of RAM are erased when the computer is turned off.
the computer's volatile memory. When the power is off, the memory is empty. This is also the memory that can be randomly accessed by the computer's central processing unit (CPU); so information to be used actively must reside in RAM. (The hard drive is used for non-volatile storage, and information is transferred to RAM for actual use. Specific information on the hard disk cannot be located for random access by the CPU.) When RAM is insufficient for a specific purpose, some of the information will be placed in a special portion of the hard drive for retrieval -- often called the swap disk, and there will be a swapping of information between RAM and the hard drive so that the actively-used information is in RAM. That is a marginally effective process on most PCs; so using large files effectively requires more RAM than business-oriented machines normally need. (Virtual memory serves the same purpose of substituting space on a hard disk for RAM, and, although not identical in function, it suffers from the same speed problems.)
Computer memory that is accessed randomly. Any byte of memory can be accessed without accessing the surrounding bytes. RAM is a common type of memory found in computers and other hardware devices, such as printers.
The memory that is used to run applications and perform other necessary tasks while the computer is on. When the computer is turned off, all information in RAM is lost. When PC's were first introduced, they could address as much as 640K RAM. With the advent of X86 architecture and DOS upgrades, this barrier was broken and increased to 32Meg (32,000K) of RAM. Microsoft's Windows NT has promised to break this barrier and be able to address up to 32Gigs (32,000,000K) of RAM.
A data storage device for which the order of access to different locations does not affect the speed of access. RAM is usually volatile, meaning that it does not retain its contents when the power is switched off.
Random access memory (usually known by its acronym, RAM) is a type of data store 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.
