You are working in computer and your computer can not keep cought everything in it,is it possoble? The answer is yes and the condition is that if your competer has no ram,then it possible. Then what is ram? The ramisthe part of a computer’s memory available to execute programs and temporarily store data. The memory to which the operator has random access can usually be used for both reading and writing. Unless the file has been saved, RAM data are automatically erased when the computer is turned off.Other sense: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
Types:
There are two different types of RAM: DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory). The two types differ in the technology they use to hold data, with DRAM being the more common type. In terms of speed, SRAM is faster. DRAM needs to be refreshed thousands of times per second while SRAM does not need to be refreshed, which is what makes it faster than DRAM. DRAM supports access times of about 60 nanoseconds, SRAM can give access times as low as 10 nanoseconds. Despite SRAM being faster, it's not as commonly used as DRAM because it's so much more expensive. Both types of RAM are volatile, meaning that they lose their contents when the power is turned off.
This contrasts with storage mechanisms such as tapes, magnetic discs and optical discs, 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.
History
An early type of widespread writable random access memory was the magnetic core memory, developed from 1949 to 1952, and subsequently used in most computers up until the development of the static and dynamic integrated RAM circuits in the late 1960s and early 1970s. Before this, computers used relays, delay line memory or various kinds of vacuum tube arrangements to implement "main" memory functions (i.e., hundreds or thousands of bits), some of which were random access, some not. Latches built out of vacuum tube triodes, and later, out of discrete transistors, were used for smaller and faster memories such as registers and (random access) register banks. Prior to the development of integrated ROM circuits, permanent (or read-only) random access memory was often constructed using semiconductor diode matrices driven by address decoders
Software can "partition" a portion of a computer's RAM, allowing it to act as a much faster hard drive that is called a RAM disk. Unless the memory used is non-volatile, a RAM disk loses the stored data when the computer is shut down. However, volatile memory can retain its data when the computer is shut down if it has a separate power source, usually a battery.
Desktops have had the PC2-6400 DDR2 800MHz generation for a quarter or more, but the Fully Buffered and ECC Registered and now in this higher performace speed market as well. The 2nd gereration Apple Mac Pro and xServe have shown to be some of the first to use this newest entry into the FBDIMM market.
Need a single 4GB desktop DDR2 module. If your running a 64-bit version of Windows Vista basic, premium Ultimate, Business or Enterprise you can now load that slot up with 4gb chips! With motherboards for desktop PC computers having only four sockets at time you can now get the MAXIMUM available memory you need.
Latest speed of FBDIMM and RDIMM modules to market:
