A portion of the computer's hard drive is set aside for a paging file or a scratch partition, and the combination of physical RAM and the paging file form the system's total memory. (For example, if a computer has 2 GB (1024 3 B) of RAM and a 1 GB page file, the operating system has 3 GB total memory available to it.)
The operating system will place actively used data in RAM, which is much faster than hard disks. When the amount of RAM is not sufficient to run all the current programs, it can result in a situation where the computer spends more time moving data from RAM to disk and back than it does accomplishing tasks; this is known as thrashing.
i-RAM Version 1.3 PCI-Card with 4 x 1 GB DIMM. The i-RAM [1] was a PCI card-mounted, battery-backed RAM disk that behaved and was marketed as a solid-state storage device. It was produced by Gigabyte and released in June 2005, [2] at a time when genuine solid-state storage solutions were generally still less affordable than an i-RAM product with superficially similar capabilities.
Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory ; data is lost when power is removed.
Associated with speed, the more RAM there is in the system, the faster the computer can run, because it allows the RAM to run more information through to the computer's (CPU). Not only does adding more RAM to a computer help it run faster, it helps boots up a computer immensely faster compared to booting up a system with less RAM.
RAM drives use normal system memory as if it were a partition on a physical hard drive rather than accessing the data bus normally used for secondary storage. Though RAM drives can often be supported directly in the operating system via special mechanisms in the OS kernel, it is generally simpler to access a RAM drive through a virtual device ...
Synchronous graphics RAM (SGRAM) is a specialized form of SDRAM for graphics adaptors. It is designed for graphics-related tasks such as texture memory and framebuffers , found on video cards . It adds functions such as bit masking (writing to a specified bit plane without affecting the others) and block write (filling a block of memory with a ...
In computing, a memory module or RAM stick is a printed circuit board on which memory integrated circuits are mounted. [1] Memory modules permit easy installation and replacement in electronic systems, especially computers such as personal computers, workstations, and servers. The first memory modules were proprietary designs that were specific ...
