University of Manchester. If needed, contents of the computer memory can be transferred to secondary storage, through a memory management technique called "virtual memory". Improper management of memory is a common cause of bugs, including the following types:. Each word can be accessed by a binary address of N bit, making it possible to store 2 raised by N words in the memory. Presper Eckert in the early 1940s. Main article: Volatile memory. Two alternatives to the delay line, the Williams tube and Selectron tube, originated in 1946, both using electron beams in glass tubes as means of storage. Examples of volatile memory are primary storage, which is typically dynamic random-access memory (DRAM), and fast CPU cache memory, which is typically static random-access memory (SRAM) that is fast but energy-consuming, offering lower memory areal density than DRAM.

[.] Windows Server Enterprise supports clustering with up to eight-node clusters and very large memory (VLM) configurations of up to 32 GB on 32-bit systems and 2 TB on 64-bit systems. This article includes a list of references, but its sources remain unclear because it has insufficient inline citations. Main article: Non-volatile memory. Windows Server 2008 Inside Out. The Williams tube would prove more capacious than the Selectron tube (the Selectron was limited to 256 bits, while the Williams tube could store thousands) and less expensive. p.1520. When a program needs memory, it requests it from the operating system. At times programs intentionally alter the memory used by other programs.
