  2. External memory algorithm - Wikipedia

    en.wikipedia.org/wiki/External_memory_algorithm

    The external memory model is an abstract machine similar to the RAM machine model, but with a cache in addition to main memory. The model captures the fact that read and write operations are much faster in a cache than in main memory , and that reading long contiguous blocks is faster than reading randomly using a disk read-and-write head .

  3. Memory module - Wikipedia

    en.wikipedia.org/wiki/Memory_module

    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 ...

  4. Computer memory - Wikipedia

    en.wikipedia.org/wiki/Computer_memory

    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.

    en.wikipedia.org/wiki/List_of_Hebrew_abbreviations

    In fact, a work written in Hebrew may have Aramaic acronyms interspersed throughout (ex. Tanya), much as an Aramaic work may borrow from Hebrew (ex. Talmud, Midrash, Zohar). Although much less common than Aramaic abbreviations, some Hebrew material contains Yiddish abbreviations too (for example, Chassidic responsa, commentaries, and other ...

  6. Non-volatile random-access memory - Wikipedia

    en.wikipedia.org/wiki/Non-volatile_random-access...

    To date, the only such system to enter widespread production is ferroelectric RAM, or F-RAM (sometimes referred to as FeRAM). F-RAM is a random-access memory similar in construction to DRAM but (instead of a dielectric layer like in DRAM) contains a thin ferroelectric film of lead zirconate titanate [Pb(Zr,Ti)O 3], commonly referred to as PZT ...

  8. Memory virtualization - Wikipedia

    en.wikipedia.org/wiki/Memory_virtualization

    Virtual memory systems abstract between physical RAM and virtual addresses, assigning virtual memory addresses both to physical RAM and to disk-based storage, expanding addressable memory, but at the cost of speed. NUMA and SMP architectures optimize memory allocation within multi-processor systems. While these technologies dynamically manage ...
