    en.wikipedia.org/wiki/List_of_HTTP_status_codes

    This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection. [2]A user agent may carry out the additional action with no user interaction only if the method used in the second request is GET or HEAD.

  4. ECC memory - Wikipedia

    en.wikipedia.org/wiki/ECC_memory

    DRAM memory may provide increased protection against soft errors by relying on error-correcting codes. Such error-correcting memory, known as ECC or EDAC-protected memory, is particularly desirable for highly fault-tolerant applications, such as servers, as well as deep-space applications due to increased radiation.

  5. Memory Reference Code - Wikipedia

    en.wikipedia.org/wiki/Memory_Reference_Code

    The MRC is part of reference BIOS code, which relates to memory initialization in the BIOS. It includes information about memory settings, frequency, timing, driving and detailed operations of the memory controller. The MRC is written in a C-language code, which can be edited and compiled by board makers. It provides a space to develop advanced ...

    The feeling that a person gets when they know the information, but can not remember a specific detail, like an individual's name or the name of a place is described as the "tip-of-the-tongue" experience.

    en.wikipedia.org/wiki/Dynamic_random-access_memory

    In 1985, when 64K DRAM memory chips were the most common memory chips used in computers, and when more than 60 percent of those chips were produced by Japanese companies, semiconductor makers in the United States accused Japanese companies of export dumping for the purpose of driving makers in the United States out of the commodity memory chip ...

  8. DDR5 SDRAM - Wikipedia

    en.wikipedia.org/wiki/DDR5_SDRAM

    Unlike DDR4, all DDR5 chips have on-die error-correction code, that detects and corrects errors before sending data to the CPU, to improve reliability and allow denser RAM chips which lowers per-chip defect rate. However, on-die error-correction code is not the same as true ECC memory with extra data correction chips on the memory module. There ...

    en.wikipedia.org/wiki/Bank_switching

    While the contents of memory temporarily switched out from the CPU was inaccessible to the processor, it could be used by other hardware, such as video display, DMA, I/O devices, etc. CP/M-80 3.0 released in 1983 and the Z80-based TRS-80s the Model 4 and Model II supported bank switching to allow use of more than the 64 KB of memory that the ...
