2. Optical storage media writing and reading speed - Wikipedia

   en.wikipedia.org/wiki/Optical_storage_media...

   Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering. As faster drives were released, the write speeds and read speeds for optical discs were multiplied by manufacturers, far exceeding the drive speeds originally released onto the market.

3. Random-access memory - Wikipedia

   en.wikipedia.org/wiki/Random-access_memory

   Prior to the development of integrated read-only memory (ROM) circuits, permanent (or read-only) random-access memory was often constructed using diode matrices driven by address decoders, or specially wound core rope memory planes. [citation needed] Semiconductor memory appeared in the 1960s with bipolar memory, which used bipolar transistors ...

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.

5. DVD-RAM - Wikipedia

   en.wikipedia.org/wiki/DVD-RAM

   DVD-RAM media have been used in computers as well as camcorders and personal video recorders since 1998. [1] In May 2019, Panasonic, the only remaining manufacturer of DVD-RAM discs, announced that it would end production of DVD-RAM media by the end of that month, citing shrinking demand as the primary motivation. [2]

6. List of films with high frame rates - Wikipedia

   en.wikipedia.org/wiki/List_of_films_with_high...

   This is a list of films with high frame rates.Only films with a native (without motion interpolation) shooting and projection frame rate of 48 or higher, for all or some of its scenes, are included, as are films that received an official post-conversion using technologies such as TrueCut Motion.

7. 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. ‘Caught in 4k’: What the slang phrase really means - AOL

   www.aol.com/news/caught-4k-slang-phrase-really...

   The online dictionary explains that “4k” number “Refers to 4,000 pixel resolution, a very high resolution for video and digital photography that results in clear images.”

9. Semiconductor memory - Wikipedia

   en.wikipedia.org/wiki/Semiconductor_memory

   RAM (Random-access memory) – This has become a generic term for any semiconductor memory that can be written to, as well as read from, in contrast to ROM (below), which can only be read. All semiconductor memory, not just RAM, has the property of random access. DRAM (Dynamic random-access memory) – This uses memory cells consisting of one ...
