Memory bandwidth is the rate at which data can be read from or stored into a semiconductor memory by a processor. Memory bandwidth is usually expressed in units of bytes/second , though this can vary for systems with natural data sizes that are not a multiple of the commonly used 8-bit bytes.
For CDs, the 1× writing speed is equivalent to the 1× reading speed, which in turn represents the speed at which a piece of media can be read in its entirety, 74 minutes. Those 74 minutes come from the maximum playtime that the Red Book (audio CD standard) specifies for a digital audio CD (CD-DA); although now, most recordable CDs can hold 80 ...
MemTest86 and Memtest86+ are memory test software programs designed to test and stress test an x86 architecture computer's random-access memory (RAM) for errors, by writing test patterns to most memory addresses, reading back the data, and comparing for errors. [6]
The refresh cycles are distributed across the entire refresh interval in such a way that all rows are refreshed within the required interval. To refresh one row of the memory array using RAS only refresh (ROR), the following steps must occur: The row address of the row to be refreshed must be applied at the address input pins.
Competitive typist Albert Tangora demonstrating his typing in 1938. Touch typing (also called blind typing, or touch keyboarding) is a style of typing.Although the phrase refers to typing without using the sense of sight to find the keys—specifically, a touch typist will know their location on the keyboard through muscle memory—the term is often used to refer to a specific form of touch ...
Ronald Carver, a professor of education research and psychology, claims that the fastest college graduate readers can read only about 600 words per minute, at most twice as fast as their slowest counterparts, and suggests that Kennedy's claimed reading speed was more a measure of how fast he could skim a piece of text.

DVD-RAM (DVD Random Access Memory) is a DVD-based disc specification presented in 1996 by the DVD Forum, which specifies rewritable DVD-RAM media and the appropriate DVD writers. DVD-RAM media have been used in computers as well as camcorders and personal video recorders since 1998.
