Random Access

In computer systems, the ability to access any point of a sequence in an equal amount of time. Random access contrasts with sequential access, in which different points in a sequence take varying amounts of time to access. Random access is also called direct access.

Disk libraries and tape libraries: aiming for peaceful coexistence

The ASACA TeraCart libraries are the world's highest-density, random-access storage solution and can be configured with 1 to 192 DVD-RAM drives and up to 11,600 double-sided 9.4GB rewritable DVD discs for capacities ranging from 2.3TB to more than 109TB.

Because some are random-access storage mediums, using the same technology as your hard disk, applications stored on them can be run directly on your computer--with no need to first download them onto your hard disk, as would be necessary with tape storage.

Running out of storage space

A cell's internal and external environment affect the concentration and activities of those many macromolecules, giving rise to what Bray calls a "memory trace." As with a computer's random-access memory, which serves as temporary storage for transient information, a cell's proteins maintain a record of its ever-changing surroundings.

Do proteins in cells make computations?

The systems' random-access and automated features allow tests to be run at any time and in any order as needed, eliminating the need for expensive pensive batch testing of multiple patient samples.
