In terms of storage units, magnetic tape is a form of serial access, where a disk provides direct access. If you think of a cassette tape, you would have to fast forward or rewind to get to a... Direct-attached storage (DAS) is digital storage directly attached to the computer accessing it, as opposed to storage accessed over a computer network. Examples of DAS include hard drives , solid-state drives , optical disc drives , and storage on external drives .

A direct (or random) access storage device is one that stores files so that they can be instantly accessed - there is no need to search through other files to get to the one you want. An example of a direct access device would be a DVD movie. Unlike the VHS videotape movie, you can jump to any scene on a DVD. All parts of the DVD are directly accessible. This type of file storage is called medical device marketing strategy pdf The 3380 Model CJ2 provides both the storage functions of a 3380 direct access storage and the storage control functions of a 3990 model I (the two storage path model) in a single unit.
