magnetic tape
A random access storage device, like a hard drive or SSD, can access information faster because it allows for direct retrieval of data from any location without the need to read through other data sequentially. In contrast, a sequential storage device, such as magnetic tape, requires the system to process data in order, often resulting in delays as it moves to the desired location. This characteristic of random access significantly enhances speed and efficiency when retrieving specific pieces of information.
optical
a sequential access is when one have to go though all the data to retrieve the data wanted therefore it is time consuming
name one access secondary device?
A hard disk is a Sequential Access Memory device or SAM
Direct access storage device
No.Another AnswerYes it is a Random Access storage device. You can tell this, because the last byte written on it's surface can be accessed without reading all the data bytes on the disk written before it. The drive can go directly to the last byte and read it off the surface. A tape (optical or magnetic) storage medium is Sequential, but an optical disk (CD/DVD) is Random.
