Examples of data sets include price indices (such as consumer price index), unemployment rates, literacy rates, and census data. In this context, data represent the raw facts and figures from which useful information can ...
Computer data storage. 1 GiB of SDRAM mounted in a computer. An example of primary storage. 15 GB PATA hard disk drive (HDD) from 1999. When connected to a computer it serves as secondary storage. 160 GB SDLT tape cartridge, an example of off-line storage. When used within a robotic tape library, it is classified as tertiary storage instead.
