Pandas also supports the syntax data.iloc[n], which always takes an integer n and returns the nth value, counting from 0. This allows a user to act as though the index is an array-like sequence of integers, regardless of how it's actually defined. [9]: 110–113 Pandas supports hierarchical indices with multiple values per data point.
() operations, which force us to visit every node in ascending order (such as printing the entire list), provide the opportunity to perform a behind-the-scenes derandomization of the level structure of the skip-list in an optimal way, bringing the skip list to () search time. (Choose the level of the i'th finite node to be 1 plus the number ...
9-track tape drive used with DEC minicomputers Inside a 9-track tape drive. The vacuum columns are the two gray rectangles on the left. A typical 9-track unit consists of a tape transport—essentially all the mechanics that moves tape from reel to reel past the read/write and erase heads—and supporting control and data read/write electronics.

The ability to copy a large file or a large selection of files (up to 1.5TB uncompressed data for LTO-5, and 18TB for LTO-9) to an LTFS formatted tape, allows easy exchange of data to a collaborator, or the saving of an archival copy.
Bluefield Retread Company in Bluefield, West Virginia. Retread (also known as recap or remold) is a re-manufacturing process for tires that replace the tread on worn tires. [1] [2] Retreading is applied to casings of spent tires that have been inspected and repaired. [3]
When the first data band is filled (they are filled in 3, 1, 0, 2 order across the tape), the head assembly is moved to the second data band and a new set of wraps is written in the same linear serpentine manner. The total number of tracks on the tape is (4 data bands) × (11 to 52 wraps per band) × (8, 16, or 32 tracks per wrap).
Reel-to-reel preceded the development of the compact cassette with tape 0.15 inches (3.8 mm) wide moving at 1 + 7 ⁄ 8 inches per second (4.8 cm/s). By writing the same audio signal across more tape, reel-to-reel systems give much greater fidelity at the cost of much larger tapes.
