3 results for scan'
From Webster's Revised Unabridged Dictionary (1913) [web1913]:
   Scan \Scan\ (sk[acr]n), v. t. [imp. & p. p. {Scanned}
      (sk[acr]nd); p. pr. & vb. n. {Scanning}.] [L. scandere,
      scansum, to climb, to scan, akin to Skr. skand to spring,
      leap: cf. F. scander. Cf. {Ascend}, {Descend}, {Scale} a
      ladder.]
      1. To mount by steps; to go through with step by step. [Obs.]
  
                     Nor stayed till she the highest stage had scand.
                                                                              --Spenser.

From The Free On-line Dictionary of Computing (15Feb98) [foldoc]:
   scan
  
      1. (computer peripheral) See {scanner}.
  
      2. (circuit design) See {scan design}.
  
      3. ({functional programming}) See {scanl}, {scanr}.
  
      4. An algorithm for scheduling multiple
      accesses to a disk.   A number of requests are ordered
      according to the data's position on the storage device.   This
      reduces the disk arm movement to one "scan" or sweep across
      the whole disk in the worst case.   The serivce time can be
      estimated from the disk's track-to-track {seek} time, maximum
      seek time (one scan), and maximum {rotational latency}.
  
      {Scan-EDF} is a variation on this.
