<p><b>New page</b></p><div>The term '''skew''', generally referring to some difference from an expected or optimal value, is common in both [[telecommunication]]s and [[mathematics]].<br />
<br />
== Telecommunication ==<br />
<br />
* In [[parallel transmission]], the difference in arrival time of bits transmitted at the same time. <br />
<br />
* For [[data]] recorded on [[multichannel]] [[magnetic tape]], the difference between [[reading (technical)|reading]] times of bits recorded in a single transverse line. <br />
<br />
''Note:'' Skew is usually interpreted to mean the difference in reading times between bits recorded on the tracks at the extremities, or edges, of the tape. <br />
<br />
* In [[facsimile]] systems, the angular deviation of the received frame from rectangularity caused by asynchronism between the [[scanner]] and the recorder. <br />
<br />
<i>Note:</i> Skew is expressed numerically as the tangent of the deviation angle. <br />
<br />
* In facsimile, the angle between the [[scanning line]], or recording line, and the perpendicular to the paper [[path]].<br />

<br />
== Mathematics ==<br />
<br />
* In [[statistics]], skew can refer to the [[skewness]] of a distribution.<br />
* In [[linear algebra]], a [[skew-symmetric matrix]] is a matrix which is the negative of its own transpose.<br />
* In [[geometry]], [[skew line]]s are lines which do not intersect yet are not parallel.<br />
