The solid of revolution obtained by revolving a rectangle about a side is called a cylinder, or more precisely a right circular cylinder. More generally the word cylinder is used in solid geometry to describe any solid bounded by two parallel planes and a portion of a closed cylindrical surface. In analytic geometry, however, the word cylinder refers not to a solid but to a cylindrical surface (see illustration). This is a surface generated by a straight line which moves so that it always intersects a given plane curve called the directrix, and remains parallel to a fixed line that intersects the plane of the directrix. Cylinders whose right sections are circles, ellipses, parabolas, or hyperbolas are called circular cylinders, elliptic cylinders, parabolic cylinders, or hyperbolic cylinders, respectively. All these are quadric cylinders. See also Euclidean geometry.

Cylindrical surface.

The aggregate of all tracks that reside in the same location on every disk surface. On multiple-platter disks, the cylinder is the sum total of every track with the same track number on every surface. On a floppy disk, a cylinder comprises the top and corresponding bottom track.

When storing data, the operating system fills an entire cylinder before moving to the next one. The access arm remains stationary until all the tracks in the cylinder have been read or written.

Cylindrical devices on a printing press, including plate cylinders, blanket cylinders, and impression cylinders. In direct printing, the impression cylinder presses the paper against the plate cylinder. In offset printing, the blanket cylinder is pressed against the paper, transferring the image from one surface to another.

In a lock, the cylindrically shaped assembly containing the tumbler mechanism and the keyway, which can be actuated only by the correct keys.

A term used to describe a transaction, involving two derivatives, where there is no initial cost bourne by the investor when entering into the position.

Investopedia Says:
For example, an investor can sell a derivative and use its proceeds to purchase another security. A cylinder is different from a positive carry trade since it does not necessarily imply offsetting positions.
