Buffer may refer to:

Buffer (rail transport)

A buffer is a part of the buffers-and-chain coupling system used on the railway systems of many countries, among them most of those in Europe, for attaching railway vehicles to one another.

Fitted at the ends of the vehicle frames, one at each corner, the buffers are projecting, shock-absorbing pads which, when vehicles are coupled, are brought into contact with those on the next vehicle. The draw chain used between each pair of vehicles includes a screw which is tightened after coupling to shorten the chain and keep the buffers pressed together. Such is known as a 'screw coupling'. Historically, coupling chains were no more than that, a short length of heavy chain (typically three links long) with no adjustment. These would result in a 'loose-coupled train' in which the buffers of adjacent vehicles would only touch when the coupling chain was fully slack, such as when being pushed or going down hill.

Although the buffers in the very earliest days of railways were rigid (dumb buffers), they soon came to be spring-loaded, while those fitted to modern locomotives and rolling stock incorporate oleo-pneumatic shock absorbers.

Buffer (optical fiber)

In a fiber optic cable, a buffer is one type of component used to encapsulate one or more optical fibers for the purpose of providing such functions as mechanical isolation, protection from physical damage and fiber identification.

The buffer may take the form of a miniature conduit, contained within the cable and called a "loose buffer", or "loose buffer tube". A loose buffer may contain more than one fiber, and sometimes contains a lubricating gel. A "tight buffer" consists of a polymer coating in intimate contact with the primary coating applied to the fiber during manufacture.

Buffer application methods include spraying, dipping, extrusion and electrostatic methods. Materials used to create buffers can include fluoropolymers such as polyvinylidene fluoride (Kynar), polytetrafluoroethylene (Teflon), or polyurethane.

Buffer (disambiguation)
Buffer (GIS)

A buffer in GIS is a zone around a map feature measured in units of distance or time. A buffer is useful for proximity analysis.

A buffer is an area defined by the bounding region determined by a set of points at a specified maximum distance from all nodes along segments of an object.

Buffer (navy)

Buffer is the colloquial title for the senior seaman sailor in a Commonwealth of Nations navy ship. The formal title is chief boatswain's mate.

This person is typically a chief petty officer or petty officer in frigates or destroyers, and in larger ships may be a warrant officer. In smaller ships, such as a patrol boat, the buffer may be a petty officer or leading rate.

The buffer reports to the first lieutenant or deck officer, and has a wide-ranging roving commission to supervise seamanship evolutions (activities) and issue directions to seamen as required, and advise "part of ship" officers and petty officers on their activities. As such, directions and orders come with the 'line' authority of the deck officer.

The buffer will supervise major ship activities, such as: berthing alongside and taking on equipment in harbour; anchoring, mooring and weighing; rigging for refuelling or stores transfer at sea; sending away and recovering a sea-boat.

The commanding officer may occasionally call for advice from the buffer with the deck officer and executive officer in attendance, so that there is wide agreement and understanding between the senior seamanship staff.

The equivalent position in the United States Navy would be that of a command master chief petty officer in the boatswain's mate rating.

Buffer (application)

Buffer is a software application designed to manage accounts in social networks, by providing the means for a user to schedule posts to Twitter, Facebook and Linkedin. Buffer is also the name of the company that creates this software.

The application was designed by a group of European expats in San Francisco, most notably Joel Gascoigne and Leo Widrich. Gascoigne is currently the CEO of Buffer, while Widrich is the COO. By June 2015, the team reached 34 people from different parts of the world.

As of January 2015, Buffer has more than 2,000,000 registered users.
