In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients". This architecture is called the client–server model,
and a single overall computation is distributed across multiple
processes or devices. Servers can provide various functionalities, often
called "services", such as sharing data or resources
among multiple clients, or performing computation for a client. A
single server can serve multiple clients, and a single client can use
multiple servers. A client process may run on the same device or may
connect over a network to a server on a different device.
Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Client–server systems are today most frequently implemented by (and often identified with) the request–response
model: a client sends a request to the server, which performs some
action and sends a response back to the client, typically with a result
or acknowledgement. Designating a computer as "server-class hardware"
implies that it is specialized for running servers on it. This often
implies that it is more powerful and reliable than standard personal computers, but alternatively, large
computing clusters may be composed of many relatively simple, replaceable server components.
Rackable UnitA rack unit, U or RU as a unit of measure describes the height of electronic equipment designed to mount in a 19-inch rack or a 23-inch rack.
The 19 inches (482.60 mm) or 23 inches (584.20 mm) dimension reflects
the width of the equipment mounting-frame in the rack including the
frame; the width of the equipment that can be mounted inside the rack is
less. One rack unit is 1.75 inches (44.45 mm) high. Coincidentally, 1U
is exactly equal to 1 vershok, an obsolete Russian measure of length. While the rack unit describes the height (or number of units) for
both 19-inch and 23-inch-wide racks, it is 19-inch-wide racks that are
most commonly used, which is usually 17.25 in (438 mm) wide. The 23 inch racks are from the Western Electric 23-inch standard, with holes on 1-inch (25.4 mm) centers; it is still used in legacy ILEC/CLEC facilities. The height of rack-mounted equipment is frequently described as a
number in "U". For example, one rack unit is often referred to as "1U", 2
rack units as "2U" and so on.
