A kinematic link is a basic element of a machine, a resistant body, which is common to two or more kinematic joints. In other words, a link is a basic member of a mechanism that moves relative to other links in the system. Most of the kinematic links are modeled as rigid links, which does not deform as it transmits force or motion. By assembling various types of kinematic links and pairs, a kinematic chain is formed.

A linkage is a collection of multiple kinematic links and joints that form a mechanism and is fixed relative to the ground. An easily comprehensible example for a linkage is the simplest Watt linkage used in the steam engines and automobile suspension systems. This mechanism constraint any sideways motion in the system. In this linkage, the mechanism is obtained by connecting the free ends of two equal length long rods to a third rod in the middle, which moves vertically, approximating a straight line.
Yes, it is a link too. The link that is fixed relative to the Earth is called as a frame.
