mesh

Electrically, a mesh is any closed path in a circuit. In other words, it is the wire and components that form a loop in a circuit. Generally, when one speaks of a mesh, they mean the smallest possible loop from a node, across a specific branch attached to that node, and returning to the original node. The term supermesh is often used to describe a mesh that contains two or more smaller meshes.

In Computer Graphics a mesh is a surface, usually piece-wise linear, describing the object to be rendered.
It's quite common, for instance, to describe a three-dimensional object as a set of vertices, and then defining the neighbourhood relations between them: in this way you get a mesh.

Another piece of information: at the last SIGGRAPH, a whole session was devoted to subdivision, an algorithm to iteratively refine a mesh, increasing the number of polygons belonging to the surface.
