The notation $c(u,v)$ represents the capacity of the directed edge from vertex $u$ to vertex $v$. It defines the maximum volume or amount of data that the edge can carry.

Conditions: There is a directed edge from $u$ to $v$.; Capacity is a quantitative attribute assigned to that specific edge.

Conditions: There is a directed edge from $u$ to $v$.; Capacity is a quantitative attribute assigned to that specific edge.

The numbers on the edges are typically written in the format 'flow, capacity' or 'flow/capacity'. The first number represents the current flow on that edge, and the second number represents the maximum capacity of that edge.

Conditions: The diagram uses standard flow network notation.; Two numbers are associated with each edge.

Capacity is the maximum volume or amount of data an edge can carry, while flow is the actual amount of units currently passing through that edge. By definition, the flow on any edge must be less than or equal to its capacity.

Conditions: Applies to edges in a flow network.; Flow must be less than or equal to capacity ($f \le c$).
