A "strong" pull (up/down) resistor would be one of a relatively low value, while a "weak" one would be of a relatively high value.
For example, a pull-down resistor would be used to keep an I/O pin low, but a button connected from that pin to VCC would bring it high when pressed, because more current flows from VCC to the pin than from the pin to GND.
In that situation, it seems any value of resistor could be used to keep the pin low, and a button press would always "override" it. What, then, would determine if the pull-down resistor is strong or weak?
Does "strong" vs "weak" only apply when one such resistor is being compared to other resistances in the circuit, such as an internal pull-down resistor?
