Resistors  "resist" the flow of current
have units of Ohms
ohms value can be calculated with Ohms Law
Resistance = Voltage / Current
have an associated tolerance  i.e. 20% 10% 5% 1% 0.1%
have an associated power capacity  how much can it handle
Power = Voltage * Voltage / Resistance
Diodes (rectifier type  for example)  only allow the flow of current in
one direction
have an associated power handling capability
have an associated forward voltage drop
(based on technology of the device)
have an associated maximum reverse voltage capability
want more  just ask
