By the principle of thermodynamics, the heat travels from one body which in contact with the other, till the point where both the bodies acquire same temperature, so conduction works in sync with thermodynamics where both bodies acquire same temperature.
In order for heat to be transferred by thermal conduction, there must be a temperature difference between two objects or regions. Heat will naturally flow from the warmer object to the cooler object until both reach thermal equilibrium. This transfer occurs through direct physical contact and the vibration of atoms and molecules.

no, conduction describes how the heat is transported not how it is generated. With conduction, a heat source is still needed.
Heat is normally transferred to specific areas by means of a 'heat sink' which is usually made of a material with low resistance and high transfer of heat. An example of this can be seen in most computers, the heat sink collects the heat from the processor, and there is (usually) a fan which is near or on the heatsink to remove it from the heat sink, effectively lowering the temperature of the processor.
Two examples of heat conduction that are observable in everyday life:- heat conduction through walls- heat conduction through clothing- heat conduction from many home appliances
conduction by itself is slower to heat but conduction and convection is faster to heat
