Yes, in very small quantities

For example in the connections between the microprocessors and the pins of the same or bathing some connections.

The reason is that on the one hand it does not oxidise (it does but very little) and on the other hand, being a very ductile metal, extremely fine cables can be made

It is not a great conductor of electricity, in that sense silver would be better, but the fact that it hardly develops oxide makes it suitable

for the most part it does not oxidise, but it does not oxidise

It does not oxidise.

It depends

Gold is used in high quality connections because it is both a very good conductor and virtually invulnerable to corrosion.

However, it is very expensive (obviously), so it is used very sparingly.

In short: there is often some gold in any quality electrical device (not just computers), but you don't always find it.

Yes, it is mainly used in connections because it is a better conductor of electricity.
