How is trading forex different to share market?

Is it true that buying shares means you own portion of the company, but for forex, you own the currency you purchased?

Thanks for taking the time to entertain a no0b like me, this is very much appreciated.
Understoos that buying shares makes one a shareholder of the company. But when it comes to buying forex, one does not necessarily owning the currency?

Say, I am buying USD, I am only speculating that either the price will go up (of in the case of shorting, that the price will go down), but at the end of the day, I do not own the USD?

Very well written @Lupine101, now I have understood this better. I am also aware that trading currency is about betting that one currency will either strenghten/weaken against the other currency, but not about owning the said currency.

As for this, not very sure what you meant:

" Because with leverage you get to trade up to 4 decimal points for a pair. Meaning when the market is volatile, a little drop in dollar could mean nothing to the world wide currency exchange, but when its against a stronger currency you could lose a lot due to leveraged trading. "

Kindly elaborate further pls?

To confirm, the price provided by different brokers would be different, correct? Question is, would it differ by much, if compared ?

This allay my concern. Coz to me, if different brokers get to dictate their own prices, they could see what makes more profits to them.

E.g. if there are more investor betting against, say, USD to EUR, they can make them lose by indicating that the the USD fares better than EUR.

Anyways, what is pips?
