Exchange rate / Rate is the ratio of one currency against another currency assessed.
For example, the exchange rate USD / CHF indicates how many US dollars can purchase one Swiss franc, or how many Swiss francs you need to buy one US dollar.

Writing pair / forex pair is always written in pairs, such as GBP / USD or USD / JPY. The reason why they are written in the pattern of the pair, is because in every foreign exchange transaction we are simultaneously buying one currency and selling another.

When buying, the exchange rate tells you how much you have to pay to buy one unit of the base currency. In the above example, you have to pay 1.7500 US dollar to buy 1 British pound.

In forex trading, you are going to buy a pair / pair if you believe the base currency will rise or rise. And conversely, you would sell the pair if you think the base currency will depreciate (go down) relative to the counter currency.
