Exchange rate under a floating exchange rate scheme (as often does in free market) does not stay constant. It will always fluctuate due to changes in demand and supply.
However, the state can control the supply of the currency (sell off or buy in their currency) in order to control the exchange rate. While this has been the traditional method of limiting currency exchange rate fluctuation, the global scale and scope of currency markets has significantly lowered the ability of a government to affect currency exchange rates via this method. For most major currencies, this adjustment of the currency supply can only push the exchange rate a few percentage in one direction or the other.
Instead, the method most countries wishing to fix their currency exchange rate use is called "pegging" - that is, a country legally fixes the exchange rate against a larger currency (typically the US Dollar, Euro, or Yen), and only allows exchanges of currency at the "official" rate. China is a clear example of this practice, though they are hardly the only one. "Pegging" a currency is generally considered to be a violation of free market principles, because it artificially declares the value of something without consulting the marketplace.
A fixed exchange rate system is one where the value of the exchange rate is fixed to another currency. This means that the government have to intervene in the foreign exchange market to maintain the fixed rate. The equilibrium exchange rate may be either above or below the fixed rate. In Figure 1 below, the equilibrium is above the fixed rate. There is a shortage of the national currency at the fixed rate. This would normally force the equilibrium exchange rate upwards, but the rate is fixed and so cannot be allowed to move. To keep the exchange rate at the fixed rate the government will need to intervene. They will need to sell their own currency from their foreign exchange reserves and buy overseas currencies instead. This has the effect of shifting the supply curve to S2 and as a result, their foreign currency holdings will rise.

In forward exchange rate, the rate is booked in advance for a fixed amount and period,which will remain unchanged in case of any market fluctuation or deceleration.In fact forward exchange rate booking is done to protect or guard against volatile market condition. In spot exchange rate, the exchange rate prevalent on a particular date is booked for immediate effect.

An international business will operate more easily in a fixed exchange rate system. Knowing what the equivalency of goods will allow for predetermined forecasting, however, a fixed rate decreases the opportunity for profits.
Fixed Exhange-Rate System: currency system in which governments try to keep the values of their currencies constant against one another Flexible Exchange- Rate System: allows the exchange rate to be determined by supply and demand. With a flexible exchange- rate system, exchange rates need not fall into any prespecified range.

A fixed exchange rate system is where a country's exchange rate regime under which the government or central bank ties the official exchange rate to another country's currency (or the price of gold). The purpose of a fixed exchange rate system is to maintain a country's currency value within a very narrow band. Also known as pegged exchange rate. Fixed rates provide greater certainty for exporters and importers. This also helps the government maintain low inflation, which in the long run should keep interest rates down and stimulate increased trade and investment. however I'm not sure what a currency board system is....sorry.
The rate of currency is usually fixed based on the stock exchange.
Current exchange rate for the stock market is different for every country. Encyclopedia should have a lot more information on the exchange rate from countries to countries.
