Depends on the country, but in the US, a 21 gun salute is reserved for the flag, the President, or foreign heads of state. 17 gun salutes are for head of Senate/House, general of the army, fleet admiral, and a lot of other high level officials.
Any battle ship entering the Port, harbour or anchorage used to give seven gun salute and in return ground batteries used to reply with 21 gun salutes. But in the British Colonial countries, some deviations were observed. The ships used to fire three extra shots after taking the reply from the ground batteries. These three shots were in Honour of the King/Queen of England, the Royal representative in the native land and for the Captain of the Ship. At later stages when royal dignitaries or state guests used to arrive, 21 gun salutes by ground batteries were introduced. Some countries went one step ahead in showing respect and offer friendship to the guest by giving 31 gun salutes. The concept of 31 probably grew as if 07 form the battle ship, 21 from the ground batteries and 03 extra (as it was practiced for the King/Queen, Royal representative and the Ship's Captain).
It is generally believed that gun salutes are set off in odd numbers because of an old naval superstition that even numbers are unlucky.***Answerer #2:Even numbers indicated a death. Important influence and reforms at the Office of the Admiralty and Marine Affairs improved the early professionalism of the (British) Royal Navy by Samuel Pepys FRS (February 23, 1633 - May 26, 1703), where the custom of firing cannon salutes originated. Partially disarming a ship by firing her cannons harmlessly out to sea showed respect and trust as well as indicating no hostile intent. At first, ships fired off all guns. Later, ships fired off seven guns, and forts fired off 21 guns. Later, the British increased the number of shots required from ships to match the forts.As naval customs evolved, the 21-gun salute came to be reserved for heads of state.

Well of course different countries' salutes vary. But as for the US there is the hand salute and gun salute. Gun Salutes are rendered as an honor for example, the arrival and departure of a President or the death of a President.

Many, if not all, US police Departments render gun salutes at funerals. This is not something reserved strictly for the military. Police render service, at risk of their own lives, just as military service members do.
To reload muzzle loading cannon, they had to be pulled back inside the ship. After firing a salute, the guns were left "run out"- showing they were empty.
