As far as I am aware, if is merely a pipe full of baffles to break up the shock wave of the gas leaving the muzzle of the gun.  Ofcourse, this only really works for low velocity bullets, since a supersonic bullet will still present its own sonic boom.

I always thought that silencers on guns were rather a movie makers cliche rather like opening combination safes with a stetherscope or killing people quickly and painlessly with one pistol bullet.

How silencers work is explained in part in this very forum, in the topic "thunder and lightning"

The mechanism is reflecting the sound waves, so that in stead of a short bang you hear a longer but quieter rumble.

It said that it was only good for a smal number of shots.

You can also use a 2 litre drinks bottle as a silencer, is this the same principal?

The classic (maybe a myth, but sounds plausible) was to shoot through a pillow.

A 2 litre drinks bottle might just make the average handgun a little unwieldy.

from my understanding, silencers also make the shot less accurate, making them only useful at close range. also, after a few shots the silencer won't work.

As I said, you cannot use silencers for high velocity shots, since you cannot suppress the sonic boom on a supersonic bullet - so this fact alone will mean that you are dealing with relatively low accuracy and close range.

A well made silencer, I am not aware that they have a particularly limited life.  Silencers have been fitted to submachine guns, where accuracy is not a requirement (and can even be a disadvantage), but reliability for several hundred shots at least would be a requirement (although some of the sten guns they were fitted to for covert operations during WWII were so unreliable anyway that an unreliable silencer would scarcely have made a difference).
