The Standardbred got it's name because that certain horse breed had a to get a "Standard" time of 2 minutes and 30 seconds over a mile to be able to be reistered. Hence, "Standard"bred.
The Quarter Horse is the fastest horse in the world for short distances, 1/4 mile, more or less. That's why they are called quarter horses.
(Assuming this question contained a typo, it has been corrected from 'What is a stranded bred?' to 'What is a Standardbred?') Also known as the American Standardbred, this horse was originally developed in America from several different breeds including the Thoroughbred, the Hackney and the Morgan. It was bred specifically as a harness racing horse with 2 types, (the trotter and the pacer), however, the breed has also shown finesse in other events. Because of its athleticism, the Standardbred is commonly seen in hunter/jumper events as well as dressage. The name Standardbred comes from the 1800's because back then, the horse had to be able to trot a mile within the standard time of 2 minutes and 30 seconds in order to be registered as an American Standardbred. Today, they are able to trot even faster. The Standardbred closely resembles the Thoroughbred but is normally a little heavier and more muscled with slightly longer bodies than the Thoroughbred. The American Standardbred is not to be confused with the American Saddlebred, a different registered breed.
The Quarter Horse is fastest for sprints. They race a quarter-mile. Thoroughbreds are fastest for anything longer than that. Arabians are best for endurance. The fastest mile for a horse was around 1 minute, 35 seconds. This record was set by the TB racehorse Salvador.
Quarter horses are the fastest horse to run a quarter mile.
There are three answers to this one as it'll depend on the distance being travelled. For sprinting a quarted mile or less the Quarter horse is fastest. For a half mile to about four miles the Thoroughbred is the fastest. Anything over five miles and the Akhal-Teke or Arabian will be the fastest.

Good ones do a mile in 2 minutes or less.
Yes they are at long distances (derby) But quarter horses are the fastest horses at 1/4 mile sprints.

The Quarter Horse is the fastest horse in the world, for a quarter of a mile. The Thoroughbred, most often used in horse racing, has more endurance for an entire mile, but still cannot beat the Quarter Horse in a quarter-of-a-mile race. Hence the name 'Quarter Horse'. This is exactly what you want in a horse when you are working cattle - short bursts of extraordinary speed.
I believe it's called the American Quarter Horse. Its name comes from the fact that it can easily outdistance other horses in races of a quarter mile or less, even from a standing start. Some individuals have been clocked at 55 miles per hour.
