Simplified answer:
TSH or thyroid stimulating hormone is the hormone that controls the release of thyroid hormone. Its release is also dependent on how much thyroid hormone is in the blood. If there is a lot of thyroid hormone in the blood, TSH secretion will be "suppressed."
T4 or thyroxine is a form of thyroid hormone in the blood.
A suppressed TSH is a diagnostic clue of a hyperactive thyroid gland. Free T4 is measured to see if it is elevated. A suppressed TSH and an increased level of fT4 will give a diagnosis of hyperthyroidism.
