Core exercise is any exercise that works any part of your trunk to your pelvic region. When most people tell me they want to work on their core, this means they want to work on their abdominal muscles. The abs aren't the only part of your core as so is your back and spine.
Static Exercise (meaning it does not use motion or movement), also known as Isometric Exercise, exerts muscles through contractions at high intensities (tensing) without movement of the joints. Pushing your hands together in front of your chest, where each side is resisting the effort of the other; or if you push against a wall without changing the angle of the elbows, are just two examples.
