Steak refers to a portion of meat that is sliced perpendicular to the muscle fibers, resulting in a tender, juicy piece of meat that can be grilled, broiled, or fried.

Steak is a cut of meat that’s typically associated with beef, but it doesn't necessarily have to be beef. Other meats, such as pork, lamb, and fish, can also be cut into steaks.

Beef, on the other hand, is a type of meat that only comes from cattle. It is a popular meat that is consumed in a variety of forms, such as steaks, roasts, ground beef, and stews.

There are different types of steaks, including sirloin (which comes from the hip of the cow), filet mignon (from the ribs), and rump steak (from the rump of the animal).

The most popular cuts of steak include ribeye, sirloin, filet mignon, and New York strip. These specific names refer only to beef steaks, not the steak you'd get from pork or fish.
