A "net" is a tool made of interconnected threads or fibers that create a mesh-like structure. It is commonly used for catching fish, birds, or other animals. For example, a fishing net helps fishermen like Bob gather their catch from the water, making it easier to collect multiple fish at once. In addition to catching, nets can also serve other purposes, such as sports. In games like tennis or soccer, nets are used to define the goal area and keep the ball in play. They help players score points and add excitement to the game, making them essential for both recreational and professional sports.
