What is a "toaster"?

A toaster is a small kitchen appliance used for toasting slices of bread, bagels, or other similar baked goods. It typically consists of a metal or plastic enclosure with slots into which bread slices are inserted. When activated, the toaster heats up internal elements that toast the bread by direct heat radiation. Toasters usually feature adjustable settings to control the degree of toasting, allowing users to achieve their preferred level of crispiness. They come in various sizes and styles, from simple two-slice toasters to larger models capable of toasting four slices at a time.
