A "Blob" typically refers to a large, amorphous mass of a substance, often used in scientific contexts. In computer science, it can denote a Binary Large Object, which is a collection of binary data stored as a single entity in a database. Blobs are commonly used to store images, audio, and other multimedia files. In popular culture, "Blob" can also refer to a fictional creature, such as the one in the 1958 horror film, The Blob. This creature is depicted as a gelatinous mass that consumes everything in its path. The term has since been used in various media to describe similar entities.
