An "object" is a tangible item that can be perceived by the senses. It can be anything from a simple rock to a complex computer. Objects can be classified based on their properties, such as size, shape, and material. They can also serve various functions, like tools, decorations, or components of larger systems. In programming, an "object" refers to a data structure that contains both data and methods. For example, in object-oriented programming, an object can represent real-world entities, encapsulating attributes and behaviors. This allows for better organization and reuse of code, making software development more efficient.
