A bit is the basic unit of information, and 8 bits are typically grouped together to form a byte.
A field, in the context of data, refers to a single piece of information within a record.
A record consists of a collection of related fields, such as a person's name, address, and phone number.
An attribute is another term for a field, describing a characteristic or feature of a record.
A database is a collection of organized records, storing large amounts of data in a structured and accessible way.
Records within a database are composed of multiple fields, which contain specific data about a particular entity or instance.
