What is records and how represent record in memory?

A record is a composite data structure that groups together related data of different types, typically representing a single entity or object. In memory, a record is represented as a contiguous block of storage, where each field of the record occupies a specific location within that block. Each field can vary in size and type, allowing for flexible data representation, and the record itself is usually accessed via a pointer or reference. The organization of records in memory allows for efficient data management and retrieval in programming.
