Data Addressing refers to the method used to identify and access specific data within a computer's memory or storage system. It involves assigning unique identifiers, known as addresses, to each piece of data, allowing the system to locate and retrieve it efficiently. This process is crucial for the organization and management of data in various applications. There are different types of data addressing techniques, including direct addressing, indirect addressing, and indexed addressing. Each technique has its own advantages and is suited for different scenarios, impacting how quickly and effectively data can be accessed and manipulated by software programs.
