A logical unit of data is a virtual representation of data while a physical unit of data is the actual storage of data on a physical device. The logical unit of data is how data is organized and manipulated from a software perspective, while the physical unit of data is how data is stored on hardware such as disks or memory.
A record is the largest unit of information in the data hierarchy. The smallest unit in the data hierarchy is called a data field.
In information processing,a Data Processing System is a system which processes data which has been captured and encoded in a format recognizable by the data processing system or has been created and stored by another unit of an information processing system.
A unit of storage refers to the smallest amount of data that can be accessed, processed, or stored by a computer system. This unit can vary in size and typically includes measurements such as bits, bytes, kilobytes, megabytes, gigabytes, or terabytes. It is used to quantify the capacity of storage devices or the amount of data being processed.
A "cell" is the basic unit of data
