Q. Which of the following is in the ascending order of Data hierarchy? Answer:
Bit–Byte–Field–Record–File—Database
Notes: Data is organized in a data storage hierarchy of increasingly complex levels: bits, bytes (characters), fields, records, files, and databases. Data are logically organized into:
Bits (characters): - a bit is the smallest unit of data representation (0 or 1);
Byte: a unit of digital information that most commonly consists of 8 bits;
Field: a field consists of a grouping of characters;
Record: record consists of fields, with each field describing an attribute of the entity;
File: a group of related records;
Database: an integrated collection of logically related records or files.
